okay so hear me out:
nine/rose spy au.
nine is legendary in the espionage world. there he is known simply as the Doctor. no one knows how he always manages to get out of the worst situations unscathed and with the necessary mission accomplished but he does. one day he tells the powers that be that he’s out, done with the spy game. the reason being he fell in love and he will not endanger his wife-to-be.
fast forward a few years and his wife is still unaware that he used to be a spy. they have a daughter and they’re happy. nine has to go on a business trip for the software company that he works for now so he kisses them both goodbye and promises to be back in a couple of days.
when he returns it’s to his worst nightmare. they’re dead, a message to him painted on the walls in their blood. someone thought he had information they needed from his spy days and had decided to use his family as leverage to get it from him.
nine packs in all of his emotions and grief and becomes the Doctor again, setting out to find whoever had taken his world away, needing to make them pay. this time though, he’s rogue. his old boss tries to bring him in but he won’t have any of it. this is a revenge mission, straight and simple, and he’s not going to deal with the company’s rules.
the revenge mission leads him all over the globe and he keeps running into a blonde who’s always after the same information he is. he suspects the company sent her to keep tabs on him but it frustrates him because he can’t figure out who she is or ever guess what she’s going to do next.
when a vital source slips away because they were both going after him in different ways they finally agree to work together instead of separately in order to get the people who killed nine’s family.
i know spy aus been done before, i know. but i love aus that have nine and rose both walking that thin line between good and evil, straying off of it in either direction as they’re wont to do.
because this journey they’re undertaking through the glitz and corruption of upper class society and the dark grimy corners and alleys of the worst parts of town is a long and twisting one. they’ll eventually succeed in their mission but it takes years to get their chance at the person who killed nine’s family.
a lot can happen in a few years. there’s a growing respect and admiration between them. there are argument born from their different operating methods and personalities. there are poisonous secrets kept from each other. guilt complexes and overwhelming grief and ill-timed moral crises. there are days in the sunshine where things look hopeful but they’re few and far between. through it all though there’s this spark of chemistry that they’re both ignoring because it can’t mean anything, a burgeoning feeling of love in her chest and a fragile flower of hope and light starting to bloom in his, both ignored in favor of chasing revenge.
