S14 ep idea: the whole ep is just Sam’s reactions to anything Dean and Cas (who are now canonically together) do/say. There’s a whole scene of Sam covering his ears, playing loud music and scrambling to find the keys to the car. “I love you guys and I’m so happy you got your act together, but please, be a bit more considerate you’re not the only ones in the bunker”.
OK but only if meanwhile Dean and Cas are totally useless at the hunt because they’re so all over each other and Sam is a badass hunter and does it all himself because he’s super cool and awesome because I am not here for Sam just being on the sidelines - Sam being ridiculously awesome at hunting cos the other two are goodly-eyes-ing each other would be hilarious tho :P
