So, the Cortex is appearing every two episodes. I don't know about you, but this pattern is starting to annoy me.
So, the episode was pretty much to establish one thing, Laura is determined to join the Lyoko Warriors. Other than that, we got the introduction of the Ninjas. They remind me of the Wraiths in the Ico video game for some reason. They're nice, it seems finally the Lyoko warriors will have to rethink their ways of dealing with the monsters (because for some reason, I have a feeling the Blok Wall won't appear again).
This episode showed a side of Laura that I really didn't see coming. I thought she would be a bit more intimidated by the whole thing with XANA, but instead she even seems a bit... evil...? I mean, she was called to deal with fixing a virus, and she goes and sees the features of the Supercomputer, and then alters the way the Return to the Past works. It's like you let a friend help with something in your computer and he decides to take a look at your folders without asking and starts meddling with your files (Believe me, this happened to me)
Anyway, the Lyoko Warriors decide to keep Laura at a distance, only recurring to her when absolutely necessary. When Jeremie opens the door of the room to leave, tada! Laura is there and enters the room. I've got to tell you, that look on Aelita's face gives me the shivers.
One thing that annoyed me in this episode is that it implies that Laura is smarter than Jeremie. That will throw the whole show off, as there won't be a reason for Jeremie to even help the team. You can't do that to the main protagonist! (I see Jeremie and Aelita as the two main protagonists of the story, and I didn't really find anything that said otherwise)
As for the acting, nothing to say, really. It seems that everyone has found their way and aren't lost anymore.
Overall, this wasn't a bad episode, and I really don't have an idea of where to change it to make it better. There were just some stuff that annoyed me in this episode.
Well, that was my opinion. What's yours?
