[Wow. Sans isn't exactly a soft hearted person, when it comes down to it, but he finds himself a little bit worried. For all he knows, this girl is just going to head on back home when she's done here today, but there's always the chance that she'll end up in the proverbial net.

There's a limit to how much he can or will do about it, of course, but he can offer this much.]

Huh. Sounds like a big job. Well, since you're the one watching out for him... be careful about who you hang out with here, today. This carnival's not too bad, but sometimes people will try to get you to promise more than you can follow through with.

So, uh... keep an eye out, alright? [He taps the side of his skull.] For the little guy.
