Tansy works at the prize counter. She comes off as creepy just because she talks about weird things. She has dyed blue hair, and blue eyes. She wears glasses. She’s sarcastic, and a very good liar. Most of the kids who frequent the pizzeria think she's an alien. She pays the kids real money for their tickets because she’s saving up for the stuffed pig worth 10,000 tickets at the prize counter.
Tansy had invited you to her house after work that afternoon. She felt as though you were a neutral force in all of this chaos. After all two employees from Pietro's Pizza Palace were now dead. First Lilah, now Trey. It would be wrong to say that the mood wasn't sour. Tansy of course, wouldn't show publicly how its been affecting her.
But as the resident conspiracy theorist of course she had an idea of who she thought the killer was. She almost didn't want to admit it, but it seemed right. As soon as the two of you were behind the closed door of her room she blurts it out. "I think Martin is the killer!"
