Okay, not a good tone, he can tell that much. Probably a Frisk that isn't on good terms on him... but this didn't tell him anything about whether or not Frisk has that knife and intends to use it. They've got the rundown already, right...? Right. He doesn't have to explain that you can't kill or be killed (if you don't want to or are extremely lucky) in the carnival.

How to approach this delicately...
