The group left the Room of Requirement, having mandated Ginny stay. The fourth Weasley child trailed behind a moment. "Ginny, I love you. Be as safe as you can and," she paused, "show them how Weasley women are strong." With that Gwen Weasley slipped out to join the Battle of Hogwarts.
Ginny sat on the Great Hall floor now, her beloved older sister's lifeless head in her lap. Her sister, who had blasted out the staircase, killing a group of fourteen Death Eaters including the Lestrange brothers. Who had brought down the staircase knowing she would be crushed by the falling rubble as well. Show them how Weasley women are strong. So Ginny fought harder.
Gwen, who lived and loved and laughed. Gwen, who taught Ginny how to stand up for herself. Gwen, who taught Ginny Quidditch and passed on the subtle way of pranking. Gwen, who had wanted to be a Defense professor. Maybe Ginny's dream of professional Quidditch wasn't so great.
Gwen, who had always listened to Ginny without judging. Gwen, who had responded to Ginny's quiet admission of being so deathly scared of dying and having her family die with an, "Oh, honey. I hope that you don't have to face the reality of that fear anytime soon. But when I die, in this war or later, I'm going to join the ones I love who have already passed and wait for those who haven't to finish long, happy lives and join me." Gwen wouldn't want her to grieve too long. Show them how Weasley women are strong. So Ginny let the wound close a little.
Gwen, who had taken a 6-year-old Ginny from the wreakage the twins had made of Ginny's carefully constructed grass town, dried her tears, and told her, "now it's time to rebuild". Gwen, who had cried when Cedric died and cried on his birthday every year since and maybe never really dated again, but still started glueing her pieces back together and kept enjoying life. Show them how Weasley women are strong. So Ginny started to rebuild Hogwarts and made plans for school in the fall.
Gwen, who always picked Ginny up when the brothers pushed her down. Gwen, who had always told Ginny to be her own person, follow her own dreams, blaze her own path. So Ginny picked up her broomstick. Gryffindor needed their chaser. And if years later, when Ginny Potter-Weasley played for the Holyhead Harpies, a Gwen Weasley scholarship for Defensive Magic courses was formed the same June as the Cedric Diggory Seeker's Summer Camp, no one batted an eye.
Somewhere in heaven, with Cedric and all her lost friends around her, Gwen Weasley looked down and smiled.
