N appears to be on the Pokémon League battlefield.
Edit: Someone on Serebii pointed out that it looks different to the battlefield. Oh well. Could be anywhere really.
Looks like Ash's Pikachu will probably be the "trigger" for N's eventual change of mind in the anime, much like in the first encounter with him in Accumula Town in the games.
Where he see's that he's wrong or something else?
Precisely. I'm positive that he's going to read Pikachu's feelings and notice how much he loves Ash, which he won't comment about at the time but will mention it at the end of the saga. In BW and these games, N talks about how Hilda/Hilbert's Pokemon said they liked them when he talked to them the first time, which surprised him.
I just watched someone's video thoughts on this new arc, and I have the same questions as him, such as: will this be BW1 version of N(antagonist) or BW2 version(protagonist). Of course, if it's the former(hopefully) we know how the plot's gonna go. If it's the latter, then the story will be about N helping Ash and co. defeat Neo Plasma, while we get flashbacks of the events in BW1.
Another concern he has is if the anime writers will use N to his full character potential here or dumb him down?
