Buffy isn't entirely sure they won't attract anything else either, but she's not going to shush her sister, at least not right now. So far, they seem safe enough and she'll let her have that. She keeps watch though, scythe at hand just in case. There's always a just in case with Dawn.

The just in case comes a few minutes later, a creak and a crash.

"Dawn." Buffy says it in warning, listening and looking for anything else. "Come here." She holds her hand out to take Dawn's and draw her close to her.
