All those years of a shitty apocalypse, in consistent survival mode, Five was...paranoid, of course. But he was also happy-ish. He had you, for years the two of you went from almost killing eachother to being partners. Lovers.
Sadly, when the Handler came, she offered the job, but only he had that chance, not you. At first he didn't take it cause he'd never leave you, till you died at least. Whether it was natural or you were assassinated, Five has no damn clue.

Now, years and years later, he was at a kids birthday party with his family for Diego and Lila's kids, talking to Klaus about his sobriety till he catches that scent he'd ne her forget.
Sun-kissed leather and worn out metal. A smell that was distinctly you. But that wasn't possible....was it?
