Okay, maybe the Snow King isn't so stupid. Even though his methods are not entirely logical. I think he knows Baby Girl is working with a hidden enemy, and is therefore keeping her close to uncover who it is. As for Baby Girl, a weakness can be exploited and your silly little affections are being exploited to your own detriment and I don't feel the least bit sad about it.
As for the Emperor, I don't know what to trust. I'm on the fence with him, and Ling should he cautiously optimistic about him, but not trust him until the Empress Dowanger and the Empress Consort are down for count.
