The Return of the King
"Young Master Gandalf. I'm glad you've come. Wood and water, stock and stone I can master, but there's a wizard to manage here, locked in his tower."
"The filth of Saruman is washing away. Trees will come back to live here. Young trees, wild trees."
"Bless my bark!"
The Two Towers
"Little Orcs, burarum."
"Tree? I am no tree. I am an Ent."
"Treebeard some call me."
"Side? I am nobody's side, because nobody's on my side. Nobody cares for the woods anymore."
"Hobbits? Hhmm, never heard of a hobbit before. Sounds like Orc mischief to me. They come with fire, they come with axes! Gnawing, biting, breaking, hacking, burning! Destroyers and usurpers, curse them!"
"Maybe you are, and maybe you are not. The white wizard will know."
"My home lies deep in the forest, near the roots of the mountain."
"I told Gandalf I would keep you safe, and safe is where I'll keep you."
"The trees have grown wild and dangerous. Anger festers in their hearts. They will harm you if they can."
"There are too few of us now, too few of us Ents left to manage them."
