Summary: Light years away from Earth and centuries after the Thames house and that event where no one could die, Jack sees a familiar face. A face he never though he'd see again. A face that doesn't want anything much to do with Jack except where it concerns their job--which involves two planets, a human government that doesn't want to get involved, a mineral, and an alien government that decides it wants to a playground bully again. It's kind of complicated.

A/N: Though obviously this is an immortal Ianto story, this isn't about why or how he's immortal. It's just a love story that features aliens and the Doctor. It's about two people who, though immortal, do what the rest of do at the end of the day: give it good try. Also, the opening scene is inspired by this gif. And though it does feature the Doctor, he's here more to get Jack and Ianto in a locked room to talk, so not a crossover really.
