OH HOW DID YOU KNOW IT’S JUST WHAT I’VE ALWAYS WANTED! 8D
who cooks normally?: They usually cook together… Cloud gets nervous cooking on his own (he’s not very experienced at it, neither is Vincent really but he tends to follow recipes better) and he doesn’t like not helping when Vincent does… plus he’s hoping to get better with the extra experience.
how often do they fight?: Very rarely, they’re like-minded and don’t often disagree in the first place, but when they do they usually catch themselves before they get too far and just take some quiet time alone to think things over before discussing more rationally. They’re very forgiving of one-another so even if it does come to shouting and storming off it doesn’t really harm the relationship at all.
what do they do when they’re away from each other?: Vincent is pretty meticulous about keeping his guns in tip-top shape… he’s always cleaning and polishing and adjusting, he’s very detail-oriented with those things… when he does it around Cloud it kind of drives Cloud nuts because of how nitpicky he is, so he tries to hold off on this type of work until Cloud is out on a delivery. When Vincent is not around Cloud is just a lazy couch potato, he probably watches TV for 12 hours a day in his snuggie (which he hides somewhere hard to find so Vincent will never know he has it) eating cookies and tea (he acquired a taste for it after travelling too long with Cid).
nicknames for each other?: Cloud uses ‘Vince’ but only when they’re in private. Vincent just sticks with Cloud.
who is more likely to pay for dinner?: Cloud because he’s probably got more money from his business… unless you figure Vincent’s old ShinRa bank account was never closed and has been slowly gathering interest for over 30 years, in which case they’re freaking rich and Vincent probably does.
who steals the covers at night?: Vincent, because Cloud’s used to being cold all the time (I mean he grew up in Nibelheim…) meanwhile Vincent’s kind of a weenie about it. Cloud usually doesn’t even notice.
what would they get each other for gifts?: Cloud gets Vincent clothes because Vincent has 0 modern fashion sense and as we all know Cloud’s is freaking awesome… if he didn’t Vincent would just wear suits all the time… which Cloud doesn’t mind because Vincent looks damn good in them, but there’s some places you just don’t go to in a suit (Gold Saucer, Marlene’s birthday parties, etc.). Vincent varies between getting Cloud extremely practical things (oil and other tools for Fenrir’s upkeep) or extremely unnecessary, romantic things (flowers and chocolate and candles and stuff) because Vincent is both of those kinds of guy.
who remembers things?: Vincent. Cloud keeps a ledger to run his business but even with it he’s usually too scattered thinking about delivery routes and fuel costs and things to keep track of times and dates and whether or not they need to get groceries and stuff.
who cusses more?: Cloud, definitely. Growing up in a poor rural town and then joining the infantry in Midgar he’s heard it all and doesn’t hesitate to use it… not as frequently as Cid of course. Vincent still has kind of an old-fashioned mentality about that - he doesn’t get offended when others swear, but he doesn’t do it much himself.
what would they do if the other one was hurt?: If Vincent is hurt by something or someone Cloud’s priority (after getting Vincent to safety) is vengeance. He’s useless in the case of illness or any hurt without a specific cause… he’ll worry and pace and drive himself crazy not knowing what to do. In general Cloud feels somewhat indebted to Vincent in this respect, for saving him after the fight with Kadaj and because he wasn’t able to contribute much to the war effort against Deepground. Vincent, meanwhile, operates under the assumption that Cloud can handle himself in battle/against a physical opponent (unless it’s obvious he cannot, at which point he’ll step in to assist), but dotes on him when he’s sick or sad. In general Vincent is very patient with Cloud (and anyone) when they are ill or in pain, he’ll stay by his side, help him get around, do things for him if asked (or if not asked) just being an anchor and a comfort.
who kissed who first?: Vincent definitely kissed Cloud first. Cloud doesn’t know the first thing about kissing and wouldn’t have taken that chance.
who made the first move?: With these two the first ‘move’ would probably come after the start of the relationship… in which case I would think also Vincent, because romance is really not Cloud’s forte (Cloud gets flustered just flirting).
who started the relationship?: This one would be Cloud. Because Vincent has pretty shitty initiative. It took a long-ass time anyway and probably went something like ‘Hey everyone else has already paired off and since we’re having such crap luck with that why don’t we just be with eachother’ and that was that. After their relationship was established Vincent felt more comfortable driving it forward… he just needed Cloud to take the first step.
