who cooks normally?: Stiles. Kenzi can’t cook, and he likes the house still standing.
how often do they fight?: Not so often now that they are together. There was a time when all they WOULD DO was fight, back when they wanted to be with each other but couldn’t admit as much. They still have little snits, but they are quickly resolved with lots of kisses and cuddling.
what do they do when they’re away from each other?: Kenzi needs some time for herself to be able to snitch stuff and to help out with Bo and her stuff. Stiles needs alone time to run his secret web business and to handle pack things.
nicknames for each other?: Stiles calls her Kenz, and then she has a medley of half insulting/half endearing nicknames for him.
who is more likely to pay for dinner?: Stiles pays more often, but it’s closer to 50/50 than anything else.
who steals the covers at night?: KENZI! Stiles normally ends up with a tiny little corner of the blanket and whines about it. Kenzi is tiny! She can’t possibly need that much covers.
what would they get each other for gifts?: Stiles tried getting her big ticket items when they first started dating, but it didn’t fly. Now they are more likely to trade small tokens rather than huge presents. Oddly enough, for them information is one of the best things the other can give them. For two people who don’t trust easily, it says something when they can tell each other little secrets. It’s a comforting feeling, knowing that they have someone to confide in.
who kissed who first?: Even they don’t know. It was in the middle of a huge fight, or more accurately, a smaller fight inside the larger overreaching fight that they found themselves in once Stiles started dating Lydia. By that point he’d broken up with her, but Kenzi’s pride was too wounded to let things go back to the way they were before, and Stiles was too busy being upset she was spending so much time with Derek. They both moved to each other at the same time, although he says she kissed him and she says he kissed her. Both can agree it was fantastic.
who made the first move?: That depends heavily on what you think the first move was. They fell asleep watching too many movies cuddled up together for it to be perfectly platonic, but for all their touching and glancing and teasing, neither of them would have classified any of it as a ‘first move’.
who remembers things?: Stiles. His mind is better with remembering, but that’s not to say that Kenzi can’t hold up her end. There is very little he actually manages to get away with.
who started the relationship?: Stiles was the first to call her his girlfriend, but the relationship itself was something they both wanted and started together. He’s just more comfortable with labels than she ever could be.
who cusses more?: Kenzi. Although that’s not to say that Stiles doesn’t. And it’s also assuming that ‘oh my god’ doesn’t count, because if it did, Stiles would outrun her by a landslide through sheer numbers.
what would they do if the other one was hurt?: Stiles would make sure that whoever hurt her wasn’t around to ever do it again and then sit around and blame himself for not being there to protect her and get angry with her for not being more careful. Kenzi would make sure he was going to live and then handle the situation like the badass she is.
