Matthew McPherson will someday become Graham's partner in crime, but for now he's just a child learning to handle something ... not of this world.

I am looking for someone who can convincingly portray an early teenager (around 12-13 years of age) for this role. SO, slightly whiny, moody and angsty should be easy places for your voice to go. Matthew's teenage self isn't a leading role because after the first episode there is a time skip, but I will still be casting his younger and older self together to maintain consistency. I do not mean I am seeking to cast his younger and older self to the same actor — I will just be making the decision back-to-back. I want these roles to really feel like it's someone who was young, and has since grown up.

I will allow both male and female actors to try out for this role. If you think you can nail what I'm looking for, I urge you to give it your best shot.
