Hazel probably would have just stood there waiting for the others to take care of things. If she hadn't noticed that Loki was gone.

She looked around to make sure she wasn't mistaken. Behind? Up? Nope, can't see him anywhere. Cloud seems to have an idea where to look and starts further into the woods when he realizes she wants to look for the boy.

She'll just follow her pokémon into the woods. She's not really paying attention to the fact that her current path would lead her around the Virizion. As long as it doesn't notice and decide not to let her anyway.

Has anyone even noticed that she's started wandering off?
