It took awhile for the news to sink in. Cal could see Ethan was trying to remain calm, but it didn't last long. Ethan soon snapped.

"Why did she give us up then? Surely, she should have told us, surely mum would have told us?"

"I'm not excusing her what she did, but she wanted us to have the perfect childhood. As for why mum didn't tell us, she didn't know."

"Surely, she must have known."

"Emilie, our real mum, didn't tell her. In a way she wanted to protect us. So did mum."

"Protect us? We had the right to know. There is still a 50/50 chance either one could have inherited the disease. Did she even think about that?"

"Of course, she thought about that. But, there was also a chance we wouldn't inherit it. That's why she gave us up for adoption. So we could grow up without the fear of wondering if and when it was going to happen."

"And what if one of us does have it? What do we do then? Are we supposed to be grateful for her not telling us?"

"I know what she's done is unforgivable, but at least try to understand where she's coming from, Eth."

"Understand? Understand what? She kept an important piece of information from us."

"She was trying to protect us."

"Like you were doing when you decided to not tell me?"

"Yes."

"Why? She should have told us. You should have told me. You're both as bad as each other. Only thinking about yourselves."

"Ethan, I know you're angry. But, that's not true. Yes, it some ways we are similar. However, the only thing we have in common is the fact we both wanted to protect our family. She only wanted to protect us because she loved us."

"And what about you, Cal? You only make decisions that affect you. You never think about anyone else apart from yourself."

"You know that's not true. I only did what I did because I care about you."

"Really? Since when have you ever thought about me?"

Ethan's words cut through Cal's heart like a knife. Yes, there had been times in the past were Cal had made stupid mistakes, mistakes he wished he'd never made, but he would never intentionally hurt Ethan. Surely, Ethan knew that. Or so Cal had thought. But, hearing those words come out of Ethan's mouth Cal realised Ethan never knew how much he cared about him. Then again, Ethan never had the reason to know that for Cal had never been the one to affirm his feelings for his brother. He guessed at this point in time it would be a good time to say how much Ethan meant to him. For if he didn't, Cal had a dreadful feeling he could lose him and that was something he didn't want to happen.

"Of course, I care about you. I've always cared about you. You must know that." Cal looked desperately at him.

"You've never showed me." Ethan replied frankly.

Cal grabbed Ethan's face in between his hands and looked straight at him.

"I know I haven't exactly been good at expressing my feelings, but I love you." Cal told him firmly. "You're my little brother, Ethan. I may not always show it, but I'll always love you."

Ethan shook his head. They were just words. And after everything that had happened he didn't know if he believed Cal. Pulling away from Cal's grip the heart monitor soon began to speed up and Ethan's breathing began to become strained. He gripped the sheets as he became tachycardic. Cal slid out of the bed and grabbed the mask switching the oxygen on as he placed it over Ethan's nose and mouth.

"Take deep breaths for me, Eth." Cal said rubbing his back.

Ethan tried to take deep breaths, but his breathing was becoming worse and his vitals were increasing.

"Cal," Ethan winced. "Chest hurts."

Ethan grabbed onto his chest and collapsed onto the bed scrunched up in pain. Cal raced out of the room towards reception. Half way down the stairs he spotted Charlie and Zoe.

"Can I get some help up here?" Cal called out.

"Cal?" Zoe inquired turning around. "What happened?"

Cal didn't respond. Charlie and Zoe followed him up the stairs. They saw him go into the room where Ethan was. Upon entering they saw why Cal was so worried. Ethan was lying in bed holding tightly onto his chest as the monitor was beeping at a very fast pace. Zoe walked over to Ethan's right side of the bed taking her stethoscope and placing it on his chest. After a few minutes of checking his breathing, Zoe replaced her stethoscope back around her neck.

"Can you give me an update on his vitals?"

"Pulse is 170. BP is 120/70." Charlie fread off the screen.

"Cal, can you tell me exactly what happened?' Zoe asked.

"We were talking and then he said his chest hurt."

Soon the monitor was going erratic. And Ethan was becoming agitated.

"Right, he's going into SVT." Zoe called out. "Let's roll him to RESUS before he loses an output."

The three of them rolled Ethan to RESUS. Cal stepped aside as he watched Zoe and Charlie work quickly to get Ethan's vitals back to normal. While Charlie was hooking him up to an IV line of saline, Ethan began to thrash about. He tried to pull the line out of his arms. Zoe tried to placate him but holding him down by the shoulders. He struggled against her grip and kicked his legs tangling himself up in the sheets. Cal could see Ethan wasn't calming down so he walked over to the bed. He knelt down so Ethan could see him.

"Ethan, you need to calm down." He said stroking Ethan's hair. "We're just trying to help you."

" It hurts. I'm scared." Ethan whimpered as the pain in his chest got worse.

"Yeah, I know. But, that's why we're trying to help you. So you can get better."

Cal saw Ethan's hand go limp in his. He tried squeeze it to get a response.

"Ethan? Ethan, can you hear me?" Cal said panically.

"He's lost his output." Zoe said. "Charlie, bag and mask him. I'll start chest compressions."

Cal staggered back as he watch Zoe press down on his brother's chest. After 30 minutes Zoe stopped and placed two fingers against Ethan's neck. Cal held his breath as he waited for Zoe to announce Ethan had a pulse.
