Julie tells Susan and she confronts Mike about it. He admits he doesn't want to press charges. He tells her about how Mary Alice and Paul killed Deirdre because of Zach. He's interrupted by a call from the police -- they've just found Zach. He's dead. Since Paul is missing, Mike and Susan go to the morgue to identify his body. Only it's not Zach. When Susan sees Mike's reaction, she realizes what he was about to tell her - Zach is his son. She freaks out and leaves him there.
She shows up at his house later to tell him that she's so happy he has a son since he always wanted children. But she can't let Zach near Julie and so she decides they can't move in together. She runs off in tears.
