Cristina is back from her mandatory leave of absence from the Mayo Clinic where she Googled the Mall of America instead of actually going there. The head of cardio, Dr. Parker, wants to be sure she's ready to be a team player. So he assigns her to a rotation with the totally old school Dr. Thomas. Cristina is pleasantly surprised to learn something she never thought was possible during one of his surgeries.
Remember how we said April was re-virginizing? Well, she may have to re-re-virginize after being unable to control her passion for Jackson. In other news, Bailey is frustrated that her former charges have taken over the Attendings Lounge. She leaves Post-It notes everywhere to get them to clean up their act. For the record, they are yellow Post-Its, not blue. So, no one got married in the lounge.
The real reason Bailey is upset is because Tuck let go of her hand and didn't even look back his first day of kindergarten. Richard encourages her to doing something great now that she has that hand free again, and she shouldn't look back. Speaking of not looking back, Cristina lets Owen know that they can't keep chatting like old times. She's in Minnesota now. That's where she needs to move forward. A nice little after-shift talk with Dr. Thomas has us believing that's exactly what she intends to do.
