Henry watched her reaction to the whole parent thing, it was sad enough to cause his own sad expression. Everything she said only made him feel sad for the girl, who were 'they' that she kept talking about, and were they good or bad. Henry wasn't sure what to do, so he gave her a quick hug before letting her go. "My bad, I got your question mixed up with something else, the parent I was thinking of is different. You do have a parent, I would guess it to be Densen. The parent you are thinking of is someone you knew for a long time, that cares for you." What Henry said, was obviously just him trying to make her think he got questions mixed, so she wouldn't be sad. So he had to hope that this little lie would work. It's not that he wanted to lie, he just didn't want her to be sad.
