Not an Accident
Someone else in the car was stirring now and Harry could tell it was Dudley by the tone. The shouting had probably roused him.
"Dudley?" Harry called hoarsely.
"Dudley!" he shouted louder. Still, no cognitive response.
Hooking a foot outside the car, he half-scooted half-pushed himself slowly and painfully out the opening. As difficult as it had been to kick the door open, this was undeniably worse. He felt something jabbing him in his already achy side.
Harry jammed his free arm beneath himself and retrieved the offending item. His glasses. Or rather, what was left of them. The lenses were completely missing; a gnarled black wire was all that remained. He doubted even Hermione knew a spell powerful enough to repair this mishmash. Knowing it was hopeless, Harry stashed the wire into his sling with the pieces of his wand anyway. Just keep moving…
He twisted his body and spilled out of the car unceremoniously onto his knees. Ow, ow, ow, he chanted to himself with every painful breath. At least it was grass he'd landed on. They appeared to have crashed in some sort of park. And he was free. Free!
Quickly pushing himself up off the ground, Harry felt a ripple of nausea pass through him and vomited on the lawn. Shaking now, he lowered himself carefully back down. Just what I need, he thought disgustedly, to get sick all over everybody and everything. Things just can't go worse!
But in an instant they did. Infinitely worse.
Despite the already-present throb in his head, Harry felt an unmistakable staggering flame sear through his curse scar. It had been a good thing he was so close to ground; had he been standing, he would be sprawled out by now. As it was, he tried to make heads or tails of what he just sensed.
Voldemort…was…angry. Extremely angry...about something—furious in fact. Something involving him—Harry. Probably angry his Death Eaters haven't found me yet, he supplied mentally. This put a brand new sense of urgency on the situation. If Voldemort were looking for him, he'd have to get somewhere safe…quickly. He'd be an easy target, with no glasses, no wand, and a broken arm.
Harry stood up—more deliberately this time—and began squinting around in the darkness for his owl's cage. Turning in the direction of the car, he noticed something very odd indeed. Save for his door being open, he couldn't see a car at all. So the green-blue flash had been an Invisibility Charm. That explains why nobody came for rescue. Nobody could see them while they were in the car.
Harry could make out a little hillock further away from the opposite side of the car. It was the very incline where the Dursleys' car had come to rest at the bottom. Trying to focus his eyes on a glint he spotted in the distance, Harry skirted carefully around the area of car where he estimated the rear bumper was occupying.
Looking down, he lowered himself next to the glint. This was indeed Hedwig's cage. It was resting on its mangled wires, tipped over on one side. His pet owl was slumped over in the bottom, still and breathing very shallowly.
"Oh, Hedwig," Harry said roughly, "I'm so sorry…my faithful friend…"
Crouching down slowly, he opened and gingerly reached inside the cage. He lifted her gently and righted the cage with the toe of his shoe, and reverently set her in the bottom and shut the door.
"I promise, I'll get you help soon," he swore to her while slowly easing himself back up. Catching hold of the cage in his hand, he carried it over to the open car door and placed it inside.
Peering inside at the Dursleys, he couldn't see anything outwardly wrong with them, but that didn't mean anything, especially considering the fact he had no glasses. Dudley continued to make odd mumbling noises.
Despite the urgency to leave, Harry still found himself requiring a rest yet again. Each walk around was becoming more and more exhaustive as that horrible stitch in his side grew and it became increasingly harder to breathe.
He had figured out that ache was likely where the cursed seatbelt had restrained him. Oh well, as long as I'm still moving, he resigned to himself.
Now he needed to set about summoning immediate wizard assistance.
Even if Harry could open the boot, he knew he was in absolutely no shape to ride his Firebolt. It would be suicide. After all, he'd tried riding a broom with a broken arm once before with calamitous results.
More to the point, he needed to think of something that required minimum effort to accomplish due to his waning strength. This weakness of his was very disconcerting; he'd always been able to handle things before. Save for the dementors. However, he could now accomplish that with relative ease as well. What was wrong with him?
Harry leaned heavily against the invisible car. Never mind. What we need is transportation…for several people…fast...something glimmered across Harry's mind…
The Knight Bus? He nearly rejected the idea out of hand, it was so crazy. The Knight bus-turned ambulance? Absurd! Maniacal blind-as-a-bat Ernie behind the wheel…if the car crash hadn't killed the Dursleys, a ride in the Knight Bus was sure to. With a broken wand, he very likely couldn't summon the bus regardless. Unless…
Harry slid back down near ground and removed his mangled glasses and wand from the sling. Retrieving the phoenix feather buried in his pocket, he then placed it in the centre of one of the red-tinged halves of wand and lined it up with the other half. Good thing they still matched. Now for something to hold this mélange all together…
Gripping the wand handle in his left hand, he braced it between his index and middle fingers. Carefully, he secured one end of his glasses wire against the base of the wand with his thumb; with the other hand he spiralled the rest of the wire around up the tip as high as it would reach.
Harry looked dubiously at his woefully inadequate repair job. What a mess, he thought with distaste. After that, he pushed himself up the car fender again with great effort and positioned his feet. Here goes nothing, he thought. Closing his eyes, he buried his head against his shoulder and jutted out his wand hand.
Not a thing happened.
In a fit of frustration, he growled and hawked several large spit wads all over the dead wand. This WILL work, I HAVE to leave, Voldemort's on his way, he thought furiously whilst frantically smearing the saliva into the crack in his wand as best he could. And all of this hard effort is going to pay off right—
"NOW!" Harry shouted as he thrust his wand arm back into the air as high as it would go. A bolt of energy charged through him from toe to wand tip.
a large popping sound rent the air as the lurid purple Knight Bus
appeared and slowed to a stop not far from him.
