Jon's wishing stone could have given CTS to anyone in town, but chose to give it to Thea Woods (a butch lesbian who went to school with Jon and Karyn). Anyone who made physical contact with Thea would begin to transform into the type of person she was. They would mimic her personality, general physical traits, sexual orientation, and even choice in clothing.
At the exact moment the stone gave her CTS, Thea was riding down the street on her motorcycle, all decked out in her usual attire: a black tank-top (with no bra) and a leather jacket, a somewhat baggy and ripped pair of jeans, and a pair of combat boots. Around her head, she wore a black bandanna.
She stopped at a red light, revving her motorcycle to show off her "masculinity", despite still obviously being a girl, then began to head towards her hot girlfriend Krista's house. But she stopped suddenly when some moron tried to cross the street in front of her. She shoved the person out of the way, not realizing that she had just infected that person with the CTS virus, which would turn that particular person into a butch lesbian very similar to her.
Thea sped down the street, the person she shoved completely forgotten. But who was the person and what other people would be infected?
