Surprised by this, Serena doesn't deny Blair the chance to join and they make plans to have dinner later. However, Blair attends a small cocktail gathering for the house and accidentally stands Serena up. When Serena finds out what happened, she confronts Blair about it and comments that Juliet probably got in the way of her getting in. When she asks Juliet about it, Juliet lets it slip that Blair called to inform her about the Pete Fairman incident. However, Serena knows Blair would never pull something like that and they stage a fake catfight at Fashion's Night Out to corner Juliet into admitting she purposefully kept Serena out. As a result, Juliet is removed as keymaster for the house. Afterwards, Blair reveals to Serena that she had Dorota decorate a guest room for her at the Waldorf's so they can move in together as roommates. Serena happily accepts.

Later on, Blair decides she wants to become the face of Girls, Inc., a foundation run by Nate's mother Anne Archibald. She tells Serena, who encourages her to go for it.

When a Gossip Girl blast comes in showing a photo of Serena doing cocaine, she agrees to go back to Ostroff. Later that night, Jenny reveals to Blair that Juliet was behind the whole thing in an attempt to ruin Serena's life. Blair then teams up with Dan to get revenge and find the truth (Gaslit).

In It-Girl Happened One Night, Blair is asked to do a profile of Chuck's new girlfriend, Raina Thorpe, on Valentine's Day. Knowing that seeing Chuck with someone new will only hurt Blair, Serena convinces Raina not to do the profile behind her back. When Blair finds out what she did, she sets up Serena to catch her new boyfriend, Ben, lying to her about his job. While Serena is angry at this at first, they make up at the end of the night. Meanwhile, Blair and Dan realize they might have feelings for each other and share a brief kiss to see what happens (Empire of the Son), and Vanessa later tells Serena about it.

When Louis comes to New York to see Blair, he tells her that he's there in secret so they must keep on the down low. However, his royal minder, Jean Claude finds out he is there anyway, and Blair convinces Dan to pretend to be her boyfriend so Louis can pretend he is only in town to attend the Pink Party. Dan skeptically agrees, but worries about hurting Serena when Blair proposes they share a kiss that only Jean Claude will see. Meanwhile, Serena is suspicious of Blair sneaking around with Dan and enlists her cousin, Charlie Rhodes, to flirt with Dan at the party to see if it makes Dan jealous. Charlie is also the one to later see Blair and Dan kiss, and sends a photo of it to Gossip Girl. While this photo convinces Jean Claude that Louis is not dating Blair, this causes problems to arise between Blair and Serena (Petty in Pink). Consequently, Serena informs Louis' mother, Sophie Grimaldi, that he is dating a commoner from New York, and supplies her with a book of Blair's wrongdoings via Gossip Girl blasts. Not pleased with Blair, Sophie forbids Louis from seeing her again and plans a party for him to meet suitable girls for him to become engaged to. However, Blair is able to talk her way into the party as one of Sophie's contenders. Despite her first initial good impressions, a drunken Chuck shows at the party in an attempt to get Blair back. After embarrassing himself and her, Blair leaves the party. At home, she informs Serena that she knows she is the one who sent Sophie the book but she figured it was payback for kissing Dan. Louis overhears a brief portion of their fight and later proposes to Blair, even though he knows he does not have his mother's approval (The Princesses and the Frog).

Soon after, Serena plans a *Breakfast at Tiffany's* themed bridal shower for Blair, but asks the minions to deter her from the theme by pretending it's a cheap and boring party. Hurt that her friends don't care about her, Blair tells Louis that she wants to move to Monaco full-time to fully embrace the Grimaldi lifestyle. However, Blair is happily shocked when she arrives at the party and sees how truly her it really is. Meanwhile, Louis secretly releases Gossip Girl's sources via a list created by Nate for Serena in an attempt to show Blair how ruthless her friends really are. It comes out while the party is going on and when Blair discovers what happened, she blames Serena for posting git. Serena vehemently denies this and Blair believes her once Louis confesses he did it. Afterwards, the girls make up while eating cake (All the Pretty Sources).

After the car accident (Riding in Town Cars With Boys), Blair limits conversations with everyone, including Serena. When Chuck and Louis discover she's going on secret outings with Dan, they readily assume she's having an affair; an idea that Serena dismisses as ridiculous. At Nate's New Year's Eve party, she asks Blair what the truth is. Blair admits that she made a promise to God that she would go through with her vow to marry Louis if he saved Chuck's life, and Dan goes to church with her. Once Serena learns the whole story, she reveals to everyone that Blair has been covering for her new relationship with Dan and that they are not having an affair. Relived by this, Louis drops his accusations (The End of the Affair?). In G.G., Serena assures Blair that if she for any reason does not want to go through with her wedding, she'll run away with her. However, Blair chooses to marry Louis but the ceremony is interrupted when a video of her confessing her love to Chuck is released. Blair instantly blames Chuck, who denies sending it to Gossip Girl.

