Hmm.... so Melchior loves stories about the gods and in the past the high bishop was chosen from among the archduke's children...

I think Melchior will succeed Rozemyne's post as the High Bishop once she vacates the position to marry.

Seeing Rozemyne's interaction with Wilfried following the tea party with Melchior was fun. They already act like a married couple there, being very reminiscent of some interactions Sylvester and Florencia had. ^^ That sure was cute.

So Ferdinand is taking his training seriously. I think this has nothing at all to do with a simple "change of pace" and all with his fight against Hassheit. He's probably shook about how hard a time he had defeating his old rival and/or feels like he's rusted.
