6 hours earlier...

Cal stumbled across the ambulance bays. His eyes and ears still adjusting to the chaos in front of him. He became aware of a bundle of clothes on the ground in front of him and frowned as he tried to understand why someone would have left them in his path. He shook his head in an attempt the fog inside and the bundle took on a form, the garments a familiar shade, a uniform. He was next to the shape now. Christ it's a body. He pulled at the collar of a jacket, an arm. Revealing a dark head of hair, a bloodied face he recoiled as he recognised his colleague and friend.

"Cal, have you got this?" the voice of the senior nurse broke through Cal's thoughts. "Cal?" Urgent but calm.

"Charlie… Shit… I can't… It's… I think this is my fault" the doctor faltered.

Moments earlier Cal and his brother has been knocked off their feet by the impact. His younger sibling, ever the cautious one, had remained motionless a fraction longer than Cal was comfortable with. He'd prayed to a god he didn't believe in - please no anyone but Ethan - and was now starting to think that his negotiation might have been a touch hasty.

"This isn't your fault Cal. He was in the helicopter. God knows how but he's got himself out. You need to focus Cal. He needs you. I've got a pulse. It's weak but it's a pulse. We're looking at potential serious head trauma, crush injuries. Max! Trolley over here please quick as you can. It's Iain"

Rushing through into Resus they were met by Elle, the composure in her face faltering briefly as she recognised the battered form of the first member of team to make her feel welcome on a very stressful first day. Boy did that seem a long time ago now. The consultant instinctively reached for Iain's hand as Charlie recounted what little stats they had on their patient.

Cal was vaguely aware of Elle dismissing Charlie, telling him to get back out there, organise triaging the injured, bring some much needed calm and order to the situation. He heard Elle tell him he was to assist her. He found himself in Resus alongside Iain though he had no recollection of how he got there.

Elle was starting a primary survey. Familiar terms washed over him. Robyn already setting about the tasks she'd been allocated, blades making easy work of layers of paramedic green as she exposed an arm for drawing blood.

"Cal...? Doctor Knight!" Elle's voice brought him back to his senses once more. "We're going to need a head-to-pelvis CT but I'm concerned about his respiratory effort. Can you have a listen please?"

Within an instant Cal had his stethoscope plugged into his ears, leaning closer to his colleague as he moved the instrument over his chest. Grimacing he straightened up informing the senior doctor they were going to have to perform a chest drain for a right side pneumothorax. As he readied the equipment next to the patient Iain started to groan. Cal leant into him once more.

"Iain mate it's Cal. You're in Resus. You were in a… the helicopter came down mate. God knows how you got out. Pig stubborn with a thick skull probably…" Iain's eyes were open now. Green flecked with orange staring in the doctor's direction. Staring not at him but through him. Cal flinched as Iain grabbed at his hand.

"Why she's not coming back?" He rasped urgently. Confusion flickered across Cal's face.

"Where is she? She said she was only going to the shops. Where is she Hannah?" Iain's eyes were desperately searching Cal's face now.

"Hanna-?" he started but the conversation had to wait as Iain started straining to get up.

"No, no, no you don't Iain. You've got a collapsed lung and god knows what else. Don't fight me you idiot!" Cal was practically shouting while he tried to restrain the man and suddenly Iain started to gulp for breath. "Elle can you take over the procedure? I think it's best if I hold him down"

Robyn watched the events unfold on autopilot. So far she'd managed to block from her mind that the man she was treating was a colleague and friend. It was crucial Iain stayed still for this and she watched Elle and Cal struggle feeling powerless to help. A memory of her former boss flashed through her mind, not surprisingly given who the patient was, but it was exactly what was needed to snap the young nurse back into action. She moved to the top of Iain's bed, to where Cal was gripping his right arm to keep it above his head. Instinctively she slipped her hand into Iain's, squeezing reassurance.

"Iain it's ok. I'm here" she whispered softly, her thumb rubbing circles on the back of Iain's hand

"Hannah?"

"Iain it's ok. You're with the doctors. You just need to stay very still. They want to help you. I'm not going anywhere. You're okay"

Elle smiled up at Robyn encouragingly. It was working, Iain's eyes seemed to glaze over as his body visibly relaxed. His heaving chest also calming as the consultant successfully completed her work. Robyn glanced up at the monitor, her eyes widening seconds before the shrill electronic bleeps alerted the rest of the room what she'd observed. She reacted first.

"He's in VF"

"Cal start compressions"

It was only a matter of seconds but felt like forever to the blonde doctor. His own chest heaving with the physical effort of first one cycle. No pulse. A second cycle.

"Iain mate. Come on. Don't do this"

Nothing. Catching his breath while the defib whirred up to the correct voltage.

"Shocking"

Iain's helpless body thrown up from the bed with the charge. A deafening silence. Cal didn't hear it at first but the slow rhythmic beep started to infiltrate his thoughts only after he acknowledged the relieved smiles spreading on the faces of his female colleagues.

"Back in sinus rhythm"

Iain's eyes opened and he stared around his surroundings once more. He looked terrified, like a little boy lost Robyn thought as she reached for his hand once more.

"Why is she not here? I've got to find her" his voice was a cracked whisper but the agitation was obvious. Eyes darting, shoulders tense. "I've got to make sure she's okay"

"Hannah?" Robyn offered helpfully.

Iain looked at her with what looked like disgust and snatched his hand away.

"Hannah?" Iain echoed. "That has got nothing to do with you!" he hissed "Get off me I need to find her!"

"Iain mate you've got to calm down. Let us treat you. You've been in a serious accident we need to get you to CT!" Cal was physically restraining him once more as he spoke.

"This is ridiculous" Elle spoke calmly. "They won't take him like this. I feel we've no option but to sedate him. His heart has already failed once. I won't have it happen on my watch. Doctor Knight are you in agreement?"

Cal tightened his grip on Iain's arms and nodded reluctantly. They had no choice.
