Reddit user Master-Awesome explained: “The first heist, in which they robbed the royal mint of Spain, spanned over 22 episodes(13 + 9).
“In the second heist, they are robbing the Bank of Spain, this heist spans over parts 3 and 4 and is still continuing.
“Parts 3 and 4 combined are a total of 16 episodes. Sticking to the trend of 8 episodes each part since part 3, we can assume part 5 will also have 8 episodes.
“Adding that would make 24 episodes for the heist of the bank of Spain, which is more than enough to cover the whole heist.”
