At the interaction with the barkeep at the Pelt of the North, when he asks you to cover for him for the deal with Foggy, what part of his explanation is a lie?
Hi! I'm sorry if it's not stated clearly, I'll write a note for myself to look into it. The intended lie is that he still considers paying her for joining forces - the truth is he's just playing for time, hoping to bail before he faces any consequences for manipulating her.
