Sarah and Walter Swap Minds

Walter moved forward again and tapped Sarah's shoulder ... and suddenly his perspective had changed. He wasn't looking at Sarah anymore. Instead, he was looking at ... himself? What was happening? Sarah blinked and looked horrified. She didn't know what happened, but it seemed that she was no longer in her body. Instead, she was in that dweeb Walter's body. She looked down at herself (or himself) in shock and disgust. Then she looked back up at her original body, whose face looked as shocked as hers. "What did you do?" she demanded, hearing Walter's voice instead of her own.
