Here's a drabble I just wrote, Andromeda's POV, spoilers for Deathly Hallows. PG-13, I suppose.
Ted AND Dora? It simply cannot be...
Andromeda had been inconsolable ever since she found out the fates of her husband and daughter. It was as if a weight had been placed upon her chest, crushing her and keeping the oxygen from reaching her heart.
She looked over to her left, and saw George Weasley still sitting by the body of his twin brother Fred. The young man looked just as broken as she was, and the light had left his eyes. She knew his pain, as it was exactly what she was feeling herself.
Suddenly, she knew what to do.
She left the Great Hall and, even though it took a while, she found the item that she was seeking. Setting it for the appropriate amount of turns, she felt herself go back in time, and felt quite dizzy as it happened.
Finally, she was where she needed to be. She only had a few minutes to execute her plan.
Sneaking around the castle until she found the spot she was looking for, she crouched in the shadows a few feet away, and waited with her wand drawn. Soon, she heard the familiar voices of the past.
Percy had just made a joke, and Fred's lips began to move...it was time.
"Expelliarmus!" she cried out, lunging forward as Fred was sent across the room to where the others were.
Within a split second, she felt something raining down upon her, and everything went black.
Andromeda's Choice: To sacrifice herself so Fred could live, and she could be reunited with Ted and Tonks.
