Ok, stuff happens, and the Sweepers decided to help Chronos by being decoys on Creed's island while Chronos infiltrate Creed's homebase.
BUT the most important thing that happened in episode 18 is that we FINALLY get to see Eve fight at her max against that kid Leon. Anyone one who's been dying to see Eve fight, this episode certainly delivers it!
And most of the episode dealt with more fighting against Creed's flunkies. Though I have to say, they're really setting up for the final ultimate battle against Creed himself (which obviously Train is going to face). Exciting stuff!
