Mainly, these pictures (nsfw-ish) are to blame, plus the episode this week, which lead to this tweet and Twitter thread. Also yay for a new pairing I'm writing (Derek/Parrish). So yeah, enjoy! 

Derek always knew that the Sheriff’s new deputy looked familiar, but he could never place him. He knew he’d seen that face before, those eyes, those lips, that smile, but with all the crap he’s been through the last few years, smiles and faces tend to blur together or become bloody and vacant. It doesn’t help that he only knows him as Deputy Parrish and only ever sees him in his uniform.

So when he gets a look at the second list Lydia cracked and sees the first name of Deputy Parrish on the list, it all comes flooding back to him. He knows exactly where he’s seen him before and why he’s on the list. No wonder he could never remember before. It’s because when he had known him, he had significantly less clothing and went by Jailbait Jordan and answered to various other nicknames that make Derek’s ears turn red.

Parrish is on the list not because he’s a supernatural creature, per say, but because he’s well acquainted with the supernatural world and just how tight to squeeze or hard to suck or what to say or smell like or how to move to really get a werewolf going. The more Derek thinks about it and remembers all those times he went to the werewolf-only strip club, the hotter he gets and he feels like he’s going to suffocate.
