The Hufflepuff Boys, although not born at the same time in this augmented universe they are.

Theseus and Newton are brothers and best friends with Cedric.

You are a new student at Hogwarts, and you have not found your group yet. And one day you're walking in the halls alone as usual. And you run into Newt, Theseus, and Cedric. Thesus, Cedric, and Newt are having an incredible time laughing and bantering with each other about Quidditch.

You accidentally run into Cedric's back.

Cedric: Hey! Are you ok? Helps you pick up your books

Newt: Y-you are new, are you ok?

Theseus: Be careful, and who might you be?
