Okay but Sirius and Lily who had an extremely close sibling-like bond? Like, full on big brother-little sister dynamic between them.
Sirius and Lily who are mean to each other, calling each other names and picking arguments over the stupidest most insignificant things, only to turn around and be laughing and joking together not even twenty minutes later. People will genuinely think they can't stand each other, but really they're best friends who will always have each others backs no matter what.
Sirius and Lily who can be open and vulnerable with each other in a way they can't be with their other friends, because they're the only ones who know what it's like to watch your relationship with your blood sibling crumble right in front of you. They're the only ones who understand the grief of that, the anger and regret, how it feels to have so much love for someone who won't accept it anymore.
Sirius and Lily who give that love to each other instead. Who help each other move on, who listen to each others thoughts โ no matter how cruel or selfish they might sound โ without judgement. Who remind each other that it's okay to hate them, or miss them, or wish they'd never been brothers/sisters at all.
Sirius and Lily who both understand that blood isn't always thicker than water. Sirius and Lily who help each other learn to be okay with that, because chosen family can be more loyal than the one you're born into.
