Spoilers, duh.
So at the end of movie, Po has Tai Lung in the Wushi Finger Hold. Tai Lung recognizes the hold, and panics, exclaiming that Shifu didn’t teach it to him and he was bluffing. Po says that he figured it out, and then with a Skidoosh!, he drops the pinky. It pans back, and we see a wash of golden light engulf the village.
So what happened to Tai Lung?
See, the way I figure it, the Wushi Finger Hold was like the Dragon Scroll and Secret Ingredient Soup. There was no secret ingredient, it was so fearsome because everyone believed it was so fearsome. The way Shifu plays it up when he’s using it on Po is a bit of a giveaway.
So what happens when Po finishes the hold? Is it really a powerful hold that does unspeakable things to the victim when used? Do unspeakable things happen because the victim thinks they will? Did Po wait for Tai Lung to cringe in fear when he moved his pinky and then snap his neck and bury him in a shallow grave back behind the noodle shop when he wasn’t looking?
Or am I missing a point somewhere?
