This episode sucks, really bad. Personally, from a series like Witch Hunter Robin, you would have been expecting more violence, instead of little Robin bowing to an old man who turns out to be her grandfather.
But there was some intresting parts to this one, which made up for the dissappointment. For example: We finally learn who Robin is (Call her 'The Devil's Child' if you want) and abot Maria. Then, there's Father Julliano, who raised Robin and is revealed to be her Grandfather (No, I'm serious)
And you have the short sceen of Julliano about to stab a baby (Robin) but fails to last-second. Sad, really, but there should have been more action to this episode.
