Importantly, Mole now sees exactly what Rat was doing: rather than rushing Mole or trying to influence him one way or the other, Rat wanted Mole to enjoy his old house so that he could make an informed decision about where he wants to live. Mole fully grasps the significance of Rat’s support, and perhaps in the future, Mole will be able to pay the favor forward to another friend. This experience also shows Mole just how much he’s changed. He’ll always be an underground animal at heart—but now that he’s experienced the beauty, happiness, and camaraderie of his riverside lifestyle with Rat, he knows that the river is where he truly belongs.
