I didn't think you could be so complicated but I guess I finally understand you better than I did before. It took a month but better late than never.

If you ever need anything I wouldn't mind giving you a hand. I may not be the most reliable person in this place but I could give it a try.

[Congratulations, Mouri thinks of you as a friend? That is good, it seems. So don't die, tinman, that would hurt]
