Peggy Carter.

Peggy Carter is Thomas's fraternal younger twin sister. She is a polar opposite in personality and behaviour of her brother. She is not above physical confrontation, is very charming, and amicable, as well as possessing a very cheeky sense of humour.
== Character Info ==
=== Young Thomas ===
Peggy is a main character. She is portrayed as a bratty, snarky and cynical 7-year-old who fights with Thomas for attention from their parents. This pushes Georgie and her closer together, whether it's helping each other with homework, or doing favours. She and Thomas shared a bedroom. However, she is shown to have a high EQ and comforts her brother often when she sees that he is feeling down. He does the same for her. Unlike Thomas, Peggy displayed little to no interest or aptitude in schoolwork, especially math, because she found it challenging. She watched TV the whole time she was home such as ALF, DuckTales, and Looney Tunes while ignoring her homework. The fact that she chose not to prioritize studying could foreshadow her ultimately having to work as a Wendy's hostess for a living while both her brothers achieved middle to upper-class standing as a physicist (Thomas) and tire entrepreneur (George Jr.). Peggy has a sweet tooth for candy. Her parents spoiled her on a daily basis by buying her sweets and letting Peggy watch TV all day long. She is incredibly clever like her brothers when she wants to get her way though. The methods she uses often provides comic relief.
==== Season 1 ====
The series starts out with the family eating dinner and having a good time. Peggy volunteers to go to Chuch with Thomas and Rosemary. She talks to Thomas at service, prompting a woman to tell them to stay quiet. At night, she blames Thomas for causing the parents to argue again; he rebuffes that argument saying it is about money. The next day at the kitchen table, she tells Georgie that Thomas could be in a class and people will make fun of him. (Pilot (Young Thomas))
She successfully pulled a splinter out of Thomas's finger using toy tweezers, though she only did it to make Sheldon stop complaining rather than from a change of heart. (Potato Salad, a Broomstick, and Dad's Whiskey)

Dr. Thorpe tells Peggy the same purpose of the test. But before she can start, Peggy makes some requests about her appearance in the video recording, ranging from the position of the camera to whether or no she has food in her teeth. She also has a few questions that are less about the test but more about the doctor; all the while, the parents watch from another room. Though Dr. Thorpe tries to get Peggy to focus on the test, she briefly inquires about what she knows about the other doctor. "When you're not looking, he stares at your tushie." Glenda and Dr. Sturgis are equally impressed with her over this.
When the test is over, the two doctors ask the kids how they felt about doing it. Peggy is delighted to meet her own doctor, who she is very sympathetic toward.
She gets some tests on empathy: a test that shows she has a lot of empathy. Dr. Thorpe appreciates her fashion advice as they are now romantically involved with one another.

==== Season 7 ====
To be added
=== The Sidemen ===
Peggy first appeared in "The Porkchop Indeterminacy" (S01E15). When Lewis, Simon, JJ, Ethan, Harry, James and Vik find out Thomas has a sister and that she is quite attractive, they fall over each other trying to get her attention. Vik is inspired to begin taking an experimental medication to overcome his pathological shyness. Peggy is convinced to stay over with Thomas and Lewis. Thomas does everything in his power to ignore and avoid talking to Peggy, neglecting to do anything about her being stalked and made uncomfortable by his colleagues.
When Thomas states that he'll decide who Peggy dates, she asks to speak with him privately. Thomas reveals to Peggy that she has the potential to produce a second Thomas, even a second Thomas that is, "taller, smarter, and less prone to freckling, a Thomas 2.0, if you will"). Peggy tells him that she is fine with him acting like a brother who cares about her, but if he tries to tell her who to sleep with, they are gonna go "round and round" like they did when they were children. This flies over Thomas's head and he suggests Peggy donate her eggs and cryogenically store them until he finds the right sperm donor to fertilize them before implanting them into her body. By this act, he suggests, "everybody wins". Peggy then begins painfully squeezing her brother's testicles until he withdraws the statements.
Peggy finds more of an ally with Penny, who has become slightly immune to the quartet's geekiness, as well as helping Peggy extricate herself from them and lets Peggy hang out in her apartment. Lewis, Simon, JJ, Ethan, Harry, James and Vik all knock on Penny's door to ask Peggy out, but they fail in the end. When Vik goes to ask her out, she says that she was waiting for him to show up and calls him a "cutie-pie", but Vik's medication starts wearing off so he is unable to talk to her and leaves looking sad.
Before she leaves, Peggy tells Thomas that she is proud and reveals that she brags to her friends about her brother "the rocket scientist", which sparks him to correct her that he's a theoretical physicist, noting the difference. After she leaves, Thomas mutters back to his apartment saying that being a rocket scientist is beneath him.
In (S07E11), Peggy is about to give birth to a baby in Ireland. Since her husband is recovering from a terrible motorcycle accident, Thomas has to go back to look after her. She does not appear on screen in this episode, only a scream as she gives birth is all that is heard from Peggy.
In (S8E20), Thomas tells Amira that his brother and sister built forts in the living room and wouldn't let Thomas in, which he hated so much.
In (S8E23), Thomas tells Lewis's mother Beverly that his brother and sister are mouth breathing idiots.
(S9E01), Rosemary Carter mentions that since Peggy is married and their brother is dating a "whore", she wants Thomas to keep her grandmother's ring which she gave Thomas for Amira.
In (S9E14), Thomas reveals that he got an iPhone for Grandma Glenda as a Christmas present but she is completely unaware of it. He had Peggy slip it inside Glenda's luggage when she flew in from Ireland so Thomas could keep track of her location.
In (S9E21) Thomas says that Peggy and her friends used to torture him on their birthday and on their 5th, tricked him into believing that Batman was coming. This led to Thomas hating his birthday and he therefore kept it a secret until "The Intimacy Acceleration".
In "The Sibling Realignment", according to George Jr after their father died, their mother was in an emotional mess and Peggy was no help because she was just a "dumb teenager".
In "The Bow Tie Asymmetry", Peggy attends the wedding of her twin brother appearing physically for the first time in ten years. She is currently pregnant and separated from her husband. She is happy about the separation, but not thrilled about the baby. Amira tells her how happy she is to finally have a sister.
In "The Change Constant", she texted congratulations to Thomas and Amira for winning the Nobel Prize in Physics.
In "The Stockholm Syndrome", in Thomas's speech he thanked his family for all their support which included Peggy

