There's an extended, better quality promo out and I clipped RB's scene (three seconds :-)) to screencap. It's definitely him and when Gibbs grabs him you can see the visitor's pass so it can't be Tony. Which is a relief; I can't imagine Gibbs ever being this violent with a team member -- the glass on the window gets cracked, for heaven's sake.
A few, still fuzzy, screencaps under the cut.
