Gwen is a vampire, seek the safety of the cross

You quickly walk toward Tina, getting behind the cross. From there you can see the creature Gwen has become. She is thinner, her legs are even more shapely, and upon closer inspection her breasts have grown a cup size or two. Her eyes glow a devilish red, her teeth have elongated into fangs, and her lips are the red of blood.

Tina yells. "Back off Gwen, he doesn't want you."

"You should have just listened to the master, Tina. You have no idea how great this feels. And, Jack, you may think you've escaped me, but I'll be waiting for you to change you mind."

With that she disappears into a cloud of mist.

"Tina, what happened in there."

"I was looking at the art in the room, when the coffin opened up. Gwen was near it. He simply stared at her and beckoned her to come to him. She went to him. He wrapped her up in his cape. I...I...thought it was just part of the show. Then he opened his cape and they stared at me with glowing red eyes. I started to go to him, but then I remembered the cross. I ran out looking for you."

"I think to stop this we have to destroy the array."

"I think I saw it, but I'm not sure how you would destroy it."

"What do you mean?"

"It looks like it has been built into the foundation floor. Come on I'll show you."
