I watched this episode again and I still really enjoyed it. I love how much they were able to fit in during the 21 minutes they had. They gave us backstory on Froakie, information about Mega Evolution, a TR attack, Garchomp's rampage, a few scenes with Serena, Mega Blaziken saving the day and I have to say it all felt REALLY well paced. I was really impressed with how well paced it was. I didn't feel like any scene should have been any longer or shorter than it was. And for the second episode of the season, it was very intense. We usually don't really see the show get this action packed this quickly but this really felt like an episode that would show up later in the series if this was any other saga. I would say the only real problem I had with this episode was how TR was handled here. They were really only here as plot devices, but they did their job in getting Garchomp to rampage. So overall, it was a very strong episode.
