I didn't expect you to, I'm just not braining right now. XD But yeah, basically Ally writes music for this very out-going kid who is kind of dumb teenager sometimes and very energetic, but also really passionate and serious about his hobbies. Or. I don't know how to describe him. |D But basically, he has Amelia's passion for things and general gusto for life and it clashes with Ally's shyness and rule-following; but also compliments her own passions. Buuuuuut Amelia and Ally don't have music in common, so I feel like Ally'd have more of the "I am perpetually baffled by you and also you probably shouldn't be doing that" with Amelia.