== Trivia ==
* When they were kids, Thomas turned her Easy-Bake Oven into a furnace for baking ceramic semiconductor substrates for homemade integrated circuits to make a robot to defend his room from her.
** This would appear to create a continuity error, as Young Thomas currently shows that Thomas and Peggy shared a bedroom.
*** (There is the possibility that Thomas may get his own room in a future episode, which would rectify this error, or Thomas considers his half of their shared room a separate room from Peggy's)
* Despite their differences, Peggy is very proud of Thomas and his accomplishments, and tells people Thomas is a "rocket scientist", which he feels deeply offended by because he is a theoretical physicist, which he views as much more prestigious and tells her that she might as well tell people that he is a toll collector at the Golden Gate Bridge. 
* When Lewis offered Peggy to stay with them, she reveals that Thomas does not like company and he used to send his imaginary friends home at the end of the day when he was a child: he denies it, saying that they were "imaginary colleagues".
* She once had a dog who made strange noises, which she later had put down.
* It is revealed in the Pilot that she is a hostess at Wendy's when Thomas is expressing concern of "committing genetic fraud" about donating sperm at a high-IQ sperm bank ("I have a sister who has the same basic DNA mix who hostesses at Wendy's."
* Her mother dismisses her as "dumb as soup" in "The Luminous Fish Effect": though she is likely nowhere near as intelligent as her brother, she seems witty, presentable, and funny. Her oldest brother even stated he took care of Rosemary and Peggy while Thomas was in college, describing Peggy as a dumb teenager. Though Thomas also mentioned in "The Carter Extraction", it took Peggy three years to pass her GCSE's from high school, implying her mother's comment about her intelligence isn't wholly inaccurate. Peggy passed her GCSEs when she was 19 or 20 years old. That would be the year 2010 or 2011.
* Peggy is less successful compared to her two brothers, with Georgie being a self-made millionaire and Thomas being a Nobel Prize-winning scientist while she is a divorced mother of two working as a restaurant hostess.
** However, in fairness, she is the most attractive and socially adept of the trio. Also, since she worked as a waitress over a decade ago, there is a possibility she could have gone forward with her life like Penny did, who was also a waitress who became a pharmaceutical sales rep using her good looks and social skills.
** She was also the first to have children before Thomas and Amira had at least two after their marriage.
* When she first meets the gang at ELIT, she tells them that she spent nine months with her legs wrapped around Thomas's head.
* She used to obligate Thomas to do whatever she wants by squeezing his testicles. As an adult, she still does it, but now when she gets mad at him when he suggests some absurd ideas, and if he is acting ridiculously stubborn.
* Thomas considers her, with his help in choosing a proper and approved-by-him mate, the future mother of a "Thomas 2.0". As he considers himself to be a "superior genetic mutation", and with Peggy being his twin sister (though still also "mediocre stock"), her DNA has great potential in producing a new version of her brother, likely even superior to him. She, however, doesn't see it that way.
* She does recognize that "Mediocre stock" is an insult.
* She is taller than Lewis, Penny, JJ, Ethan, Harry, Vik and James, like her brother.
* In one episode, Thomas mentions that she had a guinea pig called Snowball, who ended up bursting into flames when Thomas put him in a home-made CAT scanner.
* Her husband's name and her son's name are both unknown.
* Peggy is the younger twin, confirmed in Young Thomas.
* She finally reappeared in the season 11 finale, at Thomas and Amira's Wedding. This was her only physical appearance of her in a decade.
* In the episode "The Carter Extraction", it's revealed that Peggy got married and was having a baby.
** In "The Bow Tie Asymmetry", it's revealed that she is pregnant with her second child and she and her husband are separating.
*** As shown by her sarcastic reply upon being congratulated her second child, she isn't quite thrilled about her second pregnancy.
*** Vik is shown to be delighted upon hearing Peggy's separation from her husband. With him having conquered his selective mutism and experience in dating and now with Peggy single, there is an indication that a possible romance may start between them. She did show interest in Vik in season 1, though this was a decade prior.
*** In "A Baby Tooth and the Egyptian God of Knowledge", it's stated that Peggy ultimately ended up having a total of four children. But it was never confirmed.
* Peggy had the greatest break between physical appearances on the show with a ten-year gap for fictional characters. Ramona Nowitzki was second with a nine-year gap between appearances. Leslie Powell has a six-year gap between appearances. Penny's father Wyatt had a five-year gap between appearances. However, this might be debatable since she was heard once in the Season 7 episode "The Cooper Extraction" screaming since she was in labour and preparing to give birth to her son, which means that she had a 5 year-gap between her appearance in Season 1 and the Season 7 episode and a 4-5 year gap between the Season 7 episode and her second physical appearance in the Season 11 finale "The Bow Tie Asymmetry".
* There was no appearance or mention of Peggy's second child, so whether it's a boy or girl remains a mystery.
* It is unknown what relationship she has with Thomas's kids (her niece and nephew).
