When 2 Became 3

Lucius and Severus were 2 parts of three, forever looking for their 3rd. They never thought they'd find him but alas there he was. How would Harry take it? What would Draco think knowing one of his best friends was also his dads 3rd mate? Much drama, all of the cute. Some smut too, your welcome :p Also No Voldy and Snape doesn't work at hogwarts.
