Ship: Romantic or Platonic
I haven’t talked about it very often, but I’m actually really defensive of these two’s dynamic and how they could interact shipping-wise. It feels too cheap to just reduce them down to the “hard-headed guys always arguing” duo which I see so often that I also reject. Even pre-redemption, it was Katara and Zuko that argued and clashed all the time, Sokka just subtly takes advantage of the situation.
Sokka and Zuko? Rarely clash and Sokka will back off with his jibes pretty quickly if confronted.
You know what they do have? Shared situational experiences and sense of responsibility to protect people. That’s not including how Sokka relaxes so much the first time they’re made to work together. He starts spilling all sorts of things he doesn’t normally talk about: mentioning Yue (which he rarely does to anyone), admits that he feels guilty and responsible for the failed invasion, and confesses how upset he is about the possibility of failing again and endangering those who relying on him. Zuko’s pretty patient with him and does his best to reassure (in his own awkward way) and insists that its okay to fail sometimes as long as you keep trying.
