immediately begins to shimmy when maroon 5 comes onwell obviously dean does - and castiel isn’t entirely sure what’s going on here, but he thinks it’s cute and maybe dean ropes him into it (30 second dance party in the spn world, aw yeah)
wakes the other up at 3am demanding pancakessee, dean would wake cas up, but that would end disastrously. so that leads to me believing that cas wakes up dean for the pancakes. i’m not sure what the scenario would be. maybe he can’t sleep and he just REALLY wants some pancakes. he had them a few times or once or twice and he just really wants some. so dean makes him the best pancakes he’s ever tasted (never forget dean can cook, guys)
sends the other unsolicited nudesdean does it to castiel all the time. the first time it happens, cas has to ask why he’s being sent the nudes. why would dean do that? and dean is all “you’re supposed to… you just… you know… you enjoy it.” and things get a little awkward because they’re both fucking idiots. but then dean does it again. and again. and again. and it starts flustering castiel and making him feel things and oh gosh, okay.
brags about knowing karate even though they never made it past yellow beltalways dean. my response to this will always be dean. even though castiel has no idea why dean is bragging and knows that dean is a lying liar who lies.
comes to a complete halt outside bakeries/candy shopsdean. but castiel enjoys it because he likes sweets.
blows sarcastic kisses after doing ridiculous shit dean. and castiel never fully reads into the sarcasm, which makes it more frustrating for dean. because cas always does it back to him, but with a more endearing touch, and it makes dean go “for fuck sakes” every time.
killed the guy (also, which hid the body)dean. dean hid the body. him and cas never talked about it again.
wears the least clothing around the housedean. he likes the whole “boxers & a robe” feature. he picked it up from chuck. and cas even mentions that it reminds him of the writer of the winchester gospel. and maybe cas starts doing the same thing once in a while because it seems comfortable - and wow, it really is comfortable. and sam walks in on dean and cas chilling on dean’s bed watching movies and just sitting in robes and boxers. and he just slowly leaves the room.
has icky sentimental moments for no apparent reasondean. castiel loves them. it’s his favourite time of day/week with dean.
