1. Give me your best schmoop Sam/Dean! Hugs, hair stroking, doesn't have to be wincest, just some nice closeness because its nice and sunny outside and I'm feeling mushy today. Something to make the smile I have on my face crack into a grin. Something just nice and 'awwww, that's so cute I wanna cry.' I don't know what I'm looking for specifially so throw anything cute at me.

2. Sam and Cas begin to have a profound bond of their own, wink wink nudg nudge. And they don't tell Dean right away or he doesn't know because he's oblivious, and then suddenly he does know and he's shocked, in a good way or bad. Can evolve into Sam/Cas/Dean thing, he can be really happy for them. Or he can be super jelous, or really unsupportive. Any reaction, just as long as he's not aware until Sam and Cas are quite far into their relationship. 

Thanks peeps!
