I don't know. He flew away on Reshiram, and I've been looking for him. [Sort of.] He said that he didn't understand Pokémon as well as he thought he did which was true so I'm guessing he took off to try and get a better understanding of them.

...I'm a little worried because he really doesn't understand anything and it's like letting a toddler run off all by himself, but I'm sure Reshiram is keeping an eye on him, at least. I just hope he's not getting himself in more trouble, he's a naive guy. Like I said, he's just like a Pokémon. Like a newly hatched Pokémon!
