Naw it is cool. I took the liberty of advancing Amelia to Head Girl because quite frankly, that would be something she'd pursue and work hard for, especially with her parents pushing her to do so. This also results in Amelia being a little distant from everybody because she would opted out of some social events due to Prefect and Head Girl responsibilities. This makes the Wizard Pilgrimage important to her because becoming an Auror can truly be a distancing experience.

Also added some explanation behind her appearance.
