Gandalf: Well, why does it matter? He's back!
It matters. I want to know - why did you come back?
Look, I know you doubt me, I know you always have. And you're right... I
often think of Bag End. I miss my books, and my armchair, and my
garden. See, that's where I belong, that's home. That's why I came
back... 'cause you don't have one, a home. It was taken from you. But I
will help you take it back if I can.
