Episode 25:
Lam Ping Tze truly is emerging as a tragic hero of this story. Don't focus too much on the term "hero"; focus on the "tragic." He truly fits the definition of "tragic" in the classical, literary sense.
What is a classical tragical hero? In literature, this archetype begins as a noble, respectable, basically decent person, but due to some deep flaw in his personality, makes a fatal decision (or a series of them) that leads to his downfall, which usually also implicates those who matter to him.
Lam Ping Tze checks all those boxes. His desire for revenge drove him to learn the Pik Che Sword Technique, which drove him mad. Alas, it cost him everything, but he doesn't seem to realize it.
I can't fathom Ngok Ling San's continuing devotion to him. It's even worse than Muk Lim Chi's misplaced devotion to Yeung Hong in LOCH. Looks like she's going to buy it very soon.
I had a feeling Tzor Lang Sim wasn't done, and he isn't. Looks like he and Ngok But Kwun are on a collision course, and out there waiting in the wings is Yam Ngor Hang.
