Gotta love Tahno.
I don't really understand how he became so popular seeing how he's such an incidental character, it's like the fandom are all me or something! He's from the Legend of Korra
A lot of people want him to join the main cast, and I think that would be hilarious, but then I also ship Lin with Bumi, a man with one line (a crazy shout on top of an airplane) so I don't think I'm exactly on solid mental ground here...
But look, if the hobo came back, anything's possible!
