^Yeah, that was weird. We saw Fusco watching them, but they never wrapped up what happened. Did he arrest the guy or was the gang stopped? Not very well handled, that.
I took Fusco returning to the train station to mean that he took care of the thugs in his own way, however ethically-challenged that way may have been.
So no one knows the reason Caviezel was barely seen this in this episode? I was curious if the actor was taking time off or if the writers just planned it this way. I'm guessing the latter since the Reese getting caught by the FBI arc seems way too much to have been done on the fly to accommodate an absent actor.
