Esteban waits for Marina to wake up while she lies in her room, surrounded by bypass machines, being dead.
Cuddy stops by House's office. She finds him staring at the Whiteboard and thinking. Apparently, kidney failure makes House horny, as he claims that the security light looks good on her legs. Cuddy thanks him for the compliment and asks him when he's going to tell Esteban that Marina is dead. There's no reason to keep her on the bypass machine, especially when they don't have medical insurance and bypass machines look pricey. House says he's sure Esteban would prefer Marina alive, and Cuddy accuses House of being a hopeless romantic who wants to give Marina and Esteban's story a happy ending. House says he doesn't care about them. Cuddy wants to believe that he does, but he firmly says he doesn't, and I see no reason to doubt this. What he does care about is solving the mystery. He doesn't want to discover that they missed a way to save Marina during her autopsy. "It's time to let go," Cuddy says.
House finds Esteban praying in the chapel. He's surprised to see him there, as he was "told" Esteban didn't believe in God. Who told him that? And why? And how would House, who can't remember patient's names, remember that isolated fun fact? Anyway, Esteban says he doesn't believe in God, but he told Marina he'd do everything he could to fix her, and this counts as everything. And it's not like he has anything to lose at this point. "It's not working. She's not coming back," House says. I like how he managed to blame either God or Esteban's crappy praying abilities on Marina's death there. House tells Esteban to come to the ICU and say goodbye to Marina while House takes her off the bypass machine. Then we get a look inside House's personal nightmare when Esteban sobs and hugs him.
