Crime: ZZR poisons the eyeballs off everyone, steals HSDS, and kills Zhu'er because she wakes up enough to be witness. Zhu'er is further scarred on the face because ZZR thinks it a nice touch to blame ZM for everything. ZZR also ships ZM off the island to set up the situation to align with her intentions.
Resolution:
Part A
Ming happens to capture ZM and bring her to their headquarters.
ZZR + ZM = Mega cat fight
Zhu'er is discovered alive and unscarred (what?), yet she has become slightly insane and suffers selective memory loss. ZZR is edgy of being found out, ZM is edgy among enemies and spitting mad at ZZR, the whole Ming are edgy, ZWJ is just plain confused.
YX and FY re-create the scene of the crime at night, and bring Zhu'er to observe. The re-enactment triggers Zhu'er's memory and she shouts:
"ZZR you are so despicable, ZM run!"
YX and FY both agree that this more a less confirms that ZZR is the culprit. YX feels it would be wrong for ZWJ and ZM to be together, because they are national enemies, and it wouldn't be good for the troops to know their leader marries the enemy. It is also quite clear from YX's typically jealous nature that he also hates ZM because she doesn't defer to him and is very well more intelligent than him, and of course, if ZWJ ever married her, she would be of more influence than him, as YX is well aware that the dummy ZWJ is in love with her. ZZR maybe evil, but I guess YX thinks he can control her better. I personally found YX to be quite manipulative in HSDS94.
YX convinces FY to lure ZM into a trap, where she is convinced that if she holds a dagger to threaten Zhu'er's life, it would trigger her to remember her memories. ZM of course suspects, but she absolutely trusts her previous master (I feel sad for ZM, that the first man she truly is willing to trust and make herself vulnerable too, betrays her the very worst way). The inevitable happens, they drag in the inept ZWJ to observe ZM trying to 'kill' Zhu'er. ZM is willing to die, FY has a last moment of remorse and tries to beg for ZM's life, ZWJ thankfully doesn't kill her. FY explains to ZM that he had no choice, because ZM is Mongolian and the enemy. What a wuss!
Part B
ZWJ bumps into ZZR right before the attempt to rescue XX. ZZR wants to rip his guts out because he jilted her at the altar. ZWJ is willing because he is remorseful, YX thinks that's bad so decides to blurt out the truth about ZZR, so ZWJ doesn't brainlessly throw his life away for the culprit. ZWJ gets all hurty and disappointly because he realises he tried to protect a "lying snake".
After healing himself, ZWJ for once gets all manly agro at YX for keeping the truth from him. YX indignantly tries to object that he was "doing it for the good of Ming". I like ZWJ's come back: "If you are going to keep things from me, and not respect me as the leader, I might as well step down from the Ming leadership". So, YX being understandably afraid of losing his puppet leader, gets all apologetic and suitably subserviant.
ZWJ finds his godfather, the first things his godfather asks if where ZM is. That she is innocent, that ZZR is the culprit, and that he instructed ZM to go and prevent the wedding with a lock of his hair as proof of his word.
Side note: before ZWJ and ZZR's near wedding, ZM had found XX. XX had willingly allowed XX to kill her if he truly believed she was the culprit. Her complete lack of self protection and probably other cues XX picked up in his sightless wisdom, convinced XX that ZM was innocent.
And so, ZWJ gets all twisty inside that he has wronged the woman he loves, because he more or less confesses this to ZM straight after these events. She twists all the hurtful words back on him (I can almost recite them verbatim, but I won't, can't be too nerdy), in her rejection of him (he was horrifically hurtful earlier on, even allowing her to be nearly raped by soldiers because he didn't want anything to do with her...any man to stand by and do nothing in that kind of situation , whether or not it's the woman you love, is plain despicable).
