I'm a fan of David Zayas, best known as Angel on Dexter, so it was cool to see him pop up on Grimm. Unfortunately, his role here was barely there. The upside is that his character was put in jail and not killed off. So, there is that off chance that he could return later in future episodes. His clan seems to have a rich background that has been terrorizing people for a long time. So, it is possible they are gearing up for some kind of revolt between the townspeople and his own kind.
