For what she said "I just heard you were a little down lately" it seems like someone else told her, she would have said it in another way if she got that from Mike's phone. If Lucy sent messages to Sandy (like some people think) from another phone, wouldn't it be illogic that she trusts in an unknown number sending her a message and talking about her boyfriend? Instead, that would be creepy. If Lucy told Sandy it was her, would she trust her knowing she was that agressive friend that always hurt him?
