Tommy Walker

There's going to be an upcoming episode -- a two-parter -- on 'Brothers and Sisters' that will boldly go somewhere it hasn't gone before (at least not in any detail). And when they do, we may be seeing teen heart throb Joe Jonas on 'Brothers and Sisters' as Tommy Walker. That's the Balthazar Getty role.

ABC hasn't confirmed the Jonas casting, but it would make sense. Look at how much alike they are? But there's still a question about acting. Is Joe Jonas able to make us believe that he's a young Tommy Walker?
