Being Remus’ twin sister, but Sirius' girlfriend would include...
-when he found out that Sirius liked you, he was grossed out
-and very surprised
-and overall, got really protective
- “Okay, well, you can feel that way, but never, ever, will you be able to date her”
-spoiler alert: you guys dated
-after your first kiss, you just said “shit”
which was followed by a cocky Sirius saying “what, is wasn’t that bad, was it?
-because how are you gonna get away with this?
-when you both told Remus, he was just like “Nope,”
-he kept going on and on about how Sirius was an effing womanizer and that you are just setting yourself up to get hurt
-and you were just like “Okay, cool, but I think we all know that if he did hurt me I would just kick him in the balls and dump him so boom, problem solved”
-this is followed by Sirius staring at you, smiling, because he thought that was so hot
-and Remus just storms out
-later, when Remus realizes there is nothing he can really do, he kind of just sits next to you by the lake one day and takes an easier approach
- “I just- you’re my sister and he is one of my best friends. You can understand how that’s weird for me. Just be careful, alright? Men can be real wankers,”
-and for the rest of your relationship with Sirius, it was smooth sailing
-Sure, Remus got weirded out or protective sometimes
-but you were happy, and that’s all he ever really wanted for you anyways
