Truly wild to me that Dr. Al Hashimi telling Dr. Robby about her seizure disorder might be the thing that saves Dr. Robby's life? Even temporarily? Like, this man cares so much and is such a control freak, but he's also burnt out and hanging on by a thread. He just wants to get everything all squared away so he can go on vacation (kill himself).
At first Dr. Al Hashimi rubbed him the wrong way with the ai note taking and the patient passports and trying to implement changes the second she got there, but halfway through the shift, she clearly won him over. She rapidly adapted to the flow of the ER, she adjusted her teaching techniques, she called Robby out on some of his shit (a move he clearly respects even if he doesn't love it) and he was thinking; this is fine, they'll be fine without me. She's competent and compassionate and a good doctor, I don't need to be here anymore.
Then he notices something slightly off because, much like Santos, his doctor/detective brain can never shut off even though he REALLY wants to shut it off and make it not his problem. Al Hashimi shows him her medical records and the guy is trapped. He can't leave. She has a seizure disorder that was under control but just started acting up today of all days. (Which btw, poor Dr. Al Hashimi, that sucks so fucking much). He's actively in crisis but he still cares SO much, I don't think he can leave until Dr. Al Hashimi's situation is dealt with.
