4x8 - Girlfriends

After Brock invites Joan to join her for a weekend in Las Vegas, she is convinced that he plans to pop the question. She brags about this constantly to her friends, but isn't so sure that she is really ready for marriage. She drives Brock crazy as she constantly makes him turn back to Los Angeles and then toward Vegas again, and even after he says that he is anxious to marry her, she continues to battle cold feet. Meanwhile, William carries around a baby doll to try to prove to his sister that he can handle the responsibilities of caring for a child.
