I don't know what just happened. After the movie, they're all friends again, but in the episode where the eds turn old, it looks like they have normal lives again.
All the days when they had fights, Double D never did anything. And in the movie... well he did it. I also think it's cool how it showed the first episode of the series showing Double D labeling his room, and at the end of the series, labeling "The End"!
There was also an alternate ending in which Eddy's brother gets arrested. 0_o Maybe they will show it in a future DVD release or something. Kevin only cared about his bike in the movie. XD
