If Roxie wasn't phased by Gellert Grindewald, there was no way she'd see through Cassius. Roxie simply believed for too deeply into good intentions. There was evil in this world, but everyone was good at heart. There was a way to save everyone, after all. If Tom Riddle had someone to love him, he'd have been nicer and wouldn't have gone on killing sprees. Everyone said Gellert was a bad wizard, but Roxie believed there was a way to save him. Maybe that's why she'd been brought here. It would be difficult though, since she'd promised two people she wouldn't speak with him.
Roxie grinned at the sight of the dog-toy. "That's fantastic!" she said, hardly able to contain her excitement. Being outside would be much nicer than in here, after all. Without waiting for confirmation, Roxie was already outside and was jogging a little bit off from the entrance. "Far enough?" she called and raised her hands into the air. Ah, childlike fun. There was something so simply joyous in tossing a ball around.
