Jimmy left some cash for Roland to ensure his daily life wouldn't be a problem. As for the source of the cash, there's no need to worry about it. No one could trace anything from the cash anyway, maybe just some slight powder residues or the like, but Roland's daily expenses would definitely not be an issue.
However, the items Roland wanted to take to the Dark Tower World needed careful consideration, especially since the energy for the portal to the Dark Tower World remained a big problem. Fuel was scarce and hard to gather from other places, so he couldn't travel back and forth too many times and needed to prepare everything thoroughly.
Jimmy, on the other hand, didn't think too much about it. With Nia's due date approaching, he was even more nervous than she was. If it weren't for work-related matters at the bureau, he certainly would have stayed at home to keep Nia company.
