some kailex headcanons !! (bc uhhh do i really need to have a justification??)
Obviously Akarnae's Resident Power Couple TM
They're both really socially intimidating and are friends with a lot of popular people, but don't... really participate in a lot of teenage rituals, especially when there's masses of strangers? Chances are, if they're at a party, they're scaling a building together and hoping their friends haven't fallen down a pit or something in their absence
Kaiden was the first person to show Alex how to properly throw knives, mostly because it was a skill neither Karter or Niyx ever bothered with her
Similarly, she taught him how to drive a car when she took him to Freya one summer (probably manual too bc he's a multitalented prick)
They do spend a lot of time together, but most people don't realise a lot of it is in comfortable silence. Alex has a tendency to fall asleep on him, not that he's complaining.
In general, Alex has a fairly disrupted sleep pattern because of nightmares and Kaiden is insomniac, so they tend to spend a fair few hours stargazing or night swimming.
Kaiden's the one who says 'I love you' first.
He rarely gets intoxicated, but when he does, he's a sappy drunk who suddenly loves everyone, and for the love of god, do NOT get him started on Alex. You'll be listening to him ramble on about her until four in the morning.
She's one of the few people who not only know about Kaiden's gift but are able to see past it to who he is, so he slowly gets more comfortable with getting to be excited about acquiring a new gift and actually sharing it with another person, that being her.
Alex is definitely a Swiftie and will absolutely belt out lyrics from time to time. (You bet she loses her mind with the release of the Taylor's Version albums and probably makes a bad "Hey Kaid, can you break up with me for about 2 hours so I can listen to this new album by a Freyan artist?" joke at some point)
Alex never wraps her hands for hand to hand combat and it drives Kaiden insane, so he always does it for her before classes/practise spars (so many knuckle kisses and the occasional cheeky ass smack)
Tbh, they probably butt heads every now and then because Kaiden tries to be a gentleman and Alex has an independency streak, and it doesn't work out well for them.
Alex is one of those girls who LOVES having multiple piercings -- but also absolutely hates needles, so guess who holds her hand when she's getting a new piercing done
(She almost breaks Kaiden's hand, on multiple occasions)
During one of the numerous visits to the piercer's, Kaiden gets quite familiar with all of the tattoo designs plastering on the walls, and decides to get one of his own. (Personally, I like to HC his late mum's name was floral related, so he gets a half sleeve of whatever flower.)
I've seen a lot of theories for when/if they have kids after a few years in the fandom, and whilst I have mixed feelings about Applying Heteronormative Expectations To Comfort Characters, @azymondias05 's headcanon of them adopting kids (Leo!!) makes me practically froth at the mouth bc I love that concept so much idk what it is about it
