"Brothers & Sisters" scoop: Just what is Chad Barry up to?

Jason Lewis as Chad Barry 

Ever since Michael Ausiello leaked word that Chad Barry (Jason Lewis) would be popping up for an episode of Brothers & Sisters, tongues have been wagging about just what is up with that? Is Kevin going to return to his "can't commit" persona and cheat on Scotty (Luke Macfarlane)? Has Chad reappeared with some nefarious plot to break up our favorite gay couple? Is Chad now an ex-gay who has come to convert both Kevin and Scotty?

I'd did some digging and learned some very interesting details!

Kevin is not going to cheat on Scotty, and Chad did not turn up to seduce Scotty thereby causing trouble in the Walker/Wandell household. But that doesn't mean that sex won't be central to what goes on between the three men. Whatever takes place (and I can't say too much) does cause Kevin and Scotty to have a serious discussion about an issue dealt with by many gay men in relationships.

Kevin: What do you think about it?
Scotty: I asked you first!

Any guesses as to exactly what goes down?
