I love Avatar comics. It's like coming home.

In Katara and the Pirate's Silver Katara gets separated from the Gaang and has to find her way back to her friends. While, Aang, Sokka and Toph search for Katara, they stumble across a Fire Nation soldier who believes fake news:

that the Air Nomads were violent and had an army based on a poster

I think it is good that they address it and I liked that the comic did not really offer a solution how to deal with it except that you should talk to those who believe either straight-up lies or just believe different things than you do.

The story is set somewhere in Book Two: Earth of the series after the episode Bitter Work. I have some issues with how Katara was portrayed as "normally sweet and sensitive" and not tough at all. Because yes, Katara is sweet and sensitive but she has also always been tough. Maybe not in the same way as Toph but I also found it important that this series showed that you can be tough in different ways.

Also they argued that it took Katara longer to teach Aang waterbending than it took learning earthbending from Toph. But when Katara started teaching Aang, she wasn't a master herself yet. Meanwhile Toph was a master for years when she taught Aang. So I did not find that a good comparison.
