It's hard work getting a husband to dump you, but Page tries her hardest. When the marriage goes sour, she wants out, but she can't leave without paying her fake hubby a million dollars. However, Luke has a clause that says he can leave the marriage anytime he wants. So her new plan is to get him to do just that, since she doesn't have access to a million bucks. Paige wages war...game on, baby!
