When Hawkins is getting into Giacomo's clothes, Gene does not tell him who their man inside the castle is.
Hawkins: After months of waiting for this kind of action, what makes you think that anything, anything would get me to betray my confederates?
Gene (without missing a beat): Because they'd put you on the rack, break your every bone, scald you with hot oil, and remove the nails from your fingers with flaming hot pincers.
Hawkins: ... I'd like to withdraw the question.
