Was she aware of these things before coming here? That question made Faith laugh and smirk in his direction. "Hey I met my first vampire when I was fourteen. This shit is way old hat for me. And it's not just here. Shit is everywhere but some places it's just a lot more obvious than others."
She didn't want to get into hellmouths and what they were and that things were attracted to them. Leaving it as some places were uglier than others was good enough for now.
