Okay so this probably isn’t the most important thing but its the thing that makes me happy. They are in a triad and its not a big deal! The Doctor isn’t making a big deal about it. They don’t feel the need to quantify their relationship to a complete stranger. They are just dating. Luna is Harry AND Hermione’s girlfriend. I love fic where poly relationships are treated with the same acceptance couples are shown. It makes my little heart happy so thank you 🙂
