A few days ago, I realized something rather funny, XD.
I realized that two of my characters (Zeev and Sam) from one of my novels have a relationship that kinda-sorta resembles the one between Elliot and Oz in Pandora Hearts.
Zeev and Sam start off somewhat disliking each other, but work together anyway in a "I tolerate your existence, but I still don't like you." kind of way.
Then as the story progresses they eventually become close enough to be friends (and kinda develop a deep brotherly bond for reasons I'm not going to share here =D).
But during the significant chunk of time they spend in a mutual like-dislike relationship, they have many spontaneous arguments that flow a lot like the ones Elliot and Oz have. Particularly:
This That And this Though Zeev and Sam's relationship more of resembles the manga version of Elliot and Oz's, but the anime showed their arguments better, lol. Eventually they get to the point where they're more comfortable around each other, like it was between Elliot and Oz in chapter 47.
Yes, this is quite random and yes, using this avatar was totally intentional, XD.
