Lin and Bolin...drinking probably yes. Haha, never mentioned again. Ikki was stepping up, I was happy about that. Tenzin, Lin...please become relevant again! You're not cool with Toph in the swamp? I think it suits her. Though Zuko should have at least enlisted Toph and Katara to do healing and provide backup, you're right there. Though Toph was found in a swamp, in Aang's vision so I think it works out that she chills there now and does things on her own. As she said, she can keep tabs on the others.
