I just finished watching the subbed version of episode 26, and I have a few questions about everyone's favourite subject: Time Travel.
Yuuto made a very strange remark, in my opinion, when he said that, "If he doesn't hurry up, we won't be in time for the Climax." I don't get why Yuuto has to rush to get Ryotaro back to the past for the Climax Scene. They can take as long as they want, so long as they travel back to the exact point in time for the Climax Scene. He didn't have to waste one card to transform and help Gun Form fight the Spider-Imagin, because he could have just waited for the fight to be over and just send Ryotaro back to the exact point in time for the Climax Scene, or the point in time where Yuuto left the other 2 Ryotaros and Ryuutaros behind. I hope you guys get what I'm saying, because it's really very confusing.
Also, I don't get why Yuuto didn't just transport Ryotaro back to the exact moment in time that he left, so that the others would not be worried over Ryotaro's disappearance. It would also help to keep his whole plan secret.
I guess this is an oversight on the writer's part, or maybe there's more to it in the movie, given how Ga-Ou screws time over. If anyone can shed light on this or expand on my theories, please do so, because I'm getting a big headache from Den-O.
