One of the main characters has a cybernetic, prosthetic arm that his highly advanced and works like a real arm. (I think she lost it when she went to "the other side." a parallel universe similar to our own. She lost it in the process of coming back, I think - could be wrong...) I screamed "Automail!!" the first time I saw it! She always wears a glove, too!
Then in the current episode, whilst I was actually trying to figure out if the actor playing a cop was Travis Willingham (it wasn't), that same cop takes a brief case from a someone and an immediate reaction occurs, spreading up his arm from the handle, changing his entire body until, moments later, he explodes. A human bomb! Later on, the FBI agents discussing the incident note that while a bomb clearly had gone off, there was no residue of explosive found. Of course, not, I thought. The human body contains all the componants needed for a basic bomb...
Just makes me wonder if Abrams (who also made "Alias," another favorite of mine), wasn't reading or watching FMA and thought, "You know - those are really good ideas..."
