Jackie closes the curtains, and nods when Paula suggests he should just kill the cat. No, that's not what she says. What Paula says is, "He needs to kill that cat." What Paula says is that something only has to hurt you so many times before you're ready to say goodbye.
Then it's later, and as Jackie pulls morphine into a needle, Elenor stands against a bathroom stall door, breezily: "You better not care more about that old nurse than you do about me, by the way." Inside the stall, Jackie worries over it; she'll need five times that much to get it done. Zoey comes looking for Jackie, but spotting Elenor, immediately disappears again. Jackie's voice is a little shaky as she tells Elenor it's better for her to leave for this part. "Nonsense. Nothing's better if I leave."
(I'm fairly certain I would adore Elenor in real life, and I love Jackie in all universes, and Coop is a foregone conclusion, but the proof that this show has accomplished creating its own tone and universe is the fact that I find Zoey hilarious and adorable on TV, but would hate her blackly in real life. If ever you think Elenor and/or Jackie are ever being bitches to her, remember that I would do worse. Gleefully. With malice of forethought. Nothing brings out my inner bully like this type of creeping, flesh-crawling awkwardness and aggressively tone-deaf inability to relate to human beings. On TV, my God she's awesome, but as an object lesson in what not to actually do, ever, she's like a red flag waving in front of a bull.)
Coop explains every single detail of her gall bladder surgery to his mother, finally prodding Elenor to ask if the textbook point-by-point was really necessary, and both moms assure her that it is. Mrs. Cooper likes to know everything before it happens, she says, and Mrs. Scheinhorn rolls her eyes: "She's impossible to watch movies with." Mrs. Cooper asks Elenor to let her son "assist in the opening of [her] abdominal wall," and Elenor finally relents, "as long as he doesn't touch anything." Which is a funny line, but we don't know that yet. So Elenor removes it, and he asks to see it, and he asks for a jar to put it in, and then his mother's BP drops suddenly, and he responds by grabbing Elenor's breast. She stares him down, he notices (or "notices") and lets go: "There's a good boy."
(It is vertiginous, though, because he's such a fraud and because I think he honestly doesn't know when he's defrauding, but we know from this episode that he did grow up with OCD and Tourette's, in some form, and although it's doubtful that he would act out like this consciously during his mother's life-threatening moment on the table, he's still such a giant asterisk that I don't feel we can definitively say what's going on. I'm sticking with "And neither can he.")
