I know that's a very broad statement, but my character, Christopher, has the ability to tell if someone is telling the truth or not. He has a strong feeling of resentment to people that lie excessively (or for the wrong reasons), so someone that has something to hide and lies to protect the secret would bother him greatly. I'd rather it not be something trivial, such as "I stole a pack of gum from the convenience store down the street," but we can work out the details through PM.
