Samuel Polk is another one of those characters I made up to fill a specific role. I needed another teenager who could drive, and so I named him Samuel. Now, you may be wondering why I had a character named Sam in Across the Stars, and a Samuel in The Experiment. I obviously like the name, but why? That can be answered in two words: Samwise Gamgee. He is my favorite character from Lord of the Rings, and so I started to like his name. I can't very well go around naming my characters Samwise, so I decided on a different name that can have Sam for a nickname. So Audrey called him Samuel.
one point in the story, I decided to write a chapter about Samuel,
simply because I didn't know what would happen next to the Raingolds. To
do this, though, Samuel needed siblings. I have a little notebook full
of fictional families I've made up, and so I looked through that to find
a Samuel that would suit the part. I couldn't find very many Samuels,
but I did find one family that had one with several older siblings, a
twin sister, and a younger brother and sister who were twins. These were
the Polks. I decided to use this family with a few alterations. For one
thing, I never mention whether or not there are any older siblings. For
another, I changed the ages of the girls so there were no twins. Then I
had the Polks as can be known from The Experiment: Samuel, Samantha, Timmy, and Tabby.
part in the story expanded slightly from the tiny chapter I wrote while
stalling the Raingold part. Their chapter doubled in length, and Tabby
had a role to play at Courtstone. Their main role, however, is to show
that these events are happening to others, and to expand the Raingolds'
acquaintance. And that role they fulfill very well.
