Envy saw that Tulio left his pokemon at the center, but for some reason he didn't really feel comfortable with just leaving Chimera with strangers. Maybe they were trustworthy, maybe not, but he didn't feel like chancing it right when he was starting to like the little guy. He'd feel much better later, when he'd be able to stay there and make sure.

Then Tulio ran up to some blonde guy, and Envy looked on curiously. Who the hell was that? Someone Tulio know? He decided to hang back for a moment and see where this went.
