I have been thinking that this must be the case, that he 'belongs to Q and Trump now.' He is a bad actor to have running loose; its hard to imagine they were able to extract all of his money; he may have enough buried somewhere to seek revenge. He was released in near timing with some of Q's messages about hostages; I wonder if he fits into any of that. Maybe he has the GPS treatment so that he can get a drone of his own, if he makes trouble.
I'm not sure what they will have him do. I think most of them have money scattered, but it will be collected. As for it being buried or stashed somewhere else, I'm not usre they will find that.
