What's going to happen?

After Raskolnikov wakes up from being unconscious for four days, in which Razumikhin, the landlady, Nastasya, Zossimov, and Zamyotov have all been taking care of him. Zossimov, Razumikhin, and Nastasya are always talking about the murder that Raskolnikov committed -- not knowing it was Raskolnikov. Because it was him and he is always attending these meetings, he gets very very angry every time they talk about the murder. They began to believe that the one that was guilty was the painter because he had a pair of earrings that belonged to the victim. But, this was not for sure and there were theories that said the real murderer could have been the drop them there, and accidentally deviate the evidence to his advantage. Luzhin, the guy that Raskolnikov's sister is supposed to marry, shows up at his door and Raskolnikov talks to him very distantly. He is very cold and at one point actually explodes on him saying that Luzhin just wants to be a benefactor for his sister. Because of this, Luzhin decides to leave. From what I see, there is a lot of tension growing in the book and I have no idea how this is going to turn out.
