Please try and be able to do a younger/older type of voice depending on which Aubrey it is. Older meaning around 16 and younger being around 12.

Aubrey in the dream world is very cheerful, sassy and emotional. Emotional more so when Basil goes missing, but with a little hope and convincing she'll be right back to her cheery self. She is often seen bickering with Kel. 

In the real world Aubrey is violent, temperamental and unstable. Crying and yelling is quite frequent up until the end, when she becomes less mean, more understanding and civil.
