Cassie takes Josh to his car and for a second time Cassie tries to reach RJ on his cell phone. They hear his phone ring and find him asleep in Josh's car. Josh lets Reva know that RJ's been found. Josh sends RJ to Cassie's car and Cassie says that Josh should keep his distance from them for a while. Josh thinks he's offended her, but she insists it's to avoid having RJ become too dependent on Josh. Josh says that he's the closest thing to a father figure RJ has. She acknowledges that RJ had had Richard, then Edmund, and then Jeffrey. Josh reminds her that he's been the one constant male figure in his life and he needs to be around for the next loser boyfriend Cassie brings home. She semi-smiles at this comment. Josh tells her that he will always be there for Cassie and RJ.
Meanwhile, Reva has also called Dr. McCabe for help when she was looking for RJ. He quickly arrives thinking she has a medical emergency. She tells him that he gave her the chemo that made her sick, it's her fault she had to run to the bathroom, giving RJ the opportunity to wander off-therefore it's Dr. McCabe's fault RJ is missing. He refuses to help and starts to leave when she tells him he's all she's got. She reels off a list of places RJ might go, fun places. Dr. McCabe says that when he was RJ's age he'd wander off to the science museum to see the latest exhibits. Reva replies, "Yeah, well, you're you." After Josh lets Reva know RJ's okay, Reva tells Dr. McCabe that she's a failure as a woman, wife, and mother and that Dr. McCabe must get a perverse thrill watching all this. She tells him she has to leave to go knock some sense into her son.
