Damn. Giles spots the vampires about the same time Sunshine does. He feels a moment's surprise at her calm response to their arrival - considering her state when she arrived in the sitting room, he wouldn't have expected such a small reaction to seeing vampires again. However, he's quickly distracted by their uninvited guests.

"Vampires." His tone is far from afraid - more toward the weary and exasperated end of the spectrum than anything - but he is concerned. A half dozen is too many for him to fight alone, and being in the middle of the room as they are, he can't protect Sunshine and fight at the same time. He mentally berates himself for not at least arming her with a stake of her own before they left the sitting room.
