"Lofty, what is it?" Cal asked as he and Iain walked through the door.

Lofty hesitated at the question. Both Iain and Cal saw the hesitation and knew something had happened.

"Lofty!" Cal raised his voice.

"Ethan's missing." Was Lofty replied.

Cal's stomach tightened.

"How is he missing?"

"I only left the cubicle for a few seconds while I sorted out his paperwork and by the time I returned his bed was empty."

"Might he be in the toilets?" Iain wondered.

"No, we've checked. He's nowhere in the hospital."

"Okay, so who's we?" Cal asked.

"Me, Charlie, Zoe, Robyn and Max." Lofty told them.

"Well, he can't have gone far." Iain stated.

Just then they were interrupted by a phone call. All three took out their phones to check if it was one of them. It was Lofty.

"It's Max." Lofty said, placing the phone to his ear.

Iain and Cal saw Lofty's expression change. Whatever Max had told him it didn't look good. Lofty ended the call and motioned the other two to follow him out towards the front of the hospital. Arriving at the entrance the three of them witnessed a huge crowd beginning to gather.

"What's going on?" Cal asked as he sprinted over to Charlie, Zoe and Max.

"Cal." Zoe sighed. "Now, I don't want you to panic. You need to stay calm for me. Ethan's been taken hostage."

"Well, what are you standing out here for?" Cal asked.

"We're waiting for an all clear."

But, Cal wasn't having any of it. He wasn't going to wait outside while some maniac was holding his brother hostage. For all he knew Ethan could be hurt or even dead. Hastily, Cal shook the thought out of his head. No, Ethan wasn't dead. If he was, he would have known. Ignoring Zoe's protests and pushing past security Cal burst through the hospital doors. Once inside he stopped to listen. He could hear faint whispers of voices coming from the exit leading up to the roof. He followed the voices hoping to recognise one of them as Ethan's. Before, he could reach the door he felt a sharp pain in his head as he fell to the floor and unconsciousness overtook him. When Cal regained consciousness his head felt sore. He blinked a couple of times to adjust to the bright lights. Just as he became fully aware of where he was he heard the sound of high heels coming towards him from the other direction.

"Cal?" Zoe asked as she rushed over. "Are you okay?"

"Uh, yeah I think so." Cal replied.

"What happened?" Zoe asked him as she helped him up.

"I don't really know. I think someone must have hit from behind."

Zoe went to check Cal's head for any signs of injury but, he shrugged her off.

"Look, Zoe. I'm fine. But, I think I know where Ethan is."

Zoe looked at him waiting for him to continue.

"Before I blacked out I heard voices coming from the entrance leading to the roof. I followed but, that was when I got knocked out."

Zoe and Cal were about to head up the stairs towards the roof when Iain ran in. He motioned for them to follow him back outside. Hurrying after him Zoe and Cal went back outside. Once they reached the others they both looked in the direction of where everyone else was looking. Up on the roof top very close to the edge they could see two figures. One of them they could clearly recognise as Ethan. While the other one was behind him and holding him close to the edge. Cal ran towards his brother still looking up. Now his heart was racing. He needed to get up there before Ethan got hurt.

"Is that who I think it is?" Robyn asked Iain as she too looked up at the scene that was escalating.

"Yeah, that's Bonnie." Iain answered her question.

"What is she doing back here?" Robyn wondered. "I thought she would have known better than to come back here after what she did."

"I guess she wanted to make sure she finished her last job."

A scream broke through the crowd. Everyone watched in horror as a body fell from the roof. The was a dreaded thud as the body hit the ground. Everyone looked up. Bonnie was gone. Cal gulped before running over towards the body. He felt his stomach churn as he saw the sight of Ethan's battered body lying on the concrete. His body was all twisted and a pool of blood was forming around his limp body. Cal was brought out of his thoughts when he heard the voices of Zoe and Connie rolling out instructions. He watched on as he saw Lofty thumping down on his brother's chest trying to restart his heart. The team rolled into the ED and straight into RESUS with Cal following behind. As the others took Ethan through the doubles doors, Cal hesitated. He couldn't lose Ethan. Not like this, not when they had so much they needed to talk about. He shook himself out his trance and burst through the doors.

"Cal, you can't be in here." Connie ordered as she took control of the situation.

"No, I want to treat him. Let me treat him." Cal said as he walked towards the bed.

"You know the rules, Dr. Knight." Connie told him.

"Please, Connie." Cal begged as tears began to blur his vision.

"Do not make me call security." Connie warned.

Reluctantly, Cal let Charlie lead him out of the room and to the staffroom where they waited in dreaded silence for some news.

"I can't loose him, Charlie. Not now. We need to talk."

"And you'll have time for that later."

"Well, what if I don't?"

"He's in the best capable hands, Cal and you know that."

Cal looked at Charlie. Why was he trying to keep things positive? He knew the chance of surviving a fall from that height was small.

"Please, Charlie. Spare me the talk of having hope. You saw how high he fell."

"Since when did you lose any hope of your brother surviving?" Charlie asked in shock.

He could't believe Cal was thinking the worst. He actually thought Ethan was going to die.

"I'm just being realistic that's all." Cal answered.

The door in the staffroom opened to reveal Lofty. Cal stood up.

"How is he?" Cal asked, his throat dry.

"Connie would like to see you in her office."
