sam shows mary how google works and he’s like “you can look up anything!” and mary types in like “shoe” and “gun” and idk “kansas” and then sam’s like “and you can look up people! look” and he types in “sam winchester” and then he SLAMS the laptop shut when the results load cause he briefly forgot he was a serial killer
one of my favorite cas headcanons is that he doesn’t really have a concept of what’s “supernatural” and what isn’t – he just knows what exists – so dean’s like, ok babe we’re about to interact with some of sam’s new Normal Friends so don’t talk about anything magical or paranormal they don’t know is really out there and cas nods like he totally gets it but then fifteen minutes later is frantically googling “are bears real” on his phone
god. remember when rowena came to sam and got down low to the ground next to him spoke sweetly(ish) to him and started stroking and squeezing and coaxing the blood out of his arm while he gasped and his eyelids fluttered and then. she disappeared because it was a hallucination. sam literally made all of that up in his own head.
