I'm very sorry for your loss.

[She really is. Tohru actually knows this feeling very well, and goes quiet for a moment.]

...I think I can understand that though. I catch myself thinking about it sometimes too. It's hard not to think about it now and then, since Wonderland is a place where the dead can come back to life, but...sometimes, I think about what it would be like if Mom came to Wonderland.

[It's such a strange, impossible thing to think about....but, it isn't really impossible anymore, is it? People who are dead in their worlds have come to Wonderland before, so why couldn't her mother?]

I wouldn't wish for her to be trapped here either. It isn't right, not when they should be at rest, but the thought that I could see her one more time...it's an incredible thing. I don't think anyone would really want to wish their loved ones to Wonderland, but I don't think it's about that. Not really.

[It can't be, because they don't have any control over who comes and goes.]

All it means is that you miss her. And it's okay to miss someone that much.
