The next thing we see is Addison striding off the elevator like only she can do, and a relieved Mark immediately tells her that the baby's right leg is worse than his left. Addison takes a moment savor calling Mark "grandpa" a few times -- I mean, priorities, people. They then walk up to the whole gang working on Tom and the others are all surprised and happy to see her. Bailey snaps at a hapless tech who brought her some results slower than she would have liked, and after she goes back into Tom's room, Addie notes that she is "perkier than usual." Callie thinks Bailey's mood (which honestly, doesn't seem any different from Bailey's normal mood, but clearly we are all supposed to just play along) is due to her divorce and thinks she needs someone to help her move on. Addison tells Derek to find her someone, suggesting a Dave in oncology, but Derek declines to get involved. Once they are all gone and he and Bailey are the only ones left, though, he does suggest Dave and drops that he's single. Bailey naturally shuts him right down, warning him never to get involved with her personal life.
Teddy introduces Cristina to her patient, Ruthie, who is charming and sweet and shockingly, Cristina is actually incredibly pleasant back. After a few moments, though, her good cheer starts to fade. Ruthie, while sweet, wants to go over all of her allergies, and this turns into her worrying about every little thing including dust mites in her pillow, and she asks to have a new nurse. All of this still doesn't prepare Cristina for where Ruthie goes next, which is saying she's worried about her new mechanical valve making a clicking noise. Cristina immediately tries to brush off her doubts since switching up and using a porcine valve would be a whole different procedure than what they planned, but Ruthie is really into the idea of a pig. Teddy watches with bright-eyed amusement as Cristina is finally left speechless by Ruthie's musings.
