Tom's first appearance is when he's a young child. Tom does not trust John, a strange man who was taken in by Tom's mother, Sally, after being in an accident.
Years later Tom and his sister Becky return home to visit his mother Sally and his younger brother Jacob for Christmas. Tom and Becky take care of Jacob when Sally goes to a New Year's Eve party where she meets Owen Crawford. Days later when Jacob is taken by Owen, Tom and Becky eventually find Jacob and bring him back home. Tom then comes up with the idea that they tell the Army that Jacob died in a fire to protect him.
Tom wants revenge on Owen after what he did to his family by spying on him. Tom is given the news that the Army have tracked down Jacob but were stopped. Tom then moves Jacob to a safer location.
When Tom feels its safer for Jacob to return home, they go to see their mother, Sally, who is dying of cancer. After Sally dies, Tom tells Jacob that he should tell the world about his abilities but Jacob refuses and says it won't be a good idea. Tom begins writing books about their existence of aliens and UFOs. During a TV Interview Tom is asked if he can reveal what made him a believer but refuses to answer the question, leaving Owen's son Eric Crawford wanting to know what made Tom change his mind. Tom later finds out that his sister Becky is having an affair with Eric. Tom persuades Becky that Eric is doing it to find out the truth about Tom changing his mind. Tom then later gets together with a group of people and confront Eric while he and the Army were moving evidence of the Roswell crash. All the evidence then disappears when a spaceship takes it all away.
After the death of his brother, Jacob, Tom is determined to protect his niece, Lisa, from Eric Crawford. Tom tells Lisa the truth about her father being half alien and the powers it gave him. Tom is then in the hospital with Lisa after she gives birth to her daughter, Allie.
