Sandra and her sister, Melanie

"What do you think it is?" Melanie asks her twin sister, peering at the vial in Sandra's palm.

"I don't know..." Sandra says. She can't take her eyes off of the red fluid.

Melanie and Sandra found the box in their (recently deceased) great-grandfather's house. A notorious hoarder and all-around kook, they were surprised to find the rare looking box buried with all his other junk. The sisters had been storing the stuff from his house in their attic, as they sorted through it on weekends.

"Can I hold it?" Melanie asks, but Sandra, in a daze, is unresponsive. "...Sandra? Hello??"

Sandra and Melanie

Sandra turns from her sister, and unscrews the lid to the vial. A cloying, coppery smell fills the air. Sandra closes her eyes and inhales deeply. She is compelled to sip from the vial. Sandra brings the vial to her lips as Melanie blathers on. Melanie moves to stand in front of Sandra, and tries to stop Sandra from drinking the liquid.

"Sandra? Sandra? What are you doing?" Melanie screams, as Sandra begins to drink the red fluid. Sandra takes one sip, and the enchantment is broken. She shakes her head, resealing the vial.

"I...I don't know why I did that..." Sandra says, confused. Melanie gives her a concerned look, taking the vial from her sister. Sandra suddenly feels very dizzy, followed by a pain in her stomach. She doubles over, falling to her knees. Sandra suddenly looks very pale, the color draining from her face.

Melanie gets on her knees in front of Sandra, her hand on Sandra's shoulder. Melanie gasps, eyes wide in horror, as a pair of razor sharp fangs sprout in her sister's mouth.

Sandra looks up at her sister, a flash of red in her eyes, and smiles.
