Kaede mutters very quietly to herself, "I haven't stolen anything."

Anyway, Kaede chews her bottom lip for a moment, clearly taken aback by all of this, then looks to Minato uncertainly. As far as she can tell, Szass is being honest with them, and it seems only right that they return the favor. If he were lying, he probably wouldn't have admitted to murder so quickly!

"Well... that's why we're here! There's a certain, um, magical artifact that we think might be behind it..." she ventures, looking to Minato again for confirmation.

Minato nods to agree with her. The murder thing is a little less than ideal, but there's useful information in there. "Who didn't you kill?"
