Helena thought for a moment about what to ask Mystery.  She didn't want to go into his background since that seemed like a touchy subject.   "What about your favorite color? Yours too, Ed.  We answered some questions earlier and that was one of them," she said, trying her best to strike up conversation.  Even though it was a simple question, the answer and the way they answered could tell a lot about them.  When Valencia gave her the smile, Helena nodded and returned it.  She understood, sometimes Helena liked to be alone even though there was company.
