Treebeard muses, "I must do something, I suppose." Saruman used to walk in Fangorn forest and talk to him, but on reflection he says that although he told Saruman many things, Saruman never told him anything. He realizes now that Saruman is plotting to be "a Power" and wonders what evil he is really doing: why has Saruman taken up with Orcs, why there are so many Orcs in his woods, why these Orcs are able to bear sunlight, and he is angered by trees being felled "to feed the fires of Orthanc." He overcomes his anger and then, thinking aloud, begins to make plans for the next day. He also tells Merry and Pippin about the Entwives. The critic Tom Shippey writes that Fangorn's explanations are "authoritative and indeed .. 'professorial'. They admit no denial."
