I mean, just think about what he was like waiting while Shen Wei was in Dixing. And this time, the situation back home is bad and he can do NOTHING about it ...

Oh, that's true. At least some of his tension while SW was in Dixing was the inactivity. He needed to be doing. And luckily YOHE gives him plenty of things to do and problems to solve. But yeah, you're right. And he just saw WZ & SZ die in front of him -- how could he not be worried and distressed for his team and his city, if not for himself?
