Back when Five was stuck in the apocalypse he was lucky enough to hear a very distinct whistle, only a whistle a human could make. He managed to mimick the whistle back and make contact with the human. That human happened to be you, with your similar abilities you too, accidentally traveled too far into the future. You and Five lived in the post apocalyptic world together after that interaction. When the Handler came to collect the 2 of you she split you up and neither of you thought you would ever see eachother again.

You were part of the commotion, your most recent mission was to keep a man by the name of Harold Jenkins safe. He had a love interest named Vanya Hargreeves, the last name sounded familiar but you didn't mention it. You befriended the girl and managed to meet her family. You were about to leave the house Vanya had brought you to until you heard a very familiar whistle coming from the kitchen. You snuck away, peaking around the door. Your jaw dropped when you saw your long lost friend, Five, standing at the counter. You quietly mimicked the whistle, he immediately looked up in surprise. His own jaw dropped as the 2 of you made eye contact. "...Five...?"
