*rubs marker off in a hurry*

Sorry, that was a heck of a party.

Anyway, I had to ask you something. I know you've just been reunited with your sister, but I would like to ask for a partnership. Latios, I challenge you to a battle. If my pokemon wins, I get to accept you as an addition to my team.

You don't have to accept. I understand if you don't want to leave your sister so soon.
