"So do you want to explain what's going on?" Cal pushed his brother.

"I told you already. I'm fine." Ethan didn't look up.

"If you don't tell me what's bothering you then I can't help."

"Who says I want your help?"

"Ethan." Cal sighed. "Please, don't shut me out. Talk to me."

"I'm tired." Ethan exhaled. "I can't do this anymore."

"We all make mistakes. Even me." Cal draped his arm around Ethan's shoulders.

"I'm talking about work. Not your private life." Ethan commented.

"Yeah, so am I."

"When have you ever made a mistake at work?" Ethan asked.

"Trust me. I've made plenty."

"Are you just saying that to make me feel better?" Ethan inquired.

"No. I have made many mistakes. Many mistakes that make me want to throw everything away."

"So why didn't you?"

"Because someone I know once told me 'I come back because I have no choice. Because you're my brother. And whatever that means I'll always come back for you. To protect you, to be there for you'."

Ethan smiled. He couldn't believe Cal had actually remembered his words. He turns to face him.

"And who told you that?" Ethan grinned.

"One of the best doctors I know." Cal smiled back.

Taking of his glasses, Ethan began to fiddle with them.

"What's wrong?" Cal asked.

"Look, I'm grateful you're trying but, I've made up my mind. I can't stay here anymore, Cal." Ethan told him truthfully.

"So, you're really doing this? You're really leaving?"

Ethan nodded.

"But, what am I supposed to do without you?" Cal whispered. "How am I supposed to cope without my little brother?"

"You'll manage. You always do."

"No, that's not true."

Ethan faced his brother. Cal saw tears in his eyes.

"I'm sorry, Cal."

So this was it. Ethan was quitting a job he loved doing. He was leaving behind those who cared about him. Cal couldn't watch his brother leave without telling him the truth about their adoption. He knew the only way of making Ethan stay was to tell him. It sounded like a selfish reason for doing it but, he couldn't let his brother leave and then find out Ethan had Huntington's. He wouldn't let his brother go through it alone.

"Ethan, before you go. There's something I need to tell you."

"Uh, okay. But, do you mind if we talk later. We both should be getting back to work."

"Uh, yeah sure. We'll take later then." Cal managed to reply.

Ethan replaced his glasses and headed back out to cubicles. Charlie passed by the staff room and saw Cal sitting on the sofa.

"Knock, knock." Charlie said.

"Hiya, Charlie." Cal answered, looking up.

"Everything okay between you two?" Charlie asked.

"Between me and Ethan? Yeah, of course. Why shouldn't it be?" Cal wondered, standing back up.

"I couldn't help but, notice Ethan was upset. I just wanted to know is there anything I can do to help?"

"I suppose you've heard then?"

"Heard what?"

"Ethan's decided to quit."

"He did what?"

"Yeah. He's quit and is planning to move to Australia."

Hearing Ethan was quitting came as a shock to Charlie, but to hear he was moving to Australia, Charlie couldn't take it in.

"You're being serious, aren't you?"

Cal nodded his head in response.

"And you still haven't told him?"

"No. But, I plan to today. It's the only way I can make him stay."

Charlie looks at him.

"I know that shouldn't be the only reason to tell him. But, I can't lose him, Charlie. What if Ethan's inherited the gene? I can't let him go through it alone."

"You know by telling him the truth it could push him further. It could make actually want to leave Holby."

"I can't just stand back and watch him throw everything away. Anyway, he'll understand why I kept it from him."

"Are you sure about that?"

"Of course. He'll know the only reason why I did what I did was because I love him."

Both he and Charlie went back to work. The doors to the ED swung open. Dixie and Iain rolled in with a patient. Ethan went over with Rita and Robyn. Taking over from the two paramedics Ethan began doing the primary observations. If this was going to be his last he would make sure no one died on his watch.

"Right, can I get full FBCs, U & E, LFTs and a blood gas. Can we also call CT and x-ray." Ethan ordered. "Hi, there, My name is Dr. Hardy and I'll be your doctor. Don't worry you're in safe hands."

With the patient's neck stabilized Ethan was busy looking at the CT scan results. He was about to inform the patient on what was happening when the machines started to go erratic.

"Ethan, breathing is wheezy and SATs are dropping." Rita informed him.

Rushing over Ethan placed his stethoscope in his ear. Breathing sounded laboured.

"Could you open your mouth for me?" Ethan asked, shining a torch into the patient's throat. "Yes, the throat is closing in up. Right, we need to lay him down before he arrests."

As soon as the patient was laid down Ethan lost on output. Rita stepped up and began chest compressions while Ethan bagged and masked him. 30 minutes later and there was still no output. The patient had gone into VF so Ethan took over.

"Please don't die on me." Ethan said to himself.

After a second round of chest compressions and a shock to the heart Ethan continued on doing CPR. Rita could see Ethan wouldn't stop.

"Ethan," Rita said. "Do you want me to take over?"

"No, it's fine. Give him another 5 mg of adrenaline."

Ethan carried on. There was still no pulse. Rita could see there was no chance of them restarting his heart. Rita placed her hand on top of Ethan's.

"Ethan, stop."

"No. I'm not giving up."

"Ethan, we've done everything we can. Both his pupils are blown and he's been in in a systole for 45 minutes."

Ethan wasn't listening to her. He carried on pumping down on his patient's chest. Rita took Robyn to one side away from Ethan.

"Go and get Zoe for me." Rita whispered to her.

Minutes later Robyn re-entered RESUS with Zoe following behind. She saw the monitor and saw Ethan. Walking up to him she stood in front of him.

"You have to stop, Ethan."

Ethan continued on with the compressions.

"Dr. Hardy." She tried using his professional name. "He's had no output. You must stop what you're doing."

Ethan stopped. He took of the gloves threw them on the floor and stormed out of the room pushing the doors as he did so.

"Time of death 14:55." Zoe announced.
