Always rumours about him, I doubt it's true. For the good of the world I hope he's alright because every North Korea leader has had to prove they are the worse than the one before and his sister as much as he looks like butter wouldn't melt, some of the stories about her make her much worse than her brother.
Very little is known about her though? I know that's kind of the point (NK) but all I've heard about her is her presence at the winter Olympics (when the joint-Korean team competed), a couple of empty threats, and her propaganda role to promote her brother's image. What do you know?
