Oh, Iris... She in the game universe confuses me a lot. I mean, in the game she appears and acts like a child. No, like a real child. But in the anime, she appears to be somewhat more mature for that... Unless if I haven't done any extensive research (like I should). I don't know what the heck Iris would look like in PKMN BW2, let alone know if she didn't change at all from the first game.
That IS shame! I thought Hilbert / Hilda would appear somehow but I guess not. It would be nice to see them post-game indeed! I think it'd be great to see them like how we see Red in Pokemon Heartgold and Soulsilver.
