Aidan comes to Pine Valley in 2002 after his aunt Anna Devane, a former resident of Port Charles (the fictional town in which the ABC daytime drama "General Hospital" takes place), comes to town. He is in "Special Ops" in England, and not much is known about him at first. He uses such training to spy on other Pine Valley residents for Jackson Montgomery and Ryan Lavery. Aidan was a soldier while in his home country. He is a Jack-of-all-trades: a construction worker on Erica Kane's penthouse after a fire guts it, and a bartender at the Valley Inn. Aidan becomes partners in a private investigators office with Tad Martin.
