So despite having recapped 60-something episodes of this show, and knowing full well that there was a prestigious fictional award called the Harper Avery Award, I still somehow neglected to notice that one of the Mercy Westers was named, hmm, Jackson Avery. It turns out Meredith isn't the only one at the hospital with a famous family member, as Harper is Jackson's grandfather, and Jackson has an incredibly difficult relationship with him on account of his medical fame. Harper is rushed in with abdominal pain and then, when he's told he needs surgery, orders the doctors to let him stay awake so that he can see what's going on. When Derek tries to talk him out of it, Harper basically mocks his being Chief and looks more to Richard. He wants Richard to do the surgery, as he is the only one Harper actually knows and trusts. It's Richard's first day back and he wanted an easy day, but he agrees, and the only hitch during the surgery is when Harper orders him to use a different type of suture than Richard was planning to use. Afterward, Meredith convinces Jackson to talk to his grandfather and learn from him while he has time, but it dissolves into a fight that is then interrupted by Harper's cardiac arrest. Richard doesn't want to be the one to perform the fix-it surgery because he's terrified he made a mistake the first time around that caused this, but Derek assures him he can do it and sends him back in, where they find that Harper had an allergic reaction to the sutures that he had wanted. Richard is thrilled that he did in fact do everything right and actually none of this would have happened if they had done things his way in the first place, which makes up some for the humiliation of having to now submit urine samples at work so that they can make sure he's not sneaking any drinks. Derek, meanwhile, is having some trouble asserting himself as Chief, but when he finally has to stand up to Harper before his second surgery it seems to get him going in the right direction, and he and Richard seem to start to work at being able to coexist with their new backwards boss/employee relationship.
Cristina, meanwhile, is having a hard day on account of having misdiagnosed Harper before she even knew who she was. She and Lexie are working on Teddy's service and Lexie is having her own bad day since everyone thinks she has feelings for Alex now that they are sleeping together. She wants to prove she's a badass, and Cristina wants to do something incredible that Harper might hear about, so they wind up kinda/sorta stealing some lungs that were going to be tossed rather than donated and do some crazy, barely-tested procedure to implant them into their patient who is too sick to get garden-variety donor lungs. Teddy is furious when she realizes they stole lungs behind her back, and then freaks out during the surgery when complications. But Cristina manages to get her mind back to the surgery and they work together and manage to save the kid's life. They celebrate with a girls' night that Arizona planned because for ONCE someone in the hospital noticed the obvious -- that Teddy was mooning over Hunt. She convinces Teddy to hang with her and Callie and to become friends instead of just making sad puppy dog eyes at Owen, and all of the ladies wind up having a bonding, celebratory night of playing baseball.
So the five men who watch this show are given a thank you for doing so when treated to shots of Lexie trying to arrange herself in a sexy pose on a bed, wearing only the bedsheet. As she tries out different poses, Mere starts, "Surgeons are detail oriented. We like statistics and checklists and operating procedures. Our patients live because we enjoy following the steps. But as much as we love to always rely on the numbers, the plan, we also know that some of the greatest medical discoveries have happened by accident." A fair amount of time is clearly passing, and Lexie is fidgeting. She finally decides to wait with the sheet pulled back to show off her lovely lady lumps, and of course that is the moment that Derek, not Alex, walks in to the room. They both yelp, horrified, and as Derek flees Meredith appears in the door. Alex left ten minutes earlier (shame Derek didn't realize that before he walked in) and when Mere asks, Lexie admits that she and Alex have been hooking up since Mere caught them the first time. She warns her little sister that Alex is emotionally like she was three years earlier and therefore totally unsuitable as a crush. Lexie tries to claim that it's just sex with no feelings, but Mere laughs her off because she knows Lexie too well, and points out, "Your heart lives in your vagina." Lexie tries to deny it and then, realizing that it's futile, tells her it's not like that this time. Mere laughs in her face about this and heads off to work.
"Mold: penicillin, poisonous tree bark: a cure for malaria, a little blue pill for hydropressure: impotence be damned." As Mere's VO lists famous medical discoveries that were accidents, Derek arrives at the hospital to find some doctors giggling and listening to moaning coming from behind a door. He shoos them away and walks right in, only to find Mark with his pants down, holding a woman up against a supply rack. She's horrified but Mark just seems pissed to have been interrupted, and Derek storms away muttering, "Why is this my morning?" hilariously leaving the door wide open as he stomps off.
Cristina and Hunt are walking in to work and she excitedly tells him about a surgery that she and Teddy performed when he gets a page. He is quiet and she knows something is wrong and asks what's up; he says it's nothing and then immediately comments on how she and Teddy are friends now. Cristina tells him that she is and then sincerely tells him that he can be friends with her too, reminding him that she never told him not to. It's definitely coming from the new, more mature and gentle Relationship Cristina perspective when she tells him to be friends with her. Mere VO's: "It's hard for us to accept that it's not always the hard work or attention to detail that will get us the answers we're looking for. He thanks her and they are kissing when Charles walks out, pissed to find them so as he just paged Hunt about an incoming trauma. The paramedics arrive and unload a motorcycle-riding, helmet-eschewing daredevil with a closed head wound, among other things. He's barely alive, which is just as well given that as they start to run inside, one of the medics slips on some water (it's pouring rain out) and she and the gurney come crashing down to the asphalt.
