FBI agent did find the mechanic hand covered in skin. Add his knowledge of synthetic blood and he gets the idea.
Well, some things in this series better NOT be taken with Serious thinking :p You will enjoy it better if you don't :p
I don't lash at things immediately, just few things here and there lately, since plot does pick up. Show still being mediocre, and suffers from being TV show with TV budget, which really does hurt action, and what they trying to do. Also, it seems its afraid to take risks, unlike 24, which can be much more brutal in few areas.
