That was a good question and Kate's nose wrinkled as she thought about it. It seemed like she had to think about everything or she'd just start blabbing shit she didn't want said. "I could ask you something I know the answer to. Who lives in the big bedroom, me or you? Try to lie."

Maybe it was a stupid question, but it was the easiest one she could think of. She had the biggest bedroom, of course and if he said as much, then she'd know he couldn't lie. But that didn't prove he had to tell the truth either.
