These two folks have been friends with the Prince of Wales since 2005, when they all started at Oxford University together.
Amelia "Mia" Reede
PB: negotiable; idea would be Emma Stone - 24-25
Mia is snarky and talks a mile a minute with no communication filters. She says what she thinks and if you don't like it, tough. She studied English at Exeter College, where she met Alex. The reason they ended up friends? She was one of the few girls who treated him normally.
Samuel "Sam" Barrett
PB: negotiable - 24-25
Honestly, I don't have much in the way of ideas for this guy, except he and Alex met while a member of Out of the Blue. What is that? It's Oxford's best male a cappella group. Because singing guys = hot. Anyway, yeah. I see him as being similar in personality to Alex; they probably got in trouble together at parties...
