[Sans leans back a little, not sure what to make of that comment. Okay, whatever. He decides to shrug it off and focus on the important part. He taps the tip of the stolen staff again his skull.]

Guess you missed this part, but I'm the Warden around here. You wanna fight someone, you come straight to me, okay?

[He winks. Then he points the staff at Lauren.]

Strike two, kid. One more and you're out of here. I'd hate to see you take your brother with you.

Now, better hope your pal here doesn't have a reason to give you a hard time.

[He points at Brook, and then vanishes from sight.]
