[...Mettaton's smile is a little more genuine this time. Really, he has worse things to worry about than some socially inept kid.

Again. Kaworu is not fully forgiven. But MTT is willing to give him a bit of slack and see what he does with it.]

I'll be sure to bear that in mind for later. There's no point in trying to be humorous if no one knows what the joke is!!

At any rate, I would love to believe that you were only looking for me in these halls, but is that really it? Or were you wandering out of boredom?

[Maybe Kaworu has night vision to make this easier, for all Mettaton knows about him.]
