saisai-chan:

headcanon: Soos calls Stan “Mr. Pines” to be respectful, but also because “Stan” sounds really close to “Dad” and Soos is afraid he’ll accidentally call Stanley “Dad” one day, so he sticks to Mr. Pines

secondary headcanon: when Stan leaves with Ford, Soos finally says “You know, I always, uh… kinda saw you as a father figure… Mr. Pines. Um.”

“I know, Soos. And hey, uh, call me Stan from now on. I ain’t your boss anymore, you know.”

“O-oh, okay Mr. Pin–! No, wait, I mean Dad, no uh, Dan, no no, I-I, uh, I mean Stan! Yeah, Stan!! Hahaha…”

Stan pats him on the back, saying “It’s okay, Soos. I understand.” they hug for a moment.

they soon separate, and Stan pats Soos on the arm again. “See ya ‘round, Soos.” Stan starts walking towards his waiting brother. before reaching Ford, he hears a  trong voice trail off into a whisper say, “See ya ‘round… Dad.”

Stan smiles.
