he's a total legend though

Headcanon that during their visit to the old West, Leonard Snart took the opportunity - after a bit of research - to visit the local bank, a small branch of a much larger bank - and got himself an account with a very nice interest rate and deposited the money he’d gotten in exchange for a number of lovely, sparkly nothings he’d picked up here and there…

(I’m not saying that Len returns to 2016 Central City a far richer man than many of his previous targets, but he totally does. Doesn’t stop him thieving, though).
