Istredd makes the exact same scrunched up face in response to that, like it also left a bad taste for him. "I'll give you this, it was very convincing. But those are the best lies, aren't they? Mixed with the truth." It's true that they didn't intend any casualties. The fisherman was doing them a service and paid the cost. The words are all correct. Istredd's never been good at lying so at least one of them is.

"The answer is technically yes." He is purposely being difficult right back at him because bickering is something they do well, and he could really use the distraction. Istredd knows it is illogical for him to be so nervous about this. He has all of his magic back. Lucifer is with him. Even if they get in trouble with bandits or criminals, the two of them are more than formidable enough for that situation.

So why does he feel like his heart is beating too fast? It is deeply frustrating and he's getting annoyed more at himself than anything else now. With anyone else, they'd have no idea how he feels, because Istredd appears as calm and composed as ever. "I suppose we should take a very good look at everything while we're there." Meaning, in case they ever have to flee there.
