Cuddy messes with Murphy's IV bags and asks where her sister went. "She's got a family," Murphy says. Cuddy points out that she, too, has a family. That just sets her up for Murphy to say "three kids and a husband -- that's a family." Cuddy decides this is a good time to ask her mother why she has always been harder on her than her sister, like when she made Cuddy be her high school yearbook editor but let her sister do whatever she wanted. Murphy's like, "um, that was decades ago." Cuddy says she still treats her that way. Murphy says if Cuddy wants her to tell her that she loves her and her sister equally, she does. "Okay," Cuddy says, and starts to leave. But Murphy isn't finished. She feels the need to add that she likes Cuddy's sister more. Why would she even say that? So unnecessary.
Taub finds Foreman relaxing in the light-free doctor's lounge. Foreman says the angiogram results on that kid came back. He points something out on a film that I don't know how anyone can actually see since, again, there is no light in the room whatsoever, and says the thing Taub thought was a bleed in Timothy's brain was actually just an "anatomical variant" that Timothy was born with. That means Taub risked everything and there was nothing wrong with Timothy after all. Oops.
There is, however, something wrong with Murphy. She's having trouble breathing and all the symptoms of an allergic reaction. But, Kaufman says, that's impossible since Murphy was on prednisone, which is used to treat severe allergic reactions. Way to switch Murphy's prednisone out for an antibiotic she's allergic, too, idiots.
