Lally and Theseus were the perfect couple.
A teacher and an Auror, the ones who'd always be rational and smart, knowing exactly what to do all the time, giving you the answers, teaching you to defend yourself and letting you visit Aunt Tina and Uncle Newt, although Theseus was a little skeptical letting his eldest child around all those creatures.
Lally's features were much more pronounced in your apperance, Theseus looking as if he might as well have been your adopted father, since you two looked nothing alike, except for the fact you two were the same in attitude, Lally rolling her eyes at your quick comebacks and retorts, just like he did.
You were going to Hogwarts, now with your younger brother. Much to the teacher and student's amusement, you two would dance in the Great Hall when it was empty, as if you two had been partners to the Yule Ball and were now flautning your grace and talent when it came to sliding across the floor.
Arriving home for the summer, you heard one set of footsteps to the door. Lally, or Theseus?
