Judging by the pics, it seemed like a great episode battles were kind of cool, I felt a little bad about Bianca losing but anyway, I'm fine with Kotetsu winning. I think Trip is left, and why should he stay I mean he's not friends with anyone and basically has no reason to stay. The ending scene with all four rivals left was nice as well.
The sauna scene with Kotetsu and Stephan was so.. hahaha Ash blushed? XD
Hopefully someone uploads the episode in a few days, I know some sites but you know people are not allowed to tell. :P
