You guys are saying that Master Yue and Yun Que were lovers, but... what if she was actually his daughter? The different hair colour on Yue and the "kid" Xue Tong Zi suggest that they practiced some kind of martial art that makes them look much younger than they really are. What if Yun Que actually infiltrated Wufeng as a spy, became sworn sisters with YWS, but her cover was blown and she was killed? And then WF lied to YWS that she was killed by Gong so that she would go seek revenge on them?
Yue using the claw move on YWS could be a test to see if she knew how to counter it. If she did, that means she was trained in WF and therefore a spy. That's also the reason why she keeps falling for the same move over and over again. She can't get out of it because if she did, her identity would be exposed.
Oh that top half is complicated especially given the way his flashbacks were of her and how he caressed the bracelet also given the fact that he’s not looking 50. If he was her father, that would just be creepy.
Now the other half I’m more inclined to agree with but at the same time they give themselves away for better or worse to her. Because who else would know that move and why?
