The very super begining

When little sister of The Curtis Brothers is a witch things go south.
Maggie Curtis is the twin sister of pony boy Curtis. She is a greaser and Slytherin through and through. No one can believe it in her third year when Sirius black asks who she is. Cause no one doesn't know Maggie. They are both broken beyond repair and need something to fix them, and a greaser might need a blood traitor.

Outsiders and Harry Potter cross over. I'm playing around with the timeline though. The muarders are being pushed back to the 60's.
