When Robin Jones comes into Billy's office at the beginning of the scene where they start kissing, she leaves the door open. Robin Jones and Billy start kissing but never close the door, but when Georgia walks in on them, the door is closed.
Billy: Georgia? I thought you quit?
Georgia: I quit my job. And now I quit you.
