Early LifeEdit

Aidan was born in 2128 (In Between Days:Reversal).

He was assigned to the Enterprise while Maximilian Forrest was the captain, and was retained by Hoshi Sato (mirror) when she declared herself Empress of the Terran Empire (In Between Days:Throwing Rocks at Looking Glass Houses).


Aidan was with the Enterprise and then the USS Defiant (NCC-1764). He worked in Tactical, often on the night shift, and was considered second only to Douglas Jay Hayes Beckett in terms of talent (In Between Days:Reversal).

In 2155, he was forced to compete for a position heading Tactical, which would bring with it a promotion to Lieutenant commander. He and Chandler Masterson (mirror) lost to Douglas Jay Hayes Beckett (In Between Days:Paving Stones Made from Good Intentions).

In 2157, due to disobeying the Empress's orders and generalized cowardice and incompetence, Aidan was demoted to ship's babysitter, an act intended to humiliate him (In Between Days:Reversal).

Personal LifeEdit

In 2157, he carried on with Jennifer Crossman (mirror), often meeting her in secret. When she was abducted by Calafans, he fought Chandler Masterson and won, thereby also winning Chip's girlfriend, Deborah Haddon (In Between Days:Reversal).

Later that year, he was seduced by the Empress, as she was looking for a father for her second child. As the ship's babysitter, he was expected to care for his own child and any other children Hoshi might have. This included Jun Sato, the son of time traveler Richard Daniels. He was further expected to perform any number of menial tasks, including exterminating a rodent infestation (In Between Days:Brown).

In early 2161, he, along with Chip, Lucy Stone, Andrew Miller (mirror) and Josh Rosen, conspired to get off the ship, intending to take Aidan's son, Kira Sato, and Chip's two children, Takara and Takeo (In Between Days:The Conspiracy).

He met Douglas Jay Hayes Beckett's ex-girlfriend, Susan Cheshire, when he was tasked with hiring a teacher for the Defiant, to instruct the Empress's children, later in 2161. During a temporal dislocation in 2178, he and Susan met in secret, as the Empress did not approve (In Between Days:Temper).

Memorable QuotesEdit

"I want to talk to someone who knows about more than just conquering things. Someone who's read a book or two. And maybe kiss that woman a few times, too. And more if she'll let me. Will she?"
— (In Between Days:Temper)
