Beatrix's backstory was much needed and animated very well. I think controlling the elemental monsters is a very lucky plan for the loyalists, but their plan is good. I thought the focus on Cole was a good idea for this episode as it helped bring him into the season story. The reflections we see with Lloyd are also really good in this episode, as we see the problems he has previously gone through. Learning from mistakes is a very good theme. The action in this episode is also good, as the different stories are fighting their specific villains. The Beatrix vs Cole fight was really good. I liked the ending scene but I didn't understand how Arin felt the elemental presence. Score: 9.1/10
