Ethan and Fawn, The Lost Potter twins

Harry was a well-known person and one of the people to have known to survive the killing curse that took place when he was no older than 2 years old and his younger siblings being a year old. He and his siblings were kind of close.

Though, on that faithful night when both the twins turn but a year on there shared birthday, they all were knocked unconscious and all given a scar. Harry's being the famous lighting strike, Fawn's being a doe, and Ethan's being a moon. When both the older and younger siblings were taken, they were broken.

The twins thankfully got to go to the wizarding world but Harry didn't. He had to stay with the Dursley's. Though, what they all three DON'T know is that James Potter was disloyal to Lilly and had an affair with SIRIUS. It is not common but not unknown for a male to get pregnant. The twins are both purebred pureblood witch and wizard. The twins also got the luxury of staying with the Zabini's family where they are treated like one the Zabini's family and the twins are both smart for their age which sometimes scares the Zabini's family.

What happens when they both got to go to Hogwarts a year early and they get put into Slytherin and Gryffindor? What will happen when Ethan and Blaise get protective of her and Draco starts falling for her? What about when both Ethan and Fawn find out the truth?
