Now that he's back on his feet, Shylock wants to know why he can't just have sex with Rosa. He's tired of the whole "living together with a fierce gangster" thing. He doesn't want to live with someone who's going to kill him. He wants to go home and be with his family. He also wants to be with Rosa because she's his only option. He tells Shylock that Rosa is the only one who can save him from going back to prison. She's the only person who can help him get out of prison.
