Question
Before the part when JoJo and Bill "break-up," I could swear that she tells him excitedly something about her sister and her husband being out of town and that she and Bill could use their apartment for the weekend. (Then Bill gets angry and tells her he wants a commitment before having sex again).
I thought JoJo only had two sisters - who are both single and live at home? Was there a fourth sister introduced at another part of the movie?
