Her demonstration

The pool is behind a fraternity house and while it's not very late, the property seems quiet tonight. Even college kids can't party every night. Pammy and you had walked around back to get to the pool, where you see safety tape has been used to cordon the area off from the house it's attached to, likely because of the incident with James Danker. The water is still and clear.

"This is where it happened?" you ask.

"Yes."

"Okay. Show me what you did. Do it slowly," you instruct Pammy, paying close attention as she proceeds to make some hand motion with her fingers followed by some sort of incantation in a language you don't recognize. It doesn't matter, as you try to remember the sounds coming out of her mouth. When she finishes the incantation, she bends down to touch the water in the swimming pool. At first, you think the spell failed, until you realize that the water is starting to freeze from the edge of the pool and the ice is slowly spreading. You and Pammy watch in silence, and it takes about 2 minutes for the entire pool to freeze over. Standing by the side of the pool, you bend down and touch the ice, giving it a knock to see how solid it is. You thought maybe the spell would just freeze the surface of the pool, but it looks like the entire mass of water is frozen. It's no wonder James Danker was hurt so badly when he fell.

As you stand back up, you hear an unfamiliar voice from behind you and Pammy.

"Well, I've seen enough," the voice says.
