passage: Dr. Bailey is in labor, and without her husband Tucker Jones by her side, she refuses to push so she can give birth. George works with Addison to convince Bailey to have the baby. He finally gets through to Bailey by giving her the motivation that she needs, and ultimately he holds her while she delivers the baby. Izzie and Alex have sex again. Chief Richard Webber is under a lot of stress from everything that's been going on, and it is believed that he is having a heart attack, which lures his wife Adele to the hospital. However, it proves to be just an anxiety attack. Dr. Bailey's husband goes into cardiac arrest. Meredith finally removes the explosive from the patient, and Dylan, the leader of the bomb squad, carries it away. Meredith steps out of the operating room into the hallway, curiously watching Dylan walk away with the explosive, and at that moment, the bomb explodes, killing Dylan and a second bomb squad member. Meredith is knocked unconscious by the explosion. There is a revival of the ``shower scene'' from the first part, but with a more serious tone: the fully clothed Izzie and Cristina wash blood off of a stunned Meredith as George looks on. Dr. Bailey's husband and the man who had the explosive embedded in his body both survive. At the end of the episode, Preston and Derek become friends, overcoming their initial rivalry in the series beginning, and call each other by their first names. Cristina says ``I love you, too'' to a sleeping Preston. Derek comes to visit Meredith and says, ``You almost died today,'' and Meredith tells him that she can't remember their last kiss. Derek recalls the kiss for her, telling her that she ``smelled like some kind of flower,'' which Meredith says was lavender, and then he leaves.

passage: Despite the fact that Brenda never appeared on the screen, she was nonetheless present during occasional discussions during the following six seasons of the series. The most significant among them is her reconciliation with Dylan, who was going to move in with her. It is assumed that they were together for most episodes of the seventh and eighth seasons of the series, as during an episode of season 8 where it is learned that Dylan's half-sister was saved from a life of prostitution and then left to live with Dylan and Brenda in London and Kelly and Brandon mentioned going to visit them for part of their honeymoon. Later, when Dylan returned in season 9, he told his friends that he and Brenda had separated two years earlier. However, it frees Dylan to resume his relationship with Kelly.

After they save Padmé, now a senator, from an assassination attempt, Obi-Wan goes on a solo mission to trace the bounty hunters involved to the planet Kamino, where he learns of a massive clone army that the planet's inhabitants are building for the Republic.
