[That answer? That answer is very definitely not a no. That's a yes in all but the most explicit terms, because Gepard is negotiating with him rather than rejecting him outright. All for the sake of learning his name! See, he knew that the good Captain could be fun, if he just had the right opportunity.]

I suppose I can agree to that! I won't ask you to abandon your duties to our fair city just for my little whims. But only for things that are a real threat! Your wounded pride doesn't count.

[There are other things that he could ask for that probably wouldn't be good for Gepard's reputation or for his pride, but also wouldn't be a direct threat to Belobog. It's still a very large leeway for him, plenty of room for him to play in.]

Of course not! That wouldn't be very fair, would it? [Sampo waggles a finger at him. Silly Captain.] You only get one shot at guessing, and if you mess it up, that's it! No name for you, and you owe me the favor. So make sure you do your homework and make it count!

[There you go, Captain-- fair's fair. Gepard can't just make endless guesses of every name in Belobog's registries until he gets a hit, and Sampo can't keep collecting favor after favor for every wrong guess.]

Satisfied? I'll play fair if you will.
