Kit-

-Refers to the person she falls for as "her/my sweetie"

-playful and cuddly, not a good match for people who don't like to be touched because she WILL forget to give them space.

-not opposed to murder. Or cannibalism.

-EXTREMELY deadly in almost any situation she feels she needs to be, usually pretty efficient about it but will play some cat and mouse if she's feeling particularly vicious for whatever reason.

Forrest-

-doesn't use a nickname, but refers to the person he falls for with a gentleness, like even the words need to be treated carefully and sweetly. It's subtle enough that only people who know him well would notice it.

-kinda sullen, with pops of a scrappiness here and there.

-explicitly does not want to be like his father, but upon falling in love is... kinda fighting a losing battle.

(you know how Alan is attrected to human decency)

I don't actually put that much stock into love languages tbh, I feel like the best way to give a ship chemistry is to use most of (if not all of) them. That saiiiid if i must, Kit is very Physical Affection, and Forrest leans more Quality Time. They're both a bit Acts of service-y, Kits more about openly complimenting than Forrest (I feel like Forrest kinda locks up when he has to be honest about how much he likes people lmao), and they both give gifts by kinda just leaving them in a conspicuous place where their person would See It. Like cats.

Kit likes cute people given her brain this a wider net than you'd expect and wants to protect and dote on someone and maybe get a little taken care of in return. I think she sees her parents' (baseline) relationship as quite romantic tbh, and doesn't really understand why her mom was Like That.

Forrest is in general more insecure than Kit.

I think Kit worries her sweetie is gonna be a little bugged out by how aggressive and tall and strong she is. Intimidated or scared.
