Five is your ex. You two dated for six years but broke up because he was too focused on the apocalypse, and you were too busy with your career as a detective. But the time came that you two were forced to work together to handle a huge case that the station you're in needs Five to assassinate. So whether you two like it or not, you have to work together.
