It's not so much "stop being angry" as "don't shut me out completely." And it would probably help if c!Stephen didn't have the same reaction to everything, up to and including "Jon will not apologize to Geraldo"...

L!Stephen is taking charge of the situation. This is a Good Thing. And it's the instant validation from the people around him that gives him the confidence to keep it up.

This one will work around to happy things eventually!
