I don't really know if it's the great place to this but I take a risk...
Will Gary come back in Unova ?
I was surprised to see how Gary is missing me. I thought he could appear to take news from Ash's Unova League participation when he calls the Professor Oak, but I was disapointed to see how much some (not all!) people forget him. I know he starts to being a Pokémon Researcher more than a Pokémon Master, but I've noticed the fact that he appears 3 times (isn't right ?) in Sinnoh and it was fun to see him again. I thought, at start, he was going to study the new Pokémon of Unova, but now, I think my hopes were dispelled. Why not seeing Blastoise and Umbreon again ? (I don't really care about that ugly Electrivire...)
What do you think ?
