one night matt was out in patrol and got his head hit so bad he woke up with (temporary) amnesia the next morning (he still won the fight of course).
so matt wakes up and he's just lying in bed when he realises that by the sun (he can tell about what time is it by how the sun feels in his skin) that he's probably late for class and starts panicking because:
c) he can't miss too many classes after almost flunking out of college
f) where's his phone? he can feel some kind of electronic thing but he needs his phone with the keyboard and stuff
g) seriously, where is he?
Meanwhile, foggy and karen are getting worried because matt is late even by matt's standard so they decided to go to matt's apartment just to check in on him.
so they go and open the door with one of their spare keys, matt's hearing all of this from the bedroom and he's now panicking because the homeowner is here but also he's relieved because the homeowner is here and now he'll finally get some answers.
so matt gets up in his boxers and just cautiously walks to what seems to be the living room and realises a guy who smells and overall feels like foggy (but with something different) and a woman are right in front of him.
long story short, foggy's confused but plays along and tells a white lie "matt, the professor sent an email last night saying that today's class is cancelled, didn't you check your email?" to get matt to stay there and he calls claire to check on him and claire tells them it's just temporary amnesia he'll recover pretty soon.
at this point karen and foggy are relieved that he's overall okay and he'll be back to normal soon so after talking it over they decide to tell matt pretty much everything and then have some fun because by the time karen met matt, he was a lot more serious so karen not knowing goofy college/law school matt felt like a crime.
the conversation with matt went well, he believed them or at least acted like he believed them after they showed him so proof, eventually they just ended up talking about whatever when foggy just freezes and turns to matt "i need you to answer a question" "sure" "but like really answer it, you have to tell me the truth" "okay...?" "all those times we went out drinking... did you really do those handstands or did i hallucinate?" karen bursts out laughing and matt has a hint of a smirk on his face as he says "well i couldn't possibly do that, i'm blind remember?" which just sends chills through foggy's spine because that's exactly the answer matt's been giving him for the last 10 years or so.
also, because they didn't mention matt and karen dated at some point matt started hitting on karen "are you flirting with me, murdock?" "yeah, although if you had to ask i guess i'm not doing a really good job at it" that's when karen and foggy looked at each other and started laughing like maniacs, once they recovered and were able to breath normally again they broke the news to him "you already dated her for a bit buddy, a couple of years ago, which you totally blew up by the way" "yeah, there's no way i'll fall for that again, sorry matt" (which is kind of a lie because in her opinion if "normal" matt is easy to fall for then this version of matt is just irresistible, a lot more open and goofy and a lot less likely to push you out of his life).
there's more but idk if anyone would like to read it tbh
