For a moment, Luka is distracted trying to figure out the hand situation. It wasn't typically how people took his arm, but he figured maybe Six was just inexperienced with this sort of thing. He hasn't come to the realization yet that Six might have more than two arms, despite him having referenced it that morning.

Luka's still feeling quite pleased with himself as the monster leads him to the exit, but then Six asks a question he hadn't expected.

"Oh, it's been awhile since anyone's asked me that." Most people who were aware of who Luka was knew the story by now. It was something that was simply unavoidable. Everyone wanted to know how and why. "When I was young I witnessed a magic-related explosion that burned my eyes. That's why I can't see."

That was the abridged version. Luka figures that a monster wouldn't be terribly interested in all the finer details of the incident.
