Yeah! Amber and Scorpius were in the same blood circle. Maybe they saw each other at charity events and such? And yup! Same house but different year. :) I'm sure Amber would look up at Scorpius since he's smart and since he's working in the ministry too. She'd totally let him (and only him) get away with petting her on the head.
Aw! It's cute that Scorpius reads Dom's column! :) Dom's a bit older than him but they were at Hogwarts together for a few years and he's a Malfoy so I guess she'd be familiar with him anyway.
