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.
At this time, both Greenlee and Aidan proclaim their love for one another and promise each other that they will have the life they both wished for, before parting ways.
With the discovery of the blueprints of an underground bomb shelter, Aidan and Kendall are able to save Greenlee and Zach with the help of a young man calling himself Quentin, better known as Frankie Hubbard.
Aidan, Jack and others all pray at Pine Valley Hospital for Angie Baxter Hubbard to save the lives of Greenlee and Frankie.
Greenlee is discharged from Pine Valley Hospital and both she and Aidan are thrilled to finally start the life they dreamed of for so long.
Just when things are blissfully happy for the couple, Zach Slater sends Aidan on a rescue mission to Darfur to get a doctor out.
However, during Jesse and Angie's wedding, Greenlee finds out from her father about Aidan and Kendall's one-night stand.
Aidan sets out to win Greenlee back and remains persistent to ask her for her forgiveness and give their love one more chance.
The two give their love another chance, and Greenlee asks Aidan to take their relationship slow so she can earn back her trust in him.
On their honeymoon, Greenlee, who was affected by a tainted bottle of Bella, tells Aidan that she wants Ryan's baby.
Afterwards, he tells a construction team to stop working on the house he was having built for Greenlee and shows up at Ryan's with a gun.
Though he knows it means nothing, Aidan apologizes, stating that he never meant for events to turn out like they had and he has indeed changed for the worse since Greenlee's accident, and explaining that he wanted to make Kendall feel the same pain he did.
