Shifu says: “The secret is not in the scroll. It is in you. And now… in Po, too.”
Po looks at his own paw, grins, and says, “So… can I be in the next scroll?”
Shifu learns that Boar is heading to the to sell the scroll to an outlaw syndicate. Shifu cannot go himself (he is guarding the palace), so he sends each of the five young warriors individually, believing any one of them can stop Boar.
Tigress answers for all: “A master alone is strong. Five masters together are unbreakable.” Back in the present, Po asks Shifu, “So the scroll tells how the Furious Five got together?”
