The stakes have now risen for this show. With so much going on, the writers/directors just handle it so easily, distributing focus on each of the main and supporting character with refreshing equality.
The main plot here is again taken the to the next level with an invisible predator like demon. The solution to seek and trap the target is truly the best example so far. Absolutely loved it! I liked how they the Katie, Andi and Sam triangle took a little bit of a backburner in this episode and how it has been setup for a real blow-out in forthcoming shows. This will be very interesting to see how Sam handles a possibly exploding devils spawn (very cute too!)
The first subplot is that the guys move into their own apartment causing them more issue. Indeed, how much so when they discover who is living next to them!
