The next morning Cal's mind was all over the place. He had spent the whole night tossing and turning, worried about what Ethan had said. Every couple of minutes Cal would lie very still in case he heard the door to his brother's room open. All night he kept imagining all sorts of terrible scenarios of finding his brother unconscious or worse, dead. When he got up this morning, Cal even went into his brother's bedroom to check if he was still breathing. Then before Cal left to start his shift, he checked on Ethan again. Now at work his mind was still unfocused that it was affecting his work both Charlie and Elle noticed.

"Cal?" Charlie repeated for the third time.

Cal broke away from his thoughts when he heard Charlie call his name.

"Uh, yeah. Sorry, I was miles away."

"I saw." Charlie answered. "The patient in cubicle 4."

"Yeah, what about him?" Cal asked.

"Is he good to be discharged?" Elle inquired.

"Not yet. He's still complaining of chest pains and shortness of breath. I would like to keep him in for observation." Cal replied.

"Okay, but other than that he's okay?" Elle asked, but Cal was once again not listening.

"Cal?" Elle said.

"Yeah, other than those symptoms he's okay."

Elle and Charlie were about to leave him to treating his patient when they stopped.

"Are you sure everything's okay, Cal?" Charlie asked as he placed a hand on his shoulder.

"Yeah, I'm fine." Came his reply.

Charlie looked at Elle. Both seemed to be not convinced by his answer. So indicating for Cal to follow them. The three of them headed into Elle's office. Elle sat down in front of Cal while Charlie stood beside her.

"Cal, what's going on?" Elle wondered.

"It's nothing." Cal responded, avoiding eye contact.

"It's not nothing." Charlie added. "Are you ill?"

Cal shook his head.

"Then what is it?"

Cal remained silent for a few minutes longer. He debated about whether he should tell them about what Ethan had said to him. But, then for a minute he thought it was better if he didn't. After all, it was none of their business. It was between him and Ethan. But, then again they were his colleagues and friends. They would do everything they could to support them. Finally, Cal decided to tell them what was going on.

"It's Ethan."

"Ethan?" Elle inquired. "Is he ill?"

"Not exactly." Cal commented.

"What do you mean 'not exactly'?"

"It's just something he said to me last night."

"What did he say?"

Cal hesitated.

"He told me that he wished he had died during the helicopter crash."

Elle and Charlie looked at him with shock written all over their faces. They were stunned at Cal's admission.

"Ethan said that?" Charlie said.

Cal nodded.

"Why would he say that? Elle questioned.

"It's kind of complicated." Cal responded.

"Complicated how?"

Cal didn't answer. He didn't want to tell Elle or Charlie about Ethan's diagnosis, but at the same time he didn't know what to do and he needed help.

"Ethan has Huntington's." Cal announced.

"What?" Charlie asked shocked.

"Yeah, he's got the gene, Charlie."

"Oh, Cal." Charlie sighed. "I'm sorry."

"It's not your fault." Cal said.

"And do you think Ethan meant what he said?"

Cal shrugged.

"I don't know. I mean I hope he didn't mean what he said. I also know him and know he wouldn't something that rash. But, then again ever since his diagnosis and the helicopter crash he's been different. I don't know what to do."

"For now, all you can do is be there for him. You'll also have our support if you need it." Charlie told him.

Cal nodded and left the office. Elle turned to Charlie.

"I had no idea." Elle admitted.

"Neither did I." Charlie commented.

Cal decided to take his break. While on his break he decided to check up on Ethan and so dialed his number. But, he didn't receive an answer. Worried that something must have happened to him he tries again. On reception, Noel could see Cal was worried about something.

"You alright, mate?" Noel asked once Cal was off the phone.

"I'm trying to get hold of Ethan. But, he's not answering." Cal explained to him.

"Ethan's in cubicles." Noel told him.

Noel's answer worried him a bit. Even though he knew Noel meant he was working in cubicles Cal also thought he meant Ethan had been admitted to cubicles. So just to make sure he asked Noel if he was treating a patient. To which, Noel clarified that he was treating a patient. Knowing that Ethan was working Cal could now get back to his own patients, even though he was still worried about his brother's state of mind. In cubicle 6 Ethan and Robyn were treating 10-year-old Matthew, who had fallen off a climbing frame. He came in an ambulance with his older brother when Matthew was knocked out unconscious and couldn't move his foot. When he arrived at the ED, Ethan had ordered the usual FBCs, U&Es as well as a CT scan and x-ray. The CT scan was clear but, Ethan was going to keep his patient in for 24 hours just to make sure. As for the x-ray, it revealed that Matthew had fractured his ankle and would need a plaster cast put on it. Ethan was writing up his notes when all of a sudden his whole hand jerked. Ethan swore under his breath as he noticed his handwriting had become illegible. He tried to amend his writing when once again his hand made an uncontrollable movement.

"Ethan, are you okay? Robyn asked when he heard Ethan mutter to himself.

"Yes, I'm fine." Ethan replied, pushing his glasses up on his nose.

"I'm just going to fill the rest of this paperwork out and then I'll come back to put the ankle in plaster." Ethan told Matthew.

Ethan was almost out of the cubicle when he felt his leg gave way and the clipboard he was holding clattered to the floor. Groaning to himself he picked up the items off the floor. He placed the clipboard on top of the counter before heading towards the staffroom and slamming the door behind him. Robyn noticed Ethan's odd behaviour. He was acting strange, not like his normal self and it was worrying Robyn so after checking Matthew's vital signs she went off to find Cal. Maybe he knew what was bothering Ethan? Robyn found him treating a patient in HDU.

"Um, Cal?" Robyn interrupted, hesitantly.

"Not now, Robyn." Cal replied.

"But..."

"I said not now. I'm with a patient at the moment."

Sensing this wasn't a good time and Ethan seemed to be alright on his own Robyn left HDU. On her way back to reception she spotted Max.

"Max, could you do me a favour?"

"Only if we can have pizza tonight."

"Fine."

"Yes! Okay, so what's the favour?"

"Can you check on Ethan for me?"

"Why?"

"He was acting a bit strange earlier on. I just want to make sure he's alright."

"Okie dokie, and don't forget pizza." He called out as he walked away.

Max had reached the staff room and was about to open the door when he looked through the glass.
