Aidan was originally a special constable on the housing estate of Goldsworth Park in Woking. He met Angie Lake in college, and they stayed good friends. When Angie came to a party with the Inspector one night, he grew curious and followed them to the BOOTH. At first, the Inspector was reluctant to travel with Aidan—he felt his name was too similar to Aiden—but eventually tolerated his company. After many adventures together, he and Angie grew closer and eventually married.
"Let's Kill Hitler"Edit
When the BOOTH lands in 1933 Germany, Aidan disobeys the Inspector's orders not to interfere with history and heads off to kill Adolf Hitler. With the dictator dead, they return to the early 21st century and discover a peaceful world, with happy people everywhere. The Inspector admits Aidan's actions have created "heaven on Earth". Unfortunately, on their next trip into the future, a Blorgon Battlehub arrives and annihilates the now-pacifist planet. Aidan understands that the consequences of time travel are not always obvious, and the Inspector regretfully takes him back in time so he can stop his previous self before he changes history.
