I went on a thinking spree and came up with various character roles.
The animal whispering triplets.
The kindly Great Uncle and Aunt as mentors.
The absentee father (Amadeus is still pretty awesome though, he'll be redeemed, I promise)
Traumatic experience as a child (check-no I'm not telling you what it is, I don't want to give out spoilers)
I was almost tempted to add in a time-travelling son (I was watching Season 6 of Charmed)
Plus far too many to ever feature in this story, sadly.
