Apparently reporting my mental screensaver thoughts about Destiel got me 1000 notes overnight and I reached a modest follower milestone so now I feel obligated to do something nice for you lovely people. I spent some serious time and energy coming up with a totally unscientific unresearched aside from a single 2am Google search way Dean n Cas could & would literally get married without breaking the unresolved sexual tension. Treat it as a vague chronological follow up to that post if you like.
Sam finally boiled over the first time Claire came to stay in the Bunker after the unexplained marriage incident.
Specifically, when she paused on her way to the kitchen with her progress blocked by bowed legs splayed across the library - where Dean was sitting at a ridiculous angle with his back almost turned all the way to the table to avoid catching Cas’s eye.
“Move it, Pops,” Claire said, and Dean casually scooted his legs in to grant her passage.
She’d barely stepped out of line of sight when Sam slammed his hand down on the table, making Dean and Cas both jump.
“I don’t buy it.”
“What?” Dean asked, acting wholly innocent, while Cas just tipped his head and squinted at Sam, like they honestly hadn’t noticed this was going on.
“This whole marriage thing. No one gets accidentally married, and if they did, it’s in Vegas and there’s a divorce right after.”
“You should know,” Dean snorted.
“That’s another thing! I managed to invite you to my sketchy love potion Vegas wedding, and then you get hitched to our closest friend and I don’t even find out until I see you’re both wearing rings? And all I get is an ‘oh yeah, I married Cas I guess’ when I point it out? It’s got to be nearly your anniversary and I still don’t know what’s going on. What gives?”
