You're studying late at Sunnydale High. The school is mostly abandoned as the sun begins to drop beyond the horizon. You're instinctively aware that staying out past dark in this city is dangerous, even though you're not quite sure why, but you goofed off too much in Social Studies and you need to cram out a paper for tomorrow's presentations or face the very real prospect of failing and being held back.

You approach the library, the hairs on the back of your neck beginning to stand up. The unmistakable feeling of someone watching you permeates you to your core, and you spin around, sure to see someone there. But there is no one, just the rapidly darkening halls as the last vestiges of day light fall out of the world.

Apprehensive, you gently push open the library door and step inside. It is as abandoned as the rest of the school. No, this is too creepy, even for you, and you turn to leave - but suddenly a distant bang stops you. You freeze in place, heart racing. You go to leave - and you hear the bang again. It's coming from the back of the library, behind the closed storage room door. Against all your instincts, you call out "Hello?" The banging quickens, as if begging you to come to it. Filled with fear, you approach the storage room door and open it...

Inside is sophomore Buffy Summers, bound and gagged and helpless, the short skirt of her leopard print dress riding up. Her eyes light up when she sees you, and she tries to say something through her gag as she writhes helplessly against her restraints.

What do you do?
