"What is experiment 304?" George asks.

"A silly vampire thingy. Not important but he is gone now." Annie says. She looks around the room. Sees nothing and leaves. When the door closes Robbie appears again.

"Hey.." George says confused. He doesn't really understand how Robbie appears and disappears.

"I can make myself invisible. Don't tell Annie." Robbie says.

"She called you experiment 304.. do you want to explain it?" George asks carefully.

It really hurts. I got blind for months. And you half-vampire guy. Have to be careful." Robbie whispers
