I like to think that there is really no reason for demons to really seek out more information beyond their existence. I mean. They already have enough to worry about what with a demon threatening to eat their soul.
Also I really like that scene and I'm sure I didn't write it with the intent to be funny but afterwards I couldn't deny that it was entertaining.
Part of me wishes I had give the little boy an identity I thought about making him Syaoran but I gave him another part in the world despite the fact he might never appear. Oops
