Hmmmm I wonder if anyone could heal it. Like water and healing abilities tend to go together in fiction.

Lol maybe? I'm not sure if that's too out of the scope or not. I mean even in Avatar only special healing water blessed by spirits would have healed Zuko's eye, and as we saw when Katara eventually used it on Aang, it didn't heal [i]his[/i] scars at all.