After Sophie threatens to reinstate the dowry that will bankrupt her family, Blair unhappily agrees to continue the marriage charade with Louis. Later that night, Serena admits to Chuck that she took the camera to save him from being blamed, but Chuck says he didn't do it. Now knowing that neither of them sent the video in, they wonder who really did.

In Crazy Cupid Love, Blair returns from her honeymoon to Louis and decides to set up Serena and Dan on Valentine's Day to get back together. After being able to get them both to Nate's Valentine's party, she tells Dan that if he is as wonderful to Serena as he is to her, there is no reason she wouldn't want to be with him. However, Dan kisses Blair, as she is the one he wants to be with. Meanwhile, Georgina takes a photo of the two kissing and brings Serena in to witness it. Afterwards, Dan tells Blair that he felt her kiss him back but she says she can't act on her feelings because she would never hurt Serena like that. In Cross Rhodes, she plans to prove this to her by hanging out with Dan platonically all day. After seeing a photo of them together, Serena decides to go meet up with them. However, when she arrives, she sees Dan and Blair kissing again as they try to show what a true Dylan-Clair (their character counterparts in *Inside*) kiss would be.

Outside, Serena demands that she admit she likes Dan, and Blair insists she would never hurt her and that she doesn't; but Serena argues that she can't watch Blair lie to herself. Later that night, Blair goes to the hospital to support Serena and the van der Woodsen's as her grandmother, CeCe Rhodes, is dying. She apologizes for denying her feelings for Dan and Serena accepts, saying she won't stand in the way of their being together (Cross Rhodes). After Serena is Gossip Girl for a while, she finally fills Blair in on it. While Blair is initially surprised, she's more so because she could have helped her run the site. Meanwhile, Chuck is on the hunt for Jack, who holds the answer to who his father truly is. In order to help him, Blair asks Serena to pretend to be her at an interview she needs to attend with Dan to determine whether she can accompany him on his upcoming summer internship in Rome. Serena does so and they're accepted. However, things become uncertain after Blair finds herself unable to tell Dan she loves him and Gossip Girl takes her site back; and begins posting excerpts from Blair's diary that Serena left on the computer (The Fugitives).

In the season finale The Return of the Ring, Blair is beyond angry that Serena leaked the pages of her private diary. After Blair writes a fake entry about how Serena lied about reading *The Beautiful and Damned* to get her job on the film set, the girls engage in an explosive fight that ends with Blair kicking Serena out of her penthouse for good. Meanwhile, Dan sees an entry that is posted where Blair admits she is worried she will never love anyone as much as she loves Chuck and that her relationship with Dan is only intellectually stimulating. He gives her an ultimatum to meet him at the Shepherds' divorce party if she cares about him at all and Serena attempts to stop her from going to the event. When she learns Blair is indeed on her way to the party, she brings Dan into the bar and seduces him into sleeping with her while she records it.

In Dirty Rotten Scandals, Blair is preparing for her first fashion show with the new line. Meanwhile, Serena is manipulated by Steven's teenage daughter, Sage Spence, into getting her a spot walking in Blair's show. When she approaches Blair about it, Blair agrees to let her in so long as Serena sits in the front row and will talk highly about the line to reporters. Before the show can begin, Serena gets offended when Blair seats Steven a few rows behind her to save room for press. She threatens to tell Nelly all her true opinions on the show, effectively throwing their deal out. During the show, Sage strips down to her underwear onstage, shocking the audience. Afterwards, everyone walks out and Serena and Blair each blame the other for the sabotage. However, Sage reveals she did it on her own and leaves with Steven. In Monstrous Ball, Sage discovers that Steven is planning on proposing to Serena and asks for Blair's help in stopping it. Blair agrees to do so in exchange for Sage wearing one of her dresses to Cotillion.

In the meantime, Sage has her father take a ring gifted by her mother to be resized and has someone photograph him doing so. When Serena sees the photo on Gossip Girl, she realizes Lily must have said something to Steven to change his mind and confronts her at the ball. Lily admits that Blair called her with concerns too so Serena switches her blame to Blair instead. When she confronts her about it, Blair says she only did it to get her dress at Cotillion and that she would never try to ruin her proposal for real.

However, she agrees to work with Serena when she offers to help get Sage's help in making her pop-up store a success. They set up Sage into thinking Serena is getting back together with Steven in the hopes of her coming to Blair to sabotage their relationship again.

**Serena:** Oh, B, you've had a couple of setbacks but there must still be a way to get into a great college and if anyone can do it, it's you.

-The Grandfather (2x19)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair:** I can't believe I sold out Nate to be the next Jackie O.

**Serena:** Yeah, I always pictured you as the next Hillary.

-Seder Anything (2x21)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Serena (to Blair):** You *are* high school to me. All of the boyfriends and mean girls and tests and teachers and our crazy mothers. We went through it together. We raised each other. You're my sister.

