Hmm. I'm still a little bit wary even though that sounds better, but, um... if it is going to be that, it has to be something that isn't going to be immediately used all the time and I'm still leaning more towards lie detection.

Okay, that's fine actually. It kind of reminds me of, if you're familiar with Fate/stay night, the Instinct skill, which more or less operates very similarly.
