[He may not know Lucy very well at this point, but just the feeling he gets from the way she talks and carries herself, he has a feeling that smiles like that must be pretty rare. After all -- they met at a dick festival and not once did he see her laugh at all the nonsense going on!]

[It causes his own smile to brighten further -- and for good measure, the ends of his hair even tint to the same pink shade as Lucy's thanks to the Kizuna slowly building between them.]

Then all the more reason I'm glad that I did! Being able to find a new place to call home, after losing the place you once knew... there's something really special about it. And it's not always very easy, either. So I hope you're able to keep enjoying the life you have here.

[It's something he knows all too well from experience. Traveling from world to world, until the only place he felt at home was by his sister's side -- and then losing even that. If staying in this world could be an option for those with no home to return to, then he'd happily fight for that right for them.]
