Robert Chase, M.D. is the new face of the Princeton Plainsboro's Department of Diagnostic Medicine. He has everything he always worked for under the direction of Gregory House. He lost some of his friends just as Foreman, who is gone to another hospital in New York City. He wrote a diary while working to come to the terms with his work. These are his stories:

I was sitting in my office working on a new case I had. The lights were already switched off and it was already a long, actually a really long while after midnight. I didn't even notice the time because I was so pored over by this case. I was pushed to my limits by this case.

And suddenly I heard a knock on my door. As I looked up, there was no one at the door. I finally moved to the door to look if somebody was in the hallway. As I opened the door I heard somebody standing up just to the left of the door and I was shocked. The person who stood in front of me was somebody I believed to be dead! I didn't know what to say, I didn't even know what to think but I head one thought spinning in my mind: "Is this real? Am I dreaming?" I thought. The only thing I did was turning around and moving back into my door. He followed me to my office and sat down in front of my desk. "Nothing changed. Everything stood the same!" he said. "I didn't want to change it." I answered. For the first time in my life, I thought that he was impressed! He had a look in his face that I have never seen before and it really impressed me. He looked happy.

"I spent a lot of time in jail after this little incident." he said. I started to doubt my own thoughts. Did he really change? I guess not. "Chase! I lost my friends, I lost my life and I lost everything I ever had! Wilson's dead! Cuddy is gone and I don't have a job because everybody thought I was dead!" he said. I didn't know whether to offer him a job or to just kick him out of my office for everything he did. "House, you shouldn't have come here at all!" I said. "Chase, I know I did things wrong but I want to protect the patients from totally incompetent doctors around here. I'm not telling names but we all know who I'm talking about, don't we?" he said that with his normal ironic and sarcastic voice which we all hated. "House, stop that. You don't even have a license anymore. And you're coming in MY office wanting your old job back? It's a little optimistic, isn't it?" I said. "We'll see", he said as he left my office. I was hoping he wouldn't come back.
