Dr. Singer's test results are back and Izzie rips them out of annoying Dr. Percy's hands. The results are all normal, but she demands a spinal tap, too. Dr. Percy is unimpressed by this request, because he thinks that Izzie just wants to make a miracle diagnosis and win her job back. Izzie swears that she doesn't want her stinky crappy job back, but just wants to see her beloved mentor well again. No one believes her. Dr. Singer wakes up confused and disoriented and gets out of bed. When Izzie tries to convince him to stay he ends up falling flat on his face on the cold hard floor. Good thing Izzie was already fired, because otherwise that would do it.
Bailey has finally found the Chief. He is snoozing in the on-call room (how handy that no one was having sex in there for once). She nudges him awake and jumps back. He wakes with a start. Bailey gives him the bad news that he has an emergency surgery and his wife is there to see him because he is in trouble. She hands him his latte.
Izzie pesters Dr. Percy about getting Dr. Singer a spinal tap. He doesn't think it is called for, but Izzie has no qualms about giving an old man an incredibly painful procedure just to prove she is right. When Percy still resists, Izzie blackmails him by threatening to tell the girl (Reed, I think) that he loves her like no other. He caves. Obviously.
Back in the cardio trauma drama, Yang is shocked when her Cardio God confesses that she hasn't put in a pacemaker in ten years. She doesn't even care that Teddy was going to let her do the procedure, she's too unnerved by her attending's lack of practical experience. So Avery does it and Yang goes to talk to the Chief. Teddy still doesn't seem to care.
Meredith finds Alex who is either working or hiding. Maybe both. She reports that Izzie has been staying with her mom in Chehalis and has been keeping up with her cancer treatment. Alex doesn't say anything, so Meredith leaves. Meanwhile, Bailey has the Chief vertical, caffeinated, and heading into surgery when Yang finds him. Bailey acts as human firewall to prevent the Chief from engaging with Cristina. Bailey reminds her that she asked for a new cardio attending and the Chief found one after another and Cristina ran them all off. Cristina protests, but no one can really argue with Bailey when she's on a roll. Bailey asks Cristina to consider that perhaps she might be the problem. Cristina is flabbergasted and looks to the Chief, but he seconds everything that Yang said. Bailey sends the Chief off to surgery with an overly touchy arm shove that the camera zooms in on and shows in slow motion so we know we should pay extra close attention. Mark and Callie come ask Bailey about some patient, but Adele doesn't pay them no mind. She just wants to know if Bailey is having an affair with her husband. While Bailey is vehemently protesting, Callie and Mark look like they just won the gossip lottery, which they did. Obviously they don't have the decency to leave Bailey and Adele to fight in peace. Bailey is completely horrified by the accusation, but Adele saw that arm touch and she knows that they finish each other's sentences and spend hours together everyday. After listening to this compelling argument, Mark seems to agree that Bailey is definitely having an affair with the Chief. Callie, however, knows a "work husband" when she sees one. She clumsily explains to Adele that Bailey and the Chief are merely meant for each other at work. But this does not mean they are having an affair. This does not really help the situation. Adele finally concedes that maybe Bailey is not sleeping with the Chief, but after years of watching the Chief during his affair with Ellis Grey, she knows the signs. The Chief is having an affair with somebody. Mark and Callie, chuckleheads that they are, giggle like tweens at a New Moon opening. Adele deigns to glare at them and they scamper.
