The whole ride to the hospital, Jack was trying to think of anything but what had happened to him.
He was relieved that Chief Pitchiner hadn't pushed past the building back at the house, but he knew it wouldn't last. He figured they'd have to ask him what happened eventually for their report.
But... Jack didn't think he could handle describing what he'd been forced to see or endure. He didn't want to relive watching the others die. He didn't want to remember how it felt being tied up at the wrists, gagged, blindfolded, and dumped out in the woods to hold his own in his vulnerable state.

He wanted to forget any of this ever happened.

Jamie's hands tightly around his the entire ride to the hospital kept him calm enough, but once they reached the hospital and the boys were separated - Jack taken in by the gurney and Jamie forced in the mandatory wheelchair - Jack had to be sedated because he was nearly in hysterics.
And after the hospital staff got Jack and Jamie all cleaned up and put them in hospital gowns and clean underwear, Jack was taken into a room while his arm was more properly treated and Jamie was allowed to sit in (if only because Jack was still crying and moving about even through the sedative in his system, and Jamie being nearby seemed to be the only way to get him to hold still).

When Jack was coherent again two hours later, it was nearly five in the morning and the police had come back to finish questioning. The first thing they asked for was his address. When Jack asked why, they told him it would have to be processed as a crime scene like Jamie's was. He gave it to them, and a few officers were called to go to the house. Between being sleepy and slightly drugged and being questioned, Jack's hazy mind didn't have a lot of presence to question anything anymore.

That didn't mean he didn't have enough presence of mind to nearly start crying again when he was asked to go into detail about what happened after he and the others were taken to the warehouse.

A moment passed as Jack forced himself to keep coherent, and finally he looked down at his bandaged arm with a frown.
"Jamie," he whimpered. He didn't want the younger boy to have to hear this...he'd gone through enough horror just handling Jack in the aftermath. "Leave."

Jamie, who had stuck diligently to Jack's side the entire time he was allowed, blinked at him. Throughout the whirlwind of events happening, he'd felt really...numb. It was all so surreal, and he expected any moment to be woken up and find himself in his bedroom, in his bed. On some level, though, he knew it was real, and he knew he had to insist on staying by Jack's side.
Even his mother was only allowed a brief hello before she was sent off again to sit and wait - Jamie being the only exception to the hospital's "no non-family visitors" rule for obvious reasons. Until Jack was coherent enough to give his consent, Mrs. Bennett would have to sit outside and wait.
It had been a long night, and now the police were back and Jack was kicking him out.

But he knew he needed to stay near Jack, for his best friend's sake.

"N-no, Jack... I want to be here for you! Let me do that, at least. Please, s-since..." Jamie trailed off for just a moment. "Since there's nothing else I can do for you."

Jack stared at Jamie for another long moment, his lower lip trembling before he pursed them and looked down at his lap, body starting to tremble.
A nurse was fixing to sedate him yet again, but he looked up at her and quickly shook his head. The cop held up his hand as well - Jack couldn't give him the report if he was more drugged than he already was.
Jack attempted weakly to shove at Jamie to get him out of the room, but the brunet didn't budge, and finally Jack just turned to face the officer again.

"He... He w-w-was wearing a m-mask...I-I couldn't s-see his face. B-but he... He..." Jack whimpered and used the arm not hooked up to an IV to cling to Jamie for support. "He had us...tied...and...and... He...he gr-grabbed m-me...m-my h-hair...a-and...and..."

When Jack trailed off and shook his head, choking back a sob, the officer reached a reassuring hand over, putting it on Jack's. "If it's too hard for you right now, Jackson-"

But Jack shook his head again. "I-I..."
No matter how long he waited, he would never really get over the horrors. He already knew that. It would only get worse if he held it in and refused to let anyone help him, so he may as well tell the story now instead of having to re-live it all later.
So Jack took a deep breath and tried to put on a brave face, telling them how the Nightmare King had dragged him to each other bound teen by the hair and killed them all one by one...mercilessly. brutally. And while Jack did try to skim over it at first, the cop urged him to go into detail, hoping to compare his story to the evidence in the warehouse to make sense of the attack. The description certainly explained why Jack was so soaked in blood that it hadn't even dried nearly halfway by the time he'd reached Jamie's house, even after about two hours of stumbling around in the woods.
He told them about that, too. After the slaughter, Jack's sleeve had been ripped off at the elbow and his wrists untied for only a minute so the killer could cut his name into Jack's arm, starting at the wrist.
One look at the nurse's face told them it was a miracle that Jack hadn't ended up with a horrible infection caused by cross-blood-contamination.
Once Jack was marked, the Nightmare King bound his wrists once again tightly with rope behind his back. His glasses were removed and a blindfold was tied tightly around his head. Then he was gagged, a cloth stuffed into his mouth, making him retch, before a separate cloth was wedged between his teeth and tied around behind his head as well.
Everything had gone by quickly after that for Jack. He was dragged along by the uninjured arm from the building and into the forest, the rough ground scraping at the bottom of his bare feet, before he was thrown rather harshly into a tree. He told them of how he lay there, sobbing, for a long time before he finally pulled himself up and started stumbling through the forest, hoping to God that he would be seen and helped.
Instead, he'd tripped over a barbed wire fence. Luckily for Jack, the collision had only caused a few minor cuts on his legs and feet, and he'd just bruised his head a bit when he hit the ground as opposed to knocking himself out completely. In a moment of collected clarity, one of the few he had during this whole ordeal, he'd managed to shuffle back until his wrists had meet the barbs and he'd sawed the ropes off of his arms. When he'd gotten rid of his blindfold and gag, he found his glasses strewn on the ground before him and no one in sight.
From there, he'd stumbled around - judging by the vague time frames Jack had been able to give, it was another hour - and everything was kind of a blur.

"Th-the next th-th-thing I-I knew, I-I w-w-was i-in J-J-Jamie's r-r-room..." he finished off, and when he started sobbing again, the nurse sent the cop a questioning glance, tears in her own eyes after having heard Jack's story.
Receiving a nod from the officer, who was also looking rather sick, she quickly hooked Jack up to another dose of the sedative.

Jack was grateful to have the medication surging through him. His body went numb and limp under it's influence, his mind slowed, and his anxiety dropped. Still, though, he sniffled miserably, settling back into the hospital bed and closing his eyes and letting himself be pulled under by the drugs.

Jamie felt sick by the time Jack had passed out, though he still made a point to run his fingers through his best friend's hair and wipe away the tears that fell as he slept - he figured Jack was having nightmares, but he would at least get some rest thanks to the sedative.
He was glad for that...it wouldn't do to have Jack see him now - he was nearly as pale as Jack himself, he was sure. The story Jack told...it was disgusting! Who would do that to someone? Who would do that to his Jack?

The officers questioned Jamie to make sure he had an alibi, thanked him for not cleaning him up and destroying the evidence they needed...and finally left the two boys alone.
When everyone was gone, Jamie was left curled up in the chair next to Jack's bed, staring forward into space.
