User blog comment:Reverse Vampire/What are you hoping to see in the Yellow trailer?/@comment-9464517-20130513215955

I just thought of something. All the enemies in the trailers so far have been unintelligent or at least appealing mainly to primal instincts. The wolves in the Red trailer; the huge clunky suit of armour in the White trailer; the robots in the Black one...

How about this: in the final trailer, the adversary is not a stupid or reckless being but someone cold, cunning and heartless. Maybe a human, maybe a demon. Just for a bit of variance.
