Headcanon: Mike Stamford wasn't in season 2&3 because he will only come back in season 5 when John is in a relationship with Sherlock and talks to Mike and says "I'm thinking about marriage." And Mike responds with "You're the second to say that to me today." And John will ask "Who was the first?" And cut to Sherlock buying an engagement ring. Or A perfect proposal between boys

Don't imagine them all hanging out and when Dean finally leaves them alone for five minutes Sam trying to explain to Cas that this isn't real and Cas saying "I know." (continues inside)

If only he could get Dean to think of him as anything other than a fare...
