Doctor Frederiksen went through a variety of changes to get where he is in the story. Originally, he was named Dr. Theodore Nathaniel Hayes, and he was going to be the classical Freudian style psychiatrist with a gray suit, glasses and a beard. As his needs changed for the story, he dressed less down, and his beard was trimmed back to just his chin. It was an attempt to make him more modern and relatable to the patients he worked with, particularly children. His name was changed because I saw a character on a television show named Theodore Hayes, and I didn’t want to copy them. So, his name was changed to Viktor Anthony Frederiksen. For the longest time, I was going with Viktor Frederiksen, but decided that it sounded too much like Victor Frankenstein, and gave too much of the plot away with just his name. I ended up using the middle name as his first name, and Doctor Anthony Frederiksen was born.
