[The joke gets a small smile out of Mettaton. This is nice. Though his comment makes Mettaton realize that he actually... doesn't know much about Henry beyond his time here in Wonderland. Perhaps it's time to change that.]

Where did you grow up? It's a little sad to hear that the library was abandoned there.

[The hand on his shoulder is a welcome touch and Mettaton's eyes brim with tears again. The outpouring of kindness to his plight has been more than he expected, even if a part of his ego says that he should have.]

I wish I knew whatever it was I needed to do. I've lost so many people who were close to me here in Wonderland and yet every time it happens it feels fresh and new again. Like I'm re-learning how to grieve.
