Corrected entry: After the Furious Five go after Tai-Lung, the next morning shows Shifu very calm, not at all concerned about where his pupils are. Since the Dragon Warrior prophecy is a major plot point (it is stated repeatedly that ONLY the Dragon Warrior can defeat Tai-Lung), Shifu would know the Five would have no chance against him.

Correction: Shifu doesn't seem concerned because he doesn't know yet where they've gone.
