Stone dust hung in the air like a fog. All along the abandoned muggle streets were signs of destruction, brick and mortar crumbled like children's blocks and concrete bowed in like a half dried clay pot. The air smelled sour and bright, the dust pricking on the back of his throat dryer than desert sand. There was a boom in the distance, the street shaking faintly underfoot followed by a tense unnatural silence broken a minute later by the sound of bricks cascading across asphalt as a wall somewhere collapsed.

Draco stayed close behind the auror's, his hand trembling faintly with adrenaline. Row was bright, vibrating with excitement. Her partner was an auror that was a permanent glower given human form, he hadn't looked at Draco even once.

Row stopped at the edge of the next building, casting, "Homenum revelio," for the third time since they had slipped out from behind the bus. "Got it!" She hissed, bouncing on her toes before darting forward to a shop across the street.

Draco and Glower hurried after her into the building. The door had been blown inward, shelves had been knocked over, food scattered across the floor and underfoot and at the end of the destruction, an unconscious auror.

Row waved at Draco impatiently to hurry up and when it wasn't fast enough, Glower grabbed Draco by the front of his robes and pulled him forward, letting go only to roughly shove him the rest of the way.

Draco shot Glower a glower of his own as he skidded through bags of crisps before kneeling next to the man and casting his diagnostics. It showed no wounds internal or external, but quite likely a concussion. Draco opened a pain potion before reviving the man with a rennervate.

"Hurry up!" Row said impatiently, wading through the debris back to the front of the shop and carefully peering around the side.

Draco didn't bother dignifying that with an answer. He told the auror, "You hit your head. This will help," he held out the potion, "It's a pain-away potion," he clarified impatiently at the man's hesitation.

The man took the potion and Draco pulled him to his feet. Glower had joined Row at the door. Draco took the man to join them.

"Head injuries are dangerous. You need to return to the overturned bus where Weasley is and report to the healers as soon they arrive," He told the man, and because aurors were in his experience stubborn idiots who would try and shrug off any injury no matter how life-threatening, he added coldly, "This could kill you. If you do not report to the healers I will track you down and drag you there personally, understood?"

The auror nodded nervously and after some very quick words with Glower, the injured auror was hidden under a disillusionment spell and headed towards the triage area.

Glower shifted over to look past Row's shoulder, "Come on, let's-"

There was a distant boom that made the shop shudder, the ceiling above them raining dust and creaking ominously. Draco ducked behind an empty shelf. He pulled himself up just in time to see Row running out of the shop towards the explosion.

Glower yelled at her to come back, took one look at Draco and then promptly left, chasing after Row and leaving Draco alone in the rubble.

Draco swore under his breath, trying desperately not to panic. He knew he should go back to the bus but if he did there was no way Weasley was going to send out another team and Harry was still out there. He couldn't leave him.

Draco uncorked a calming draught and took a rather large swallow. He edged just far enough out to cast homenum revelio. He could see the faintest outlines of the fight a few blocks away, it looked like both sides had taken cover and were trying to wait the other out. Row had led them a lot closer to the fighting than Draco had realized but considering all he knew about Row, who was obviously lacking in even the barest amount of common sense to be a Ravenclaw, he was not surprised.

Draco cast a disillusionment over himself before slipping out of the shop and carefully making his way further up the street, parallel to the fighting, searching as he went. He reached the barrier and considered giving up, heading back but remembered that Weasley had said Potter wouldn't be visible to the spell.

Knowing it was a bloody stupid thing to do, he nonetheless moved another block closer. He took care to study areas where it was apparent fighting had occurred, glancing over rubble-strewn streets, down scorched alleyways and damaged shops. Everything was so unnaturally silent that every shifting stone under Draco's feet sounded like an avalanche. He edged past a broken wall, stepping into a shop that had almost been entirely gutted by a blasting spell. He raised his wand to cast another revealing spell and paused at the faint sound of- a bellows? A broken bellows?

A thunderous crash startled Draco backwards and he tripped, falling over something too warm and soft and too human. He looked down and saw his legs laying over something invisible and a standard issue dragon-hide boot. Draco quickly pushed the debris out of the way so he could kneel beside the figure, pulling off the fine silvery cloak covering them.

It was Harry, his normally tan skin ashen and panting in short laboured breaths, sweat beading on his brow. Draco reached up, touching his cheek and found it clammy and cool.

"Get a grip," Draco muttered to himself, tightening his grip on his trembling wand and mentally commanding himself to stillness. He cast every diagnostic spell he knew, his chest growing tight with every red aura, jagged line and unsteady image. Internal bleeding into the chest cavity, through it was slow. Caused by a badly broken rib that had punctured the lining of Harry's lung, the air from his lung was filling the lining and slowly collapsing it and the slow bleed wasn't helping matters.

