In the newest episode of BW Adventures in Unova, Ash says that he's never met Reshiram before and the only time he's met Zekrom was in the very first episode of Black & White when Pikachu and him first arrived in Unova. But what about the Pokemon Black and White movies? He meets Zekrom and Reshiram in those. At first I thought maybe the movies haven't happened yet or something, but then I remembered that Ash's Pignite was still a Tepig in those movies, so they had to have already happened. But why doesn't Ash remember them? Did he somehow get his memory erased or something? Or are they just separate from the series? All the other Pokemon movies coincide with the series because they make references to them throughout the series.
Can somebody please help me out here? xD
