well, the one thing that struck me about that promo is that when Jeffrey says "It think Sabotage happens", it is done in two shots peiced together.
The first is Jeffrey leaning on a manequin saying

I wondered if it was meant to be misleading, because it seems like it would be too easy to guess that it was him.
I also noticed that I dont see that promo on TV anymore.
Vincent is so unbalanced I'd almost guess it was him.
