The clues from the last episode promo is that there are 3 suspects left. But those arent the ones with the 3 dot tatoo because lets be honets...in the episode they only showed us Smith and Bertram as suspects... the real suspects are the 3 guys that "died" in the explosion (thats what Jane realizes when he found out about partridge at the morgue, he cant trust. he knows that someone will plant evidence or as in Bretts case: eliminate evidence)
In my opinion its clearly Haffner.
If not why would they show a scene (the one at the hospital) where Ray says to Theresa: "one of these days we will have a talk" ??
I think that still something big to be shown and it will come in next week episode.
