So, Ginny is... Ginny. I like to think my version is pretty true to the canon version (except that mine does not become Harry Potter's brood mare because, you know, not all high school relationships last forever).
She's feisty and brave and a pain in the ass, but she's also thoughtful and kind a good deal of the time. She feels things very deeply and she's not very easy to boss around or ignore. She stands up for herself, but she stands up for other people even more often. She believes in good and evil, black and white, light and dark, and she always tries to stay on the right side of those lines. She triumphs mightily or fucks up spectacularly and often feels like she's never somewhere in between (even though she is, because we all are). She loves her family and her friends (including Harry) and would do anything in her power to keep them safe and happy. She once fell in love with a boy named Tom Riddle because he seemed lonely and beautiful and knew just what to say. And she loved a boy named Harry at first because he was supposed to be a hero but later because he so obviously needed someone to save him.
She's just Ginny. Somewhere I have a twenty page app where I analyzed and examined every action she made in canon and every action in my personal headcanon since then, but I'll spare you.
She plays Reserve Chaser for Holyhead and she's going to come to town soon to stay. Plot with me.
tl;dr Becca has a lot of feelings about Ginny, let's plot.
