Derek just yells that Lori didn't consent to that part of the surgery -- which, fine, is an incredibly valid point, and Mere's argument that, "It was right there!" doesn't really hold up against that. But when Derek yells that she should have paged him, Mere wins that one by pointing out that she did, twice. And I would add that he had specifically told them to call if they needed anything which implies that he would then answer. Yes, Mere assured him that they wouldn't need anything, but he should have known then that if they were trying to get a hold of him, it was most likely important. Oh good grief, why am I wasting this many words on this argument? I completely understand that Mere wanted to take out a brain tumor that was staring her in the face and was supposed to be a simple procedure. Derek's wrath becomes understandable later but right now he just seems pissed that they made a decision without him and it's infuriating since she specifically tried not to end up in this situation from the beginning but he insisted. The other doctors and nurses in the room all squirm as this fight unfolds in front of them and Derek demands to see all of the scans and to know exactly what he and Lexie did. Mere seems pretty justifiably fed up.
As Catherine and Richard work on Irene Catherine continues to flirt away, batting her spectacularly long eyelashes at Richard with every chance she gets. Bailey just rolls her eyes and reminds them that she's holding on to a bladder for them whenever they'd like to actually do some work. Mara finds them and asks if she can scrub in, since Jackson is nowhere to be found. But Catherine is ticked off to hear that her star fellow lost her son and orders her out to find him, insinuating that if she doesn't, she's not going to get to go along to the benefit. Once Mara shuffles dejectedly out of the OR, Richard comments that a benefit sounds like fun, but she counters that it is exhausting. She talks about how, once she became an Avery, she had to start acting the part, going to every single event and representing the family. Not to mention always doing Harper Avery-level work while not actually being eligible to win the prestigious award. She complains that the name comes with too much pressure and can cause a person to burn out, which is what happened to Jackson's father and she's adamant that it not happen to Jackson too. Do we know what happened with Jackson's father? It only occurred to me during this very scene that he's not around, what with Catherine flirting with Richard, but I can't for the life of me think of what happened to him and Dr. Google is being no help at all on the subject. Richard makes understanding noises and she asks him if he ever wants to go back -- she definitely would enjoy being regular, fun, Catherine Fox again. Richard dutifully tells her she's fun now, and Catherine practically purrs that she's glad he noticed.
