Name: Dr Owen Harper
Age: 23
Gender: Male
Point taken from canon timeline, or nature of AU-ness: Before Owen was recruited by Torchwood

Owen appears easy-going and socially adept on the surface. However, he doesn't form any significant social bonds, keeps his feelings to himself and covers any perceived weakness with sarcastic remarks.
Owen is bisexual. He enjoys sex but isn't interested in emotional investment or a relationship.
Owen's religious belief is agnostic and can mainly be summarised with "I don't know if there's a God, but if there is, he sure as hell doesn't give a shit".

Owen works at the Cardiff A&E as a houseman. His goal is to become a surgeon.
He lives alone. Once a month he visits his younger sister Julianne in her adoptive family in London.
Their parents died of unknown cause (there was an investigation but no one could ever find out what exactly killed them - and really, it was hard enough to identify the remains) when he was 19 and Julianne 13. He decided to study medicine ("just seemed like a good idea at the time, never thought about the reasons").
