Totally cool how you can know that just from the previews, dude, I wanna be just like you. :O
Right. I thought the "ending" was actually very well done, Decade was really losing its appeal to me after some time and this brought it right back. I loved how quickly alliances changed and even Yuusuke questioning himself was done wonderfully, the entire cast was at the top of their game for these episodes, there was lots of emotion all around and the cliffhanger didn't feel WTFOUTOFTHECORNERYO as some previous series might have done.
