What do Ты think Duncan did with the money he earned?

Get him self out of Juvie!

I dont think he did anything with it. Didnt he lose it to courtneys lawyers или in the desert. if he did use it then why was he in TDWT

That is the biggest mystery of TDA and TDWT. He either got himself out of juvie или didn't spend the money yet. I really don't know.
