I've sped watched through ep 6. I'll probably go back and rewatch more carefully once Viki subs are out. I really enjoyed ep 6, finally that wedding scene and FFB with XY that I had been waiting for for a year!
I also really liked the end of that episode, when Lirong Chang wonders why Jing is so calm when everyone is trying to find XY. Rather than also rushing to look for her, he is resigned to the fact that at least XY is saved from a loveless marriage. He tells his astral fox that this time he will let her decide who she wants to be with/what she wants to do. It's a change from the Dragon Bone prison scene in S1, when he is doing all he can to be with her and essentially exacts the 15 year promise from her at that time.
Was this part in the novel? I can't remember.
