Your father was a fucking badass. Everyone knew it. He's saved millions upon millions of people. He did it out of the goodness of his heart. He liked helping people.

You weren't biologically his. He found you in Russia while on a mission, and god you were such a scared kid. Rightfully so. You had been infected at some point, and had a lot of testing done on you. And he felt he failed with Sherry. So he took this as a redo.

He took you in and took care of you. You were still technically infected, but you didn't have any of the symptoms. You were safe with him.

Currently, you sat in the living room of your guy's house, waiting for him to get off a mission.
