[@McFazzer]Honestly, I kinda expected someone to eventually ask this.

Well, you don't really need to be a criminal. That's just an option; just someone who needed help but couldn't get any due to the circumstances they were in. Choices would probably range from loner, problem child, outsider to something more drastic as an actual criminal; nothing too intense or dark though. You could be a totally normal kid who just likes the idea of what Tumble is doing and wanted to join in.
