Yes, he will probably try to talk Koichi out of leaving.
you think? i don t have him for the talking type.. maybe he ll kidnap him or smth till the time passes and he won t be able to return?
I mean he's not a bad guy. If he thinks about everything, he'll have to plan it through to where it won't effect him in a big way or bad way and keep it to where Koichi will stay. He'll most likely consider kidnapping him again. But they're at the palace now so security is great or greater. Plus Klaus knows magic. The most likely best outcome would be trying to talk him out of it or something similar. He might kidnap him to chat. But that's just my speculation.
He's planning something I can sense it (￣∇￣")
