Not surprisingly, it was a scene of utter chaos which greeted Lily and Ethan as they arrived at the trauma site. A fireman strode over to brief them. He had dark hair flecked with grey, mostly covered by his helmet, and a moustache to match. He was of sturdy build, and carried himself with such confidence that people seemed to be waiting for his instructions before doing anything.

"No need to ask who you two are," he said, gesturing towards their emerald green, trauma doctor jumpsuits. "You've arrived just in time, I'll have to throw you into the thick of it." He pointed to where they could see Dixie and Jeff crouching by a gap in a wall. "Your lot from Holby are over there, we've got a casualty trapped over behind that wall, and her husband who won't leave without her. We don't know the extent of her injuries, but he has extensive injuries to his left leg and some pretty deep cuts. I'll leave you to do your job." Ethan thanked him and set off for Dixie and Jeff, closely followed by Lily.

Taking one look at the man, Lily put her foot down.

"Sir, you need to be in the ambulance, ready for transfer to hospital," she said firmly.

"But my wife -" he protested.

"I promise we will get her out as soon as we can. I'll make sure she gets the treatment she needs, I promise." Reluctantly, he allowed Ethan to treat his external injuries, and agreed to let Dixie and Jeff take him to the ambulance. Once they were out of earshot, Ethan rounded on Lily.

"You shouldn't be here," he said in exasperation. "Before Connie came in, you were seconds from telling me what was wrong. I know you Lily, at least I think I do, and I know something is wrong. You're not helping yourself by staying quiet!"

"Look at that gap in the wall Ethan. There's a woman in there who needs a doctor, now, and you're too tall to get to her. It has to be me! So please stop fussing, I need to get in there to get her out."
"Fine," Ethan eventually conceded. "If you start feeling any different to how you are now, you need to get out of there. And if they blow that whistle to say it's not safe, don't be a hero. Come out."

Lily looked into her boyfriend's face, smeared with dirt and layered with concern.

"You say that like I've never been on a trauma team before," she said gently. Ethan put his hand on Lily's cheek, knowing he had to admit defeat. "Trust me, please?" Ethan knew she could do nothing to dissuade her and gestured for her to crawl through the gap in the wall. Pushing her medical kit in after her, he watched he start to unpack things.

"I love you," he said quietly.

"I love you too. And I need you to radio the ED, we need a cardiothoracic surgeon ready to deal with severe crush injuries to her chest."

Lily started working on the woman's visible wounds and giving her pain relief, while trying to get her to regain some consciousness. She opened her eyes sluggishly.

"Hi there," Lily said. "My name's Dr Chao, can you tell me where you are?" The woman shook her head before Lily quickly stopped her. "Just try to keep your head as still as possible, I haven't ruled out any neck or spinal injuries yet. Can you tell me your name?"

"Annie," the woman said, before closing her eyes again.

"Ethan, are you there?" Lily called loudly.

"Of course, what can I do to help?"

"Okay, this is Annie, and we need -" Lily stopped to cry out in pain. She was in complete agony, pain radiating out from the bottom of her stomach.

"LILY!" Ethan shouted. "Lily, please talk to me, what's wrong?"

"I -" she gasped. "I can't – move."

"What happened, has something fallen on you?" Ethan was panicking, he knew he shouldn't have let Lily come out, he should have said something to Connie to stop her letting Lily onto the trauma team. Guilt was eating him up, tears welling in his eyes.

"No, nothing's – nothing's fallen." She stopped and Ethan could hear her crying softly. Lily wished she'd said something before, told anyone what was going on. Now there was nothing she could do, she'd put herself and her patient in real danger. Her sobs pulled Ethan back to being a doctor. He rubbed the tears roughly from his eyes, before listening intently to her weakening words.

"Ethan, it hurts!" she cried.

"What hurts? Please, Lily, stay with me!" He tried to piece together all the clues, trying desperately to work out what was wrong. No response came from Lily, he could only hear crying now, punctuated by gasps of pain. He wished he was in there instead of her.

Suddenly he heard a sound that made his blood run cold. A shrill whistle, the signal for all emergency staff to evacuate. Lily heard it too, and panicked, despite fighting to remain conscious.

"Ethan!" she screamed.

"I'm here," he said, as the fireman from earlier ran up to him.

"You need to get out of here, can't you hear the whistle?"

"My colleague, she needs help, I don't know what's wrong but she's barely conscious."
"Look, if you don't move sharpish, she won't be the only one needing medical attention. The roof's coming down mate." Ethan heard Lily's sobs intensify, as the fireman tried to pull him away.

"Lily, cover your head, I promise I'll come back for you!" he shouted as the fireman finally got his way and pulled Ethan from the building at a run.

Out on the street, they could hear more of the ceiling and part of the roof fall in. Ethan saw Dixie and Jeff's ambulance drive away: their patient's condition had obviously worsened considerably. He sat on the pavement with his head in his hands, his knees drawn up to his chest, not able to stop himself crying anymore.
