In season 7 Cersei attacks
House Tyrell and gets all their gold,
in order to pay the debts to the Iron Bank and then ask their help to hire some mercenaries. But before the gold is back in King's Landing
they're attacked by the Dothraki and a dragon, and (apparently) lose the gold.
It made me think that the support from the Iron Bank was lost too. But, in the last episode, it appears they still have the support of the Bank to hire the mercenaries.
So the question:
Did she recover the gold after the defeat or does the Iron Bank help her without having recovered the gold?
