Aragorn, Gimli, and Legolas enter Fangorn and follow the trail of the orc and hobbits.
The ents begin speaking to one another. Apparently Gimli upset them by raising his axe.
Legolas senses Saruman's approach and they prepare to fight him before he's able to speak.
But it's no use. He deflects their attacks and disarms them immediately.
But wait a minute. It's not Saruman at all; it's Gandalf.
Gandalf recounts the story of how he defeated the Balrog and then spent many lifetimes away from Middle-earth before awakening as a white wizard. We take it he's more powerful now.
He tells them not to worry about Merry and Pippin, who have a role to play in the awakening of the ents.
He calls his horse, the majestic Shadowfax, and they ride toward Rohan.
