Hershel kind of just stared, unsure of what Heiji was doing. Was he reading his palm? Did Heiji like psychic stuff like that? He pondered this surprising new revelation about Heiji until Heiji spoke.

"A foil..." He glanced down at his hand for a moment, eyes widening as it all came together. "Oh! I think you're right, I think I might fence. When you were showing me kendo I had the strangest feeling about it, like it was natural but off."

He looked pretty darn pleased to learn something new about himself that just seemed to click perfectly into place. "Fencing, I wonder why I picked up something like that. Heiji, you're really something else, the way you figured that out. I knew we joke about you being a private eye but I'm really starting to wonder."
