Cactus Fruit Sorbet for Ryker, Neapolitan for Dollar?
Cactus Fruit Sorbet/This shouldn't work but it does headcanon:
Ryker's never been the defiant type. Ever since he was little, Dollar's been throwing hands at anyone who looks at him wrong, and as such, he never felt the need to fight his own battles. Now, with Eric, that's kind of biting him on the ass. Ryker's solution to this is to imagine that Dollar is standing behind him, whispering in his ear. It doesn't deliver him from punishment but it does bring him a modicum of comfort.
Neopolitan/an intimacy vulnerability headcanon:
Dollar's never been in a serious relationship. They've had flings, hookups, one night stands but never officially been a partner. Mostly because they were worried how it would affect Ryker. They never wanted him to feel abandoned or threatened. It was only once they were encouraging him to to attend college that they realised "shit, wait, I'm gonna be all alone." And they decided to tentatively dive into seriously dating. That's why they decided to give Arleen a try.
