I have seen summaries for AUs where the older/younger sibling position were reversed. That would be interesting to think about. Would it make Sam more rebellious, or would it mitigate it? Would older Sam's reservations change the nature of John's investment in Dean's loyalty? In all universes, the brothers would just yin-yang no matter how you cut them; they shape each other too much.

lol where is Uno these days? I miss her. OMG LUCIFER AND MICHAEL PUNDITS, I love it. Too many times, Cas has had to shoot the camera and strained smile saying, "And now for a word from our sponsors!" as Michael and Lucifer continue to hurl invectives at each other in the background.

I will reply to the prompt in another comment. :D
