She stood up. "Look, Chase," she started to remove her blazer. A look of confusion came over her face as she did. She removed her blazer and hung it on the back of her chair and sat back down. "Look, Chase, I don't believe you. This has your fingerprints all over it."

"Tell me you believe me," said Chase.

"I believe you," said Ms. Slade before another look of confusion crossed her face.

"Holy shit!" thought Chase, "This actually works!"
