Meredith has finally changed out of her scrubs and back into street clothes, and Derek finds her cleaning out her locker. He's not there for some sort of touching goodbye, though; he demands angrily to know what she said to Janet. Mere is surprised and sincerely tells him that she said nothing, but Derek spits that he just answered a ton of questions about Zola's sleeping arrangements, and that he was told there were inconsistencies with their stories. Well yes. When both of you have decided that lies are the best option, but you refuse to speak to one another to coordinate those lies, that's going to happen. It's extra dumb because Meredith once again, however misguided it may be, was lying to protect the ones she loved who in this case are Derek and Zola. He gets a page and Mere tells him that she'll go talk to Janet but he sharply informs her that she'll do no such thing, and that he will take care of it. Because he's done such a good job of it up until now, you know.
Jackson finally had a chance to re-do Jerry's sutures, and he's wriggling with excitement to show off his work to Mark. They walk over to Jerry's bed and he pulls back the curtain... to reveal a very confused old lady. Mark mocks him some more for now losing a patient and storms off. April then runs up to ask another favor and Jackson snaps and yells at her to do her own work. He also asks where his patient might be and April is thoroughly confused for a moment because her precious board says that he should be right there. After a beat, she realizes that this might have caused a very big, very serious problems, and she yells, "OH NO!" repeatedly as she sprints away.
At that moment, Lexie and Bailey are preparing to do a spleenectomy on some guy named Chuck. Bailey's impatient to get the show on the road, but Lexie actually follows April's checklist and looks at his release form first. Bailey is hovering over Chuck with a scalpel like a starving man over a Renaissance Faire-sized turkey leg, when Lexie realizes that something might be wrong. She tells Bailey to hold up and then finally realizes that they have totally the wrong patient on the table in front of them. She's freaked out and repeatedly apologizes, then is interrupted by April who runs in screaming to stop because this is the wrong guy. Bailey very slowly and carefully hands the scalpel back to a nurse.
