Please watch this amazing Zutara. It made me giddy. (Update; the OG post is from Twitter this person just reposted it on tiktok will add the OG link once I find it)
I know a lot of people think Zutara is a bad boy/good girl ship, but those people are so incredibly wrong. If anything, Zuko would be the stickler for rules in that relationship and Katara would be the rabblerouser (can we start using the word rabblerouser again? It's fun to say). Katara in canon started a prison riot and committed eco-terrorism. Zuko- while he was on the wrong side of the war- did not make a habit of breaking rules until he felt he had no other choice. The most bad boyish thing he did was helping Jet steal food on the ferry, which...guards, arrest those starving children immediately 🙄. Everything else he did (going as the Blue Spirit to rescue Aang, defending that EK family from those thugs, helping Katara find Yon Rah) weren't so much "bad boy" behavior as they were the desperate last acts of a guy who actually did want to do what he thought was right. Occasionally misguided and impulsive acts, sure, but they weren't inherently rebellious like when Katara literally punched the patriarchy in its face.
If their friendship and romance had been given more room to breath, I bet Katara would have gotten Zuko into a lot more trouble than he would've ever gotten her into. And he would complain the entire time but secretly he'd love being included. The only thing even remotely bad boyish about Zuko is his character design, but that's prejudiced thinking. Not every shaggy-haired youth with a tragic backstory is a rebel without a cause. And just because a young heroine is bright-eyed, willowy and nurturing doesn't mean she's above literally blowing up your spot if you cross her.
