fear of a direct hit

harvey does not care about rachel's well-being At All. except for when it's making mike sad. except even then he doesn't give a shit about rachel, because her getting better or whatever is just the most effective means of making mike happy.

but yeah it's very funny that mike doesn't particularly care about rachel being hospitalized, either. he does the whole "i'm going to be here when she wakes up!" kerfuffle, but then harvey invites him out to a steakhouse and he's basically like "no i can't! i have to wait for her! wait did you say you're buying okay whatever let's go." and then as soon as harvey gets it off his chest that he feels guilty and mike needs a distraction, they're back to talking about themselves. and making fun of louis. rachel? sure, sure, she'll be fine, let's talk about literally anything else.

it may well have been patrick's acting choice (and gabriel's, maybe, although i see less of an opportunity for him) to not seem distracted or absentminded while rachel was incapacitated, but the script is pretty straightforward with their dialogue about it. the fact that she comes up a few more times in the episode (e.g., harvey telling mike to tell her to take the day off tomorrow) indicates to me that we're at least supposed to remember that she's in a tough spot, and i guess maybe feel bad for her, but the actual act of her fainting and the hospitalization are so fleeting that i really can't be bothered to keep it in mind.

i think you're onto something there. between her kissing logan and everyone falling all over themselves to convince mike that he needs to forgive her and also she feels really bad so get the hell over it (and did she even really do anything wrong in the first place because remember that time she found out mike and tess had slept together when mike and rachel weren't even a couple which really was just as bad so what right does he have to be mad at her), and her fainting from overwork (although let's be real, that was just a plot device to get mike and harvey back together), the season does certainly twist itself into knots to make her seem sympathetic on paper. except for the part where, as usual, nothing has any consequences; mike takes her back with relatively little fallout, and her fainting and apparently being overworked is never brought up again, so. maybe it wasn't that big of a deal after all.
