Eiffel, 4: Eiffel is surprisingly cuddly when he likes people, so he'll happily share a bed with like, all of his current positive CR. however he is also a flailer and a blanket hog and an oven so really that's on his friends for accepting that
Eiffel, 5: he'd rather give people physical affection than receive, but mostly he's just never had any/many massages before so he wouldn't know what to do with it? but he would enjoy it
Eiffel, 20: oh my god please don't let eiffel near a kitchen, he doesn't even have one in his cabin. he can do basic bitch bachelor food and like, way too many snacks, but he can't cook to save his life. he's fed by the grace of the kitchen staff, and also hakkai and neal
Arthur, 10: i don't think arthur is really ticklish, but he's also extremely touch-starved currently so he's a bit hypersensitive to pretty much any and all touch and is therefore markedly reactive no matter what he gets, so if someone did try and tickle him he would react
Arthur, 24: watch them be passionate about something they care about, or be sincerely curious about the world around them. a lot of his softest moments with John came from john trying to understand poetry, or to apply his curiosity to understanding the world as they explored together
Arthur, 11: arthur gives to others in words of affirmation, and tends to go for extreme eloquence when he does, but he best receives in actions/quality time. he cares about actions way more readily than words, especially since he's got a good bit of religious trauma along the veins of "this was all in god's plan" sort of shit
Arthur, 17: arthur doesn't say anything he doesn't mean, so if someone says "i love you" to him they'll get a shitload of fluster unless he genuinely does love them and can say so back. that list is currently limited to John and Reid, lmao, but willa and sheehan are close contenders to making the list
Eiffel, 15: contrary to popular opinion eiffel cares about being clean. what he doesn't care about is appearances. so he will actively keep on top of hygiene, he does actually wash his hair and take good care of his physical self. it's just that the shitty star wars t-shirts with the faded logo and holes around the collar are also washed regularly
he also had a child so he's not above helping other people with things like grooming/hair/etc, but he also hasn't done it in a while and he may or may not psych himself out of doing it properly
Eiffel, 23: he's charmed by people with big grins and doofy laughs. people who can still express joy sincerely even when they've been through hard times. his bonding moments in canon are always when people are being their authentic selves and not putting on airs or roles
Arthur, 9: oh arthur is super fucking old school, he is consistently embarrassed by public affection unless it's either very subtle or he instigates it himself, at which point he will get flustered and back out almost immediately
(also Eiffel is very adorable. Hakkai fully has a love language based around taking care of other people and has high odds of. like. developing a habit of fixing eiffel's bangs)
it's not but it sure does make it easier
