[There's a huff of laughter at that. Knocking sense into people. Sounds about right. As he listens to Zuko detail how the Avatar gang worked together and how they'd operate here it just makes him miss the Big Hero 6 even more. He knows how all of his friends would be able to help if they had working gear and how they'd react to this situation…assuming they'd all be on the same side. This world sucks.]

…sounds like you've got a lot of good friends back there. [He frowns in thought.] There's gotta be somebody else who knows how to do this earthbending thing, or someone who can examine the machines like Toph can. Maybe the natives know something? They've been using magic for centuries. Someone suggested flinging dirt and grit into the machines to slow them down but I don't know how well that's gonna work. We need to brainstorm some more.

But that's a good place to start.
