Toby followed the group, the small boy moving quickly and quietly so as not to be spotted. He didn't think the slaves would be too keen on him following along. After all, whatever they were doing, having a child along would probably make it harder. That is, it would seem like that to someone who didn't know Toby. The tiny child used to be a pickpocket in the streets before he got arrested and forced into work aboard the ships. He's survived a good year on his own. 
Toby was hoping the slaves would be able to lead him back to proper civilization, whether they wanted to or not. He doubted they wanted to stay in the jungle forever.
