Buffy.
Do you think that this newcomer would have thought to look for that specific hotel among the dozens of others listed in there if you hadn't have mentioned it to her?
Do you even know if she's capable of something to be protected against? Do you know if she's stronger than everyone there combined? Do you know if you're gearing up to attack a mentally ill woman who could be easily hospitalized?
Obviously you can't handle it if you can't even properly think ahead. I'm calling in the big guys for this one, Slayer, you stay out of it.
