Okay but like, I just imagine Alec spending the entire time going out of his mind wanting to crawl out of his skin and he all but forces himself to go back to Magnus to check on him, fully expecting to be turned away at the door. And when Magnus opens, he’s not wearing makeup, washed out sweats and maybe one of Alec’s really old tshirts. His hair is combed down and he looks really unsure and can’t really meet Alec’s eyes. And that’s when it clicks for Alec that Magnus probably spiralled because if he hasn’t put in the effort to look fine, then it’s really really bad. So he almost collapses on the spot when it hits him “I did that to him, I caused him enough pain that he can’t even be bothered oh no oh fuck” so he kinda leans against the door frame to hold himself up and Magnus can see how badly it’s affecting Alec to see him this broken down and “oh no I’m making it worse and we haven’t even said anything no no no” so he tries to smile but it doesn’t reach his eyes and he feels so fake about it but Alec please come inside please don’t leave again so he gestures for Alec to come inside but they both kinda get stuck between the couches and hall just like on their first date but this time it’s so different and they just kinda stand there, looking everywhere but each other not knowing what to do and aaaaaa pain
ok YES tho!!!!!!!!! i was thinking that magnus put on an effort so he could Be Ready And Functional when alec got home but the idea that magnus was just bare faced and in sweatpants miserable is just... aaaa
especially because like usually alec would love it and be so happy to see magnus allowing himself to look imperfect, vulnerable, comfortable around him. but now it just looks like magnus is breaking down and the fact that he can see the guilt in magnus' eyes when he sees alec's face and then the fake smile just makes it even worse. like the worst of both worlds, the misery and the uptightness (thats not a good word but its the only one i can think of)
also god magnus begging alec not to leave again and just WAR FLASHBACKS to the breakup and magnus again feeling so insufficient and like a failure and alec feeling like he keeps hurting and losing the man he loves. but this time he stays but it's awkward and strained and magnus thinks i'm forcing him and alec thinks im making it worse, i can't fix this and it feels just as bad as it did when alec actually left last time. except maybe a little duller because they're both trying so hard to keep it together to support each other
and of course neither wants to be supported and both are stumbling so there's no way either of them can get anywhere. so they just stand there feeling like failures and crumbling deeper into themselves and aaaa
also it just makes magnus feel like The Culprit™ won and he's too weak to deal with this even though it was something so small and simple (alec punched him? he's been through so much worse so many times, this shouldn't even register. it wasn't even actually him, just some other guy controlling his body; magnus should be laughing at how stupid it was) so when did magnus become so fragile? he even looks a mess and he has no idea how to pretend anymore
and again they just crumble into this war of "im sorry"s to each other that are just increasingly frantic until somehow magnus ends up latching himself into alec's arms and they just hug each other fiercely and it's all "i never meant to hurt you" "i should have noticed what was happened" "i shouldnt have left you" "i shouldnt have let you leave" and kissing each other's shoulders a little bit, as much as they can when they're holding each other so tight xbxjxn and apologies that turn into venting and reassurance and it's exactly what they need
and they emerge from the hug better but exhausted so they take a nap together and cuddle and the next day have a better talk about it and what they can do to prevent this sort of spiralling if it ever happens again and it's good for them both 🥺
