What if the Potter family survived the killing curse? Peter Pettigrew was sent to Azkaban when evidence was pointed to him and not Sirius Black. The Potter's were safe with no more threats and living a happy life.
The catch? Sirius Black has a daughter that no one knew about, not even himself, Sirius Black had a one night stand with Madison King and left the next day without a trace. Madison decided to keep Elizabeth a secret not telling anyone who the father was or that she was even pregnant.
Sirius Black was living a happy life with his friends and godson. Elizabeth and Madison Winter also live a normal life, Madison raised Elizabeth on her own with some help from her closest friends when she decided to tell them.
However, Haneul fifth year took a bit of a turn when she bumped into Sirius Black outside the train station when he decided to tag along with the Potter family, and days later her name was put into the Goblet of Fire.