He felt a surge of panic and took every nerve he had left in his body the stay exactly as he was, as still as he could, forcing his whirling mind to think and be logical. Emotions wouldn't help him here, the war had shown him that. Draco quickly put up a shield, a repelling charm, hopefully mild enough not to be noticed, and cast an illusion over them that would make them look like a collapsed pile of brick. He pulled the half used calming draught from his vest pocket and finished it, clinging to the false sense of ease it provided.

Draco pressed his wand to Harry's skin, " Rennervate ," he murmured.

Harry blinked, his mouth falling open as he tried to gasp and fell to coughing, panic creasing his expression, blood flecking over his pale lips.

Draco sat up, leaning over Harry, shards of stone and wood digging into his palm as he cupped Harry's cheek, "Harry! Harry listen to me-"

Harry's green eyes focused on him.

"Slow- You have to take short, shallow breaths." Draco ordered, his voice surprisingly steady, "Your lung is collapsing, if you keep trying to breathe deeply or cough you're only going to collapse it faster. Short, shallow breaths. I know it's not comfortable but you have to do it, do you understand?"

Harry nodded slightly, his brow furrowing as he fought to bring his breathing under control and down to a short uncomfortable pace.

"I can't do everything you need," Draco said, biting his lip briefly, "but I can stabilise you until someone comes."

Harry nodded again, looking at Draco with an expression of absolute trust that made his chest ache.

Draco swallowed hard, leaning back, "Before I can stop your internal bleeding I have to fix the bone that caused it. I normally immobilize the afflicted area so I can heal unimpeded, I can't do that with you because you're breathing is already so limited."

Draco picked up his wand in his other hand, "It's going to hurt and you can't move. If you move, the bone might shift and heal improperly and will have the be rebroken and reset." Draco hesitated, his analytical tone falling away, "Can you- Harry? I need you to do this."

Harry nodded.

Draco gently traced the ridges of Harry's ribs until he reached the damaged ones. He cast a quick little charm that put things back where they belong, keeping it small and focused and felt when the rib shunted sharply back into place.

Harry clenched his jaw, the tendons on his neck standing out as he fought to stay still.

Draco took out a skelegrow and removed the seal. He felt himself hesitate and knew it was stupid, it might hurt him but it would help more in the long run. He held the vial to Harry's lips, "Ready?" he asked.

Harry met his eyes, "Dra-co," the debris shifted as he lifted a shaking hand, reaching out imploringly.

Draco took it without thinking, squeezing Harry's hand tightly.

Harry lifted his head slightly, swallowing the contents of the small vial with a grimace and a suppressed cough, letting his head fall back onto the ground. His breathing picked up, his shaking fingers squeezed Draco's hand so hard it hurt.

Draco tossed the vial aside so he could hold Harry's hand with both of his, "You can do this. If anyone can it's you, Harry," Draco said quietly.

Harry pried his eyes open, shooting Draco a look that quite clearly thought he was full of shit.

Draco could practically hear the teasing tone in his head. He managed a weak smile, "You're the most stubborn fuck I've ever met, that's why."

Harry's teeth flashed in a brief smile that was quickly lost under a grimace of pain.

It seemed like a thousand years passed before Harry's breathing began to ease and the forehead smoothed. Draco let go of his hand to recast his diagnostics, running his hands over Harry's side, tracing the previously broken rib and letting out a little sigh of relief.

"Good. It healed well," he said aloud.

He needed to heal the internal puncture next. He hadn't been taught many internal healing spells, they were delicate little things and the wrong spell in the wrong place could just as easily fuse the patient's liver to their kidney if the caster didn't know what they were doing. There was one very basic wound healing spell that had some effect internally as well as externally if he could get it to take hold and the wound was small enough.

"I'm going to try and heal the puncture in your lung," Draco said.

"Dra-co," Harry said faintly, his breathing still a shaky wheeze. His hand grabbed the fabric of Draco's robe, twisting it tightly in his hand. "Dra-co, nee-d to te- to tell-"

Draco put his hand on Harry's forearm and smiled faintly, "Tell me when you're better, Potter. Even if I can't heal your lung, you'd still have probably an hour before you'd go into shock or hypoxia and even then I could put you into stasis."

Harry relaxed slightly, his grip loosening, "Pro-mise?"

Draco nodded, "Yes, now shut up so I can work."

Harry grinned faintly.

It took three tries to get the healing spell to work but once it did the internal bleeding stopped and Harry's lung function stabilised. His lung was still partially collapsed and there was blood where it didn't belong but he was no longer in immediate danger.

Draco was giving Harry a blood replenishing potion when the sky filled with streams of green sparks.

Harry coughed down the rest of the potion and nodded to them, "We-re safe now."

Draco wiped the potion from the corner of Harry's mouth, letting his hand linger on his cheek, and pointed his wand at the sky sending up red sparks.
