I'm picking this arc won't last more than a few chapters (I hope not. I've not seen raws in advance). Amano-san broke a 'bone'. What's the bet its just a dinosaur bone and he's really just broken hearted? He doesn't seem to have been home in years but mum can travel back & forth every month? Not likely. Also, with a wife like that, why wouldn't he be coming home every month himself ? This is not shaping up as particularly well thought out...