-Valley Girls (2x23)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

### Season Three

**Blair (to Serena):** This night is finally over. And as far as I'm concerned, so are we.

-The Grandfather: Part II (3x08)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Serena:** You don't need Chuck, anyone who meets you can see you're an elitist snob who is perfect to run a secret society.

**Blair:** Merci!

-The Hurt Locket (3x13)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair:** Serena! Come here. You've done some unforgivable things, like having sex with Nate when we were saving ourselves for each other or killing Pete Fairman, but how far is too far? Where is that place you can't come back from anymore?

-Inglourious Bassterds (3x17)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

### Season Four

**Serena:** I just happen to have a thing for French waiters.

**Blair:** And bartenders and museum docents, anyone on a Vespa or bicycle, or wearing Zadig & Voltaire.

-Belles de Jour (4x01)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair:** You are Serena van der Woodsen. We've been on campus, what, five minutes? I bet there's already an entire frat house filled with guys fighting over you.

-The Undergraduates (4x03)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Serena (to Blair):** I'll stay away from Nate and Dan if you stay away from Chuck and Eva. No plotting, no meddling, no Blair Waldorfing.

-Touch of Eva (4x04)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair (to Serena):** Have a little faith and if that doesn't work, a lot of mimosas.

-The Kids Are Not Alright (4x12)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Serena:** You gonna be okay alone?

**Blair:** Not yet... But I need to start learning to be.

-It-Girl Happened One Night (4x15)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Serena:** The only appeal Dan ever had to you is that he was mine.

**Blair:** You would see it that way. Because it's always about you, isn't it? I'm sorry to break it to you but Dan and I have a real connection. We did things like visit the DIA and debate Chabrol vs. Rohmer, things that we could never do with you.

**Serena:** Yeah, I'm sure you and Dan had a really deep connection. That is until a prince came along.

-Petty in Pink (4x19)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

### Season Five

**Serena:** I have to say how lucky I am to have Blair Waldorf as my best friend. I may be the maid of honor, but the true honor is just knowing you, B. There is simply no one like her, no matter how hard some of you try. Congratulations to the beautiful bride. You have become the strong, confident princess I always knew you would. I love you so much, and I wish you and your prince nothing but happiness.

-All the Pretty Sources (5x08)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Serena (to Blair):** They say people keep fighting about the same things until it tears them apart. You know what? Maybe we're there.

-Crazy Cupid Love (5x15)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Serena (about Blair kissing Dan):** Oh, so that's your excuse? Multiple Personality Disorder? Or did an alien take over your body?

**Blair:** I would never do anything to hurt you.

**Serena:** Too late.

**Blair:** Look, it was a mistake, what do you want me to do? Self-flagellate? Wear a hair shirt?

**Serena:** If you're referring to the hideous fur vest you wore yesterday, I'm the only one who suffered because I had to look at it.

-Cross Rhodes (5x16)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair (to Serena):** It is your destiny to be gossip worthy.

-It-Girl Interrupted (5x19)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair:** Why didn't you tell me?

**Serena:** I don't know. I felt like it was something I had to keep secret from everyone, I mean, my best friend even. I know it was wrong and I'm so sorry.

**Blair:** I mean, I could have helped! Sealing fates, forging destinies, like an imperious Greek Goddess imposing her will on the guileless masses. But, I was wondering why Gossip Girl has being so nice to me lately. And a little off her game. No offense.

-The Fugitives (5x23)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Serena:** Oh come on Blair, you're the one who can't move on. You're still in love with Chuck and you still won't admit it.

**Blair:** Get out. I mean it. I want you gone for good. Pack your things.

**Serena:** You can't hold me responsible for everything bad in your life.

**Blair:** I can because you are. The best time I ever had was when you were gone six years ago.

-The Return of the Ring (5x24)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

### Season Six

**Blair:** So what you're saying is that you want to use me, your non family, to make a good impression on your new, real family.

**Serena:** Yeah.

-Dirty Rotten Scandals (6x03)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair (to Serena):** I would never try to take away your happiness. At least not permanently.

-Monstrous Ball (6x05)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair (to Serena):** This line was inspired by both of us, ruling Constance together. This is your success too.

-Save the Last Chance (6x07)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair (to Serena):** But there's no Sara Beth's in LA. Or Serendipity. Or me.

-The Revengers (6x09)

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

**Blair (on Dan's wrongdoings):** Chuck is one of us. Whereas Dan, despite his years of trying, never will be.

**Serena:** What does "one of us" even mean after all this time? He's friends with our friends, we both dated him, his father married my mother, his new apartment is in my building..

**Blair:** S. We all hoped that Humble Humphrey would overcome his Brooklyn roots to join a higher social strata. I mean after all, it's the American Dream but in his case the dream has died.

**Serena:** Just give him one more chance. You don't know the whole story.

**Blair:** I know what I need to know. And that is: Serena van der Woodsen will never end up with a powerless striver.

-New York, I Love You XOXO (6x10)
