If he spent it all. I counted about eight bundles of 100s, 100x100 = 10k per bundle.
No, those weren’t real expenses that he was listing, they were invented “expenses” to justify the bill that he was going to give to the Kettelmans. It seems he was serious about considering it a “retainer” and was typing up his bill to make the payment look legal.
I was watching the “story sync” on AMC with the episode last night, and they showed a list of all the expenses and it came out to 30k, so I think that is a pretty solid figure.
