(and more headcanons since i guess i can’t stop)

magnus is 100% the type of person who has a song for every occasion. alec knows almost none of them, but you’ll still catch him singing the lyrics he’s learned from magnus sometimes. he doesn’t have nearly the same sense of timing that magnus does though.

after alec leaves sometimes, magnus will sing the line “i’m outta my head hopelessly devoted to you” at the door behind him and alec catches him at it once but doesn’t let him know until he surprises him with a (terrible) rendition of the full song with the lyrics rewritten to be positive on what would have been his anniversary with lydia, if magnus hadn’t asked just once more. this is excellent timing. magnus cries.

magnus introduces alec to pop music. and to sex music – both the concept and his own playlist. alec thinks that maybe jace wasn’t always wrong about getting more familiar with the mundane world but he doesn’t regret putting it off til now for a second.

in addition to saying his full name as though it were the only word that’s ever mattered as a term of endearment, magnus calls alec “dear heart.” alec loves this more than anything.

magnus finds alec’s enthusiastic inexperience to be devastatingly charming in bed.

it helps also that alec takes direction well. extremely well.

alec, for his part, loves direction. loves knowing without doubt how to make magnus feel good. loves making magnus feel good. also he learns so much. soooooooo much. he had no idea there were so many positions for this type of thing. so many uses for hands and tongues. so many reasons to laugh in breathless, boundless joy while gettin’ jiggy with it (a phrase magnus bans him from using, can hardly believe he even uttered in the first place).

alec likes whiskey sours and pretty much no other kind of alcoholic beverage. (he can be talked into amaretto sours and will take orange juice in either – the latter is how magnus excuses their occasional breakfast drinking: “it’s just a variation on the mimosa theme, alexander.” he looks up at alec from over his own full glass, coy in full effect. “drink with me.” alec’s weak for this and he’s fine with it.) it takes them an entire day devoted to finding alec a drink he likes to discover it and as soon as magnus sees alec with it, he thinks “duh” and never offers him vodka anything ever again.

alec does get righteously drunk on vodka once – straight vodka, on his own. something goes bad at the institute – magnus never does find out quite what – and neither izzy nor jace are speaking to alec, for their own reasons, and alec shows up at magnus’ loft drunk off his ass. he chose vodka because it seemed faster and painful – magnus sees him gazing at his raw hand on the fire escape – and he pukes over and over and over again with magnus leaning over him feeling murderous towards everyone who had anything to do with alec feeling this way. they get through the night in magnus’ bathroom, alec telling him painful, incoherent things the whole time. magnus does not cure his hangover the next day, though he wants to, because he does not do things to alec’s body without permission – bar instances of immediate threat to alec’s life or someone else’s – and he does not have permission.

(there’s one particular story that alec tells about how proud his mother was of him taking a punishment doled out when he was a child, for being too good at something – “no one even knew it hurt, i couldn’t lay on my back for a week, but no one knew,” he tells magnus proudly. magnus thinks seriously that he’s going to be the one puking now. he also thinks that someone should save all four of maryse’s kids from her and save her from herself if that’s at all possible at this point. he thinks he’s gonna have to not be in a room with her for a very long time.)

after that alec decides that talking to magnus while sober is always a better dealing-with-shit strategy if he doesn’t want to wake up to his boyfriend insisting that he unpack some of the emotional issues he accidentally spilled to him and holding an overwhelming plate of the world’s fluffiest pancakes, saying, “you’re gonna wanna eat sooner rather than later, alec. yes i know this sucks, dear heart, but trust me. also, try to drink your body weight in water, starting right now.”

magnus has little to no concept of alec being just as gone on him as he is on alec and when alec figures that out, he spends a lot more time staring lovingly at magnus when they talk. he also gets a lot more handsy in public and magnus has had to pull him off of more than a few people who make snide comments about a warlock with a shadowhunter. soon, the spell where he pulls alec back by the fist is so familiar to them both that alec routinely takes it into a full backwards somersault and pops up on his feet at magnus’ side, where magnus has stepped to give him room to stick the landing.

magnus has a thing for ’90s bollywood. alec is still trying to figure out which songs are imaginary and which are actually happening in the story. he learns how to say “i love you” in hindi though and uses it a lot. he also uses the pet names he picks up, though he hasn’t quite grasped the pronunciations for most of them yet. he’s trying and honestly, most of the time magnus can’t hear it past the pounding of his pulse in his ears anyway because alec doesn’t do terms of endearment lightly so magnus doesn’t hear them lightly.

the first time magnus saw alec without his pants on he said, “boxer briefs, thank god.”

he followed this up by licking just above the waistband where it rested on alec’s stomach, hands on alec’s hips. this set off the biggest stutter spell in alec to date, which only calmed down after magnus kissed him on the mouth three times, i.e. once he had no choice but to use all his air for recovery.

magnus buys a punching bag for his loft. for shirtless alec reasons.

using it is alec’s version of “come hither” at least half the time.

they get caught fooling around in alec’s room at the institute – by clary, of course, because she, like jace, has no concept of knocking – exactly once before they never do that again. jace actually has to pay raj off to get him to stop talking about it. raj was passing by when clary spooked them and they started grabbing clothes and pulling on the wrong ones (magnus too frazzled to magick them clothed again which has never happened in his life but being intimate with alec just. throws him the fuck off his game) and he regards it as the best moment of his life. alec and magnus regard it as one of their worst. although that thing with his tongue that alec had figured out how to do just before that moment was pretty special, in magnus’ opinion.
