Made a character for your book Numb3rs. Never seen the show or anything, I know very little about all of this. But I was bored so I hope you can include my character. Feel free to change anything if you want.

Retired FBI agent
Simon Jansin is one the greatest FBI agents in history. He is Alan Eppes's best friend. He is now retired hates having anything to do with the FBI and stays in his house 24/7.
His main role is mainly comic relief. He is the funniest character in the book. He has brief appearances in his house when he is visited by Emma and Don. They try to get him to help them with whatever they do in the book. The rest is up to you! I have never seen this show I don’t know any of the characters but I hope Simon can be in your story.
