I need some guidance on a specific conundrum I'm facing with two characters in a script I'm writing.
To give you some context. The story centres around a family in the late 1930's living in a small town and continues until post WW2. There is groom on the family's Estate that has a very strong relationship to my central character. Now as my central character embarks on his journey of discovery post World War 2, this is where I'm caught in a conundrum. This groom is valuable to the story as he is a secondary father figure to my protagonist and also a close confidant.
Do I elevate this minor character into a prominent character for the rest of the screenplay or should I keep him in a minor role / sounding board / confidant role?
Most of this 'Grooms' role will be off screen (through letters and telegrams) as he stays behind to help look after the family estate while my protagonist goes on his journey of self discovery.
Your guidance would be really appreciated here. I need to know how to develop this character while off screen or if he should stay ambiguous to the viewer?
