Yeah, that certainly is part of it. I just felt that sometimes his care for Aang went a little beyond just you're-the-reincarnation-of-my-friend kind of love and into grandfatherly territory, especially when he went against the council to defend Aang. (And it would be a nice tie in the story.)

We should ask the creators if they ever intended Gyatso to be Aang's grandfather.
