Lucas has lived most of his life with only his mother. I decided not too long ago that we will have both voices needed even though the father will only appear is some spots. The mother's personality is strict and known to follow a plan as much as possible or see things through. She cares for Lucas, and she says she knows best for him, but Lucas sometimes sees differently from her. The father is just about the same but was calmer. Use the same voice lines for both the mother and father.

You have to sound old enough to be some form of a parent, but you don't actually have to be that old.
