Revelation at the end? -spoilers-
Brian is revealed to be a murderer, not a shrink. Fine, coulda seen that coming.
However, he mentions 'the newspaper clippings', and something about someone being bait, Mick then says he played the others - other than lying about who he was - how?
It seemed like it was supposed to be some huge shock, but given his self-preservation fixation, him being a killer rather than a shrink wasn't really.
