>>53348882I think that's definitely possible, due to one very simple reason
Dawn cameo'd VERY late into JN, wouldn't it be a waste to not ask her Seiyuu to ask a few more lines for an extra appearence in MPM a few months later?
No need for any shipping conotation here. It's just plain and simple logic. I'm not even saying she'll interact with Ash directly, but It'd be a shame to not have her there, maybe interacting with Misty (first time), Gary and Brock
