There's no way for Kurama to know that Trevor is just the distrusting type, but given time he will probably do so. For now, he's at least gathering he's forthright, which he rather likes; sometimes one just had to be.
"There should be somewhere nearby. I think I saw a few abandoned buildings.". He tilts his head in the opposite direction of the one Trevor came from to find him. "At the least, let's go in case any more bees are about."
And he means it, starting off in the direction he had just indicated. It's up to Trevor if he wants to follow along or not, though if he does not he'll find there's no questions asked. People will do as they will, after all.
