And last weeks one where tony took pics of the other guys sister and then set him up wasn't disturbing? It's called drama - every now and again a writer writes something which ordinarilly wouldn't enter your mind, something which makes you think, makes your toes curl, or otherwise gets your attention, and this was one of those moments.
He looked trasumatised because he cared for his sister and was afraid she was going to die. He didn't know the drugs were (as the doctor said) clean prescription drugs and not something got on the streets. To me it was pretty obvious nothing did happen (she was still fully dressed after all) and after he begged, the other's just left him alone.
