Halloween Horror Nights Comes True

You and Cassandra walk into the amphitheater to watch the Magic Show. You are hoping the the guys will no longer be following you when the show is over. Both you and her find a sit in one of the middle rows. It is not to close to the stage, but not to far. You look around to make sure the guys are not here. You don't see them so you figure you must have lost them. The amphitheater is full. All the lights go off all of a sudden. Then, boom, a big flash of light lights up the stage. Shortly after, smoke fills the stage and a magician rises from it. You can hear muffled cheers. After a series of stunts he points to the crowd. For some reason, everyone looks at Cassandra.
"He wants me to go up there, on the stage," Cassandra signs to you.
"Go! It will be fun!" you respond.
She stands up and goes. The magician says something and the whole crowd cheers. He then flicks is finger and two women walk out from behind the stage with a box and a saw. "Oh my god," you think, "He is going to do the cutting in half trick!" You can tell Cassandra is nervous because her eyes go wide. The magician then opens the box and Cassandra hesitantly steps in. She lays down and her head is out of the box through the hole. The magician closes the box and takes his saw out. Finally, he starts cutting. At first Cassandra is smiling, however, in a matter of seconds she starts yelling. Although you can't hear her you can tell by the movement of her mouth. Her eyes close and her head falls back. "Oh my god," you think. When the magician opens the box blood spills out along with flesh, organs and tissue. You feel like you might throw up. All of a sudden the lights go off. Someone bumps into you. You can barely see but you can see enough to know what is going on. Everyone is running. You look around and see one of the guys that was following you again. He starts walking towards you and you run. Where should you run?
