Good episode. Not as strong as the first two, but still good enough.
"Cowboy" is back in the game. The story of Frankenstein's "first born" is revealed. So he came back for his creator to demand a female mate. He wants something to love ... well, that might be a delicate task for Frankenstein.
One thing I didn't quite get. What was it with the wolves at the zoo? I hope, we'll get that explained in future episodes.
I think now the series set-up is ready, so there'll be more action and development from now on (more like in the pilot, which was very well done to make me want more).
