Second born out of five, Callaghan grew up quick to help take care of his siblings with his older brother, Amias. While Amias was the one who did most of the housework, Callaghan worked hard to keep food in the house, going to the store on his own most times. When Pascha was old enough, the two started going together. Callaghan never hesitated to throw himself in front of his brothers to protect them, and unlike Amias, was—and still is—confrontational with people.

Throughout his teenage years and his earliy adulthood, Callaghan didn't have any goals to work towards and typically hung out at the strip club with his brothers and friends. It wasn't until he was dating Zaira that he found his passion in dance. He met Nico when he was looking for a dance instructor and the two have been friends ever since.

Together with Nico, Callaghan runs a dance studio where he teaches poledancing. He loves his job and is constantly striving to improve his skills. This leads him to injure himself every once in a while, but it's not bad enough to stop him from trying agian. Not even an 8-foot drop was enough to make him stop trying to learn new pole tricks.

Sometime after, Callaghan started to feel unhappy in his relationship with Zaira and eventually led him to breaking things off. He still lived with him and Amias but often stayed the night at the dance studio. After soem months, Callaghan started struggling with his feelings for Nico. This, eventually, led to him and Nico getting together—with the help of Nico's husband, Oran, and the two have had a happy partnership ever since and Callaghan is much happier.
