An intense episode featuring a confrontation on a train, with high potential for epic scenes, but the setting wasn't used to its full potential. On the other hand, I couldn't help but notice the noticeably poorly rendered 3D effects and the awful texture of the enemy's dagger. I like the dual focus of the episode: while Waver and Gray deal with a murder and a secret enemy on a train; Reines, Livia, and Sisigou are investigating other matters on their own. A good episode overall, it's a shame about the drop in animation quality.
