Meredith and Derek got approved for the clinical trial and began looking for patients to take part in this experimental procedure. Of course all the patients taking part in it are terminal so they will die rather the trial fails or not.

"Remember, if you find it's too much for you to handle, I can do it on my own." Derek reminded Meredith before they entered their first patient's room.

"Derek, if it was too much for me to handle, I wouldn't had wasted my time doing the research and finding patients. I want to do this."

"Okay." Derek and Meredith entered the patient's room. "Mr. Robinson, Mrs. Robinson. Dr. Grey and I want to say how grateful we are that you've decided to participate in our trial. I know it's a hard decision to make."

"It is a chance, right? It's our only chance." Mr. Robinson said. " If the surgery doesn't kill me, the tumor will. What have I got to lose, right?"

"As we discussed, the treatment has never been tested on humans. We're going to inject a live virus into the tumor. We can't take the tumor out. Our hope is reduce the tumor from within." He said. "Do you have any questions?"

"No, Dr. Shepherd." Mrs. Robinson said.

"Dr. Grey, please run some pre-op tests on Mr. Robinson."

"Okay."

An hour later, Meredith gave Derek the results of Mr. Robinson's pre-op tests she ran. Derek sighed looking at the scans because the tumor is infiltrating the optic nerve. He and Meredith went back to their patient's room to talk to him and his wife.

"Mr. Robinson, I'm sorry, but I believe it's possible the tumor is infiltrating the optic nerve. We should consider moving the surgery. Maybe even doing it today." Derek said.

"What about you, Dr. Grey? You're a sexy little thing. Do you think, Dr. Shepherd here is attractive enough for my wife? Hmm?" Mr. Robinson asked.

Meredith had to remind herself it's the tumor talking, not him. She looked at the wife and saw her in tears.

"Jennifer, this isn't easy, I know." Meredith said.

"My husband is probably going to die today. We're moving up the surgery, and he might die. And all he can do is try to fix me up with other men. And I know I know it's the tumor talking. But, if he dies, my last memory is going to be of him calling me a piece of ass."

"Dr. Grey, please prep Mr. Robinson for surgery." Derek murmured.

"Dr. Shepherd. I hate this. Not being able to see. I just want to see Jennifer." Mr. Robinson said.

"Phillip, this is an extremely risky operation. You may have a few weeks to live; could spend that time with Jennifer. You don't have to do this surgery today. You can still back out. We'll understand." Derek said.

"I'm trying to fix Jennifer up. I don't want to leave her alone. That's the one thing about all of this I really can't stand. I just want her to be all right when I'm gone. You need to tell her that. Please tell her that."

Mr. Robinson was put under anesthesia, and Derek took a deep breath before he began the cut. He glanced over at Meredith.

"Ready?"

"Let's begin." Meredith said.

An hour into the surgery is when everything began to go downhill.

"Complete heart block." Meredith said, looking at the monitor.

"Damn. Injection went into the intra-arterial. Push one of Atropine." Derek ordered.

"Not responding!" Meredith said.

"Push another one. Come on, come on." Mr. Robinson straight lined. "Patient number one. Treatment failed. Call it, Dr. Grey."

Meredith sighed and looked at the clock. "Time of death, 19:33."

By week two of the clinical trial, Derek had killed twelve of his patients. He was getting frustrated, and so was the Chief. Richard had told them they should give up and to send home their last patient.

"Derek, she's a kid who's gonna die without surgery." Meredith said. "We're so close. I know we are. We can't quit."

"She'll die with surgery." Derek said.

"Derek-"

"You heard the Chief, Dr. Grey. And he's right. We've killed twelve people. I don't want to kill thirteen; surgery's over, we're done." Derek walked away.

"I never thought you were a quitter, Derek." Meredith shouted. "But I guess I was wrong about you, and now we have to tell a girl she's going to die because you won't perform the surgery because you don't believe in yourself."

Derek stopped. "If you can get it cleared with the Chief, prep Beth for surgery."

The surgery was a success, or at least a success as in she didn't die during surgery. Beth was taken up to her room to recover and Derek and Meredith talked to the parents, telling them the next 24 hours will be very crucial for her.

"She hasn't woken up yet." Beth's mother said.

"Sometimes it takes longer with brain surgery for the body to recover." Derek explained.

"But she could not wake up?" Beth's father asked. "Could she die?

"That's a possibility, but I'd rather not worry about that until we have to."

"But she's stable, and that's a really good sign." Meredith added.

Two days went by, and Beth was now awake and aware. Meredith had taken new scans to see if the virus was working. She immediately saw a change in the size of the tumor; it's smaller. Meredith rushed to find Derek to tell him.

"Derek!" Meredith smiled.

"Oh, someone's happy."

"You should be happy too." She handed him the new scans. "Look, it's shrinking. Derek it works. We did it!"

Derek grinned and gave Meredith a hug and kissed her. "I couldn't had done it without you."

"We couldn't had done it without each other."

"Come on, let's go tell them the good news."

I debated making this into multiple chapters, but I decided not to because I want to cover more things. So I hope you liked this chapter! Review, follow, and favorite!

**Also, I'm almost out of prewritten chapters so very soon I won't be updating as much unless I go on writing spree again, which I hopefully will.
