Sam in that white button-down with his sleeves rolled up being all bossy with Rowena and exchanging little knowing smiles with Dean. I’m here for this.
*rolls up sleeves* are we doing the zutara debate? let's do it. i saw katara as a sister figure to zuko. in that last agni kai, he's facing the sister who was never a sister to him, with katara (love interest of aang, who would soon be his best friend) who took him in and decided to believe in him even when zuko had proven that he didn't necessarily deserve it. then it's almost as if katara fills the place of azula in his story, and katara helps him defeat his sister and they end it side by side
