"Why are we here so early?" I cried as I walked into the office seeing Cameron there already. I was tired, I forgot how much energy 4 hours of sleep doesn't give you.
"Why? Been busy?" My boss, House called, "Have someone round last night?" He wiggled his eyebrows suggestively.
"No. But 4 hours of sleep do tend to make someone tired." I retorted. He looked curious and went to open his mouth but was interrupted by my other colleagues entering the room.

"Male, late 30s, seems to be dying with no apparent reason. All the test have come back clean, but he's still dying." House told us all. We looked through the file and after some deliberation we split up. Me and Chase to the patient, with Foreman and Cameron off to book CT's and MRI's.

I followed Chase in but stopped dead when I saw who our patient exactly was.
"Morning. How are we feeling today?" Chase asked. I stared in shock, he stared back. Chase noticed he wasn't answering and followed his eye line back to me.
"You two know each other?" Chase asked, looking slightly shocked. I wasn't surprised, only a few knew what my life was like before I joined PPTH.
"Dean-" Before he could finish, I ran out the room at full pelt. I head shouts following me, but I paid no mind. I knew what was going to happen. He'll call him. I knew he would. I couldn't face him not yet.

Third POV.
Back in the patient's room, Chase and the patient stared at the door in shock. Both having never seen her react so emotionally. Chase turned back to the patient.
"I assume you knew her then?" He asked the person in front of him.
"Yes. I am or rather was a family friend. She doesn't get on with her remaining family, whereas I'm good friends with them. It's… complicated."

"Oh no, its fine. We just don't know a lot about Dr. Winchester's background." Chase responded, trying not to seem too eager. "Now, I just need to take some blood to run a few more tests. Is that okay Mr. Novak?"
"Yes that's fine. And please. Call me Castiel, or Cas."
