"no. should they be?" His tone remains a little more sharp than it usually is. In Sans' experience, people who are this jumpy about someone coming for them usually have some good reason for it.

...still, whatever that reason is, it probably doesn't concern him right at this second. Kuja is not who he wants to fight with. Sans waves both hands - one remaining wrapped around the knife - and the blasters spin out of existence. For now.

"just some pets of mine." A lie - his blasters are mindless, though he remembers that that isn't the case for all of his incarnation. "nothing for you to worry about - their bark's worse than their bite. but i just kinda came back from the dead again, y'know? seems like a guy's gotta work a little harder to protect himself, these days."
