Aurora Evans, Lily's sister, was the co-drawer of the Marauder Map and one of the few people Regulus trusted. After getting a glimpse of the trajectory of her destiny, she rewrote the ending twice - the first time she sacrificed her soul, erasing her own existence, in exchange for the integrity and peace of world A; when she woke up again in world B, she walked to the stage as a French cousin, rescued Harry from the cupboard, served as a teaching assistant at Hogwarts, and took back her life from dementors, curtains and the edge of the tower again and again.
It wasn't until the two worlds met due to the magic circle that all the memories and sacrifices were recalled again. People finally understood how this red-haired and blue-eyed witch exchanged two unknown rescues for what they have today.
And the big dog who always surrounded her was finally able to embrace his lost and found fox bride, never to be separated again.
