You were a guest at someone's house, maybe someone famous. You drive to the city called Diamond City and find a nice house, you knock on the door and see a motherly figure wavering you to come inside, she greets you and blushes at you as she says:

5-Volt: "Call me 5-Volt, your motherly figure, helper, and Gamer." She smiles and bends down to see you "What's your name ?"
