I always felt bad that Justin's parting words to Ethan had to be about Brian. That whole thing should have been about Ethan and Justin and not Ethan shoving Brian down Justin's throat to deflect what he did.
I also agree with Brian and Justin keeping their hands or lips to themselves.It would have been really disappointing to see both characters take on something like that. I also don't think Brian would allow himself to become "The Other Man" even if it meant having what he really wanted.
