Lance Reddick is such a strong character as Agent Broyles. This episode puts him a bit more in the forefront as we get more backstory and purpose out of him. I also enjoy getting to know the side characters better, especially in the case of Broyles since he is a majorly important part of Fringe Division and we really don't see much of him beyond administrate duties. The plot for this episode is well done too and is a nice break from the intense main plot of the show, a good little filler episode you could say. I thought the special effects were neat and while the science was still very pseudo, it was an interesting concept. I liked this episode quite a bit and had a good time watching the team work through the mystery with a few spooky and tense scenes thrown in there too.
