AliveHales Headcanon: Derek has no problem with teasing and bantering but he's a bit sensitive underneath his growls. His family in general and his sisters in particular frequently honestly hurt his feelings. Cora doesn't know when to stop and Laura has a knack for going for his emotional jugular. He hates feeling embarrassed especially in public but he's resigned to it because protesting or asking them to stop makes it worse. They don't mean to be hurtful but it doesn't bother them so (1/?)
they don’t get why it bothers him. This goes on until Cora brings Stiles home one day. Stiles has been crushing on Cora’s hot older brother for ages but Derek always avoids him (Derek is avoiding him because he KNOWS his sisters will give him shit in front of the cute guy and he’d rather not thanks). Cora invites Stiles to stay for dinner and at first it’s all good but the teasing starts and it’s fine but Stiles notices how Derek sort of shuts down after something Laura says (2/3)
and Stiles mouths off and knocks Laura down a few pegs in Derek’s defense. He is more than willing to use his sarcastic nature in defense of the hot marshmallow sitting across from him. Stiles likes it when Derek’s eyes light up not when they go guarded. And that’s the story of how Derek pretty much falls in love with him on the spot. It’s also the story of how Stiles appoints himself Derek’s emotional protector and you do not want to get on his bad side about that. (3/3)
*wipes tear* stiles being protective of derek is one of my absolute favorite things, bless this entire thing.
i can totally see laura and cora taking it a step or two too far with teasing derek (i’ve got four siblings, it does happen a lot during the sibling bantering and apologies don’t always happen, just more teasing that ends up being unintentionally hurtful) and derek being quiet about it, not fighting it and just waiting for it to stop instead of asking for it to.
and stiles appointing himself derek’s emotional protector, i’m !!!!!! sign me the fuck up, pal. i need stiles ripping people who are mean to derek a new asshole and derek blushing and smiling while it happens cause no one has done that for him before.
just… stiles making derek feel loved is what i’m here for ;;
