[He listens carefully, and this time he puts a hand on Sokka's shoulder.]

I know. It's hard for me to look past that, too, what he'll do. [And he'd still have his people.] But I know it must be hard for him. After all, it's... it's not like he has people like Ikki or Tenzin, to give him hope for his family's future. When I think of the last time I saw Roku back home, I can't tell if I'm more mad at him or sad for him. Because... because of how lonely he must have made himself. I don't think he ever got over how much he feels he let the world down, so he thinks the world in general is so much more important than attachments. Maybe that's why... he never asked about Zuko. Even when Zuko was traveling with us and being friends with us, Roku never asked to see him.

But now that I'm back here again, I know even more why I don't want to be like him. [He brings his hand back and looks down.] When the time comes for me... I know I'd want to see my family. I'd find a way with Korra. I don't want to change like he did. I wouldn't - don't want to be alone.
