There was a short, bumpy slide down his rump before he was left sprawling in a pile of dirt in a dark tunnel as their next destination. Sirius tried to sit up and then grunted in further pain as several more people came tumbling down on top of him.

Maneuvering and cursing helped sort it out, mainly the second, and soon they all found themselves able to hunch over uncomfortably, but they'd been in worse places recently. He didn't even need Evans to light her wand to tell him where they were though, he'd know this secret passage as well as his own dorm room. The sharp windy breeze discernible above his head, the faint, musty odor of blood and dust ahead, the way the path was slightly less well worn than any of the other hidden tunnels they'd ever found, though that was quickly being changed the longer the Marauders knew about it. They were underneath the Whomping Willow.

He didn't need Remus' soft little whimper of worry, James subtly stepping between Moony and everyone, or Peter's awkward shuffling backing away from everyone to know why this put them in such an awkward position. The only conceivable reason to them why Harry would be down here, is that one of the Marauder's had taken him down here for some reason. Neither of the present two seemed to have much of a good reason.

Waiting in the dust at the end of the slope was the now dusty purple book, sitting innocently with the pages now smattered and crumpled from so many people kicking and landing on it as they went past. Sirius swallowed a bit of bile as he went to pick it up, but he ignored his hand shaking as he met Remus' eyes and tried to concoct a plan for the worst.

If, and it was still a very big if to him, Harry was somehow down here because he found out about Moony and had some cacamaime idea about seeing it, the three friends in this time would have to do a hell of a lot of covering up for their Remus now to make sure none knew the wiser it wasn't true now. He gazed down at the chapter title for too long, Frank began laughing at what the hold up was. As an experiment, he tried to laugh and summarize the odd chapter title, just telling everyone else it was a bunch of animal names, but no more words appeared until he finally said Cat, Rat, and Dog.

He couldn't fake it. He didn't know a way how to talk them out of this one.

It didn't start out with any good omens, what with Buckbeak being unjustly killed and the poor trio's reaction. Then Scabbers started going nuts, the reason being quickly revealed Crookshanks was still after him. Still he could hardly spare any of it a thought as the tunnel subtly shifted in size around them, though he really couldn't care less now he could stand up straight instead of hunched over the book.

Then the dog arrived.

He startled so hard he scraped his head against the ceiling, causing a slight dust cloud around him and poring over the book. He took the temporary coughing fit this caused amongst the others to gaze at his friends in pleading silence to tell him he'd read that wrong, but their shadowed eyes gave nothing away.

Sirius had started this worried about how Moony's involvement was going to get dragged into this and what potential secrets was going to come of that, now a whole new scenario was playing out behind his minds eye. The deranged animal he'd become in Azkaban, sapping away his humanity and leaving him with one animal urge left to kill, somehow being directed on one he'd so love.

A puddle of sick was there at his feet, and he didn't even remember doing it. His throat still burned, his stomach rolled and threatened to continue any moment, but all he felt was the horror his mind had latched onto and wouldn't let go. He'd gifted himself this animal form to save Moony, now it would be the death of James- Harry- James-

"It's alright Padfoot-"

"Let it out mate."

"How hard did he hit his head? Did he give himself a concussion?"

It all swam before him like he was seeing the three from underwater, he was afraid to clear his gaze and find out what was holding him upright, but James was there. His best friend was undeniably keeping him on his feet, not the wall. Remus and Peter were promising in every way but words that no matter what that monster of their future did they weren't going to pin the blame on him now. Even Regulus was bouncing on the heels of his feet and eyeing him in concern rather than criticizing anything for once. He should feel safer than ever, but he didn't know how to shake loose the terror lodged in him, had zero faith he could say the words that he'd killed his godson.

Wormtail finally took pity on him, and after several Evanesco spells to pick the book back up, gave them all a confident smile he could somehow make this easier on everyone if he was the one to say it.

The madness didn't sound much better coming from him, as Ron was somehow grabbed instead and dragged along into this very tunnel. Sirius could swear he could identify the very streaks of blood in the dark lighting. It didn't work the sanity back into his favor any. That wild animal seemed determined to kill and had just grabbed the wrong kid. Did that mean something of him had spared Harry at the last second, or was he so gone he couldn't even be bothered to care anymore.

He tried to fight that off, surely if students had been attacked and killed all year they would have heard of it! Was this the first time then, and he'd been building up to it?

Harry and Hermione went after them, to no one's surprise, but too late the Marauders misunderstood the look of dawning determination the four outsiders had on the Marauders.

Potter didn't make a joke about saving another redhead in distress with a salacious look at Lily, Lupin wasn't hovering in the background with suppressed laughter but was now the one with a supporting hand on his friends shoulder and trying to whisper words of comfort for no one else's ears. Pettigrew was reading like an ancy toddler, his voice stopping to squeak uncomfortably every time he stopped for breath.

Of course they'd be worried about Potter's kid, that wasn't unreasonable as they'd all made it clear from the beginning they'd been invested in this future and Harry. Their distress over Black's fate of being an escaped madman had also been perfectly reasonable, if a little blind to some of them early on. Now with time on their side they'd finally conceded maybe all of Black's actions weren't so black and white, and it wasn't Potter being comforted for the fate of his child they were watching.

The idea, the unbelievable, illegal, but slow forming understanding had hardly taken root before it was slapped in their faces. Sirius Black was an unregistered animagus, and his friends knew it.

"You idiot," Regulus told him with pure sincerity. He would have decked him if his brother didn't look so miserable already.

Sirius was exhausted. He'd spent countless hours now being hurtled through someone else's life with company he wouldn't have asked for, now he'd been living through countless hours believing himself a madman and a murderer which finally seemed irrevocably true. He didn't know what would happen to him if this secret was told, but surely a fine at the worst, which still wasn't as bad as Moony's secret being revealed. He was tired, so he didn't deny it.

"I don't understand," Frank muttered, looking between the four. "You must have a reason for doing this, even you lot know this is more than breaking a school rule for kicks. What possible reason-"

"He doesn't have to explain himself to you even if he did know," James snapped, his every breath trembling with nerves. The nightmarish image of Sirius dragging Ron off, his own self congratulatory words Harry would follow wasn't adding up to him. If he'd wanted to kill Harry than he'd had opportunity enough, something else was going on here, and he was already getting a headache trying to follow along, let alone fending off their prying questions.

It fooled no one. They all knew now, and no one was sure how to go forward with the information.

Sirius couldn't stand there any longer, avoiding their eyes, doing nothing. So he snatched the book back from Wormtail as he took another trembling breath, reading out in his own harsh tongue the tussle between him and Harry, the thirteen year old kid actually winning with the help of his friends and then considering murdering him. He almost wished Harry would, put him out of his misery those dementors had trapped inside him.

Then Remus was there, offering backup Sirius had never asked for but always seemed to find when he least expected it. Sirius wanted to fall into his arms now, sob in gratitude he wasn't alone in this future and Moony was still there for him, something still made sense. The only thing stopping him was the fear of drawing attention back to Moony, the one Marauder who had another illegal secret much more dangerous to have the spotlight on, in a house they were far too close to, with a night ahead they had no absolutes about.

It was all in vain as Hermione ousted him, after he'd finally been able to get his feet under him. Sirius took a deep breath, threw back his shoulders, and dug into every bit of collective knowledge he'd acquired over the past fifteen years of his life as he turned to Remus and said, "and I thought I was the monster in there."

It was there for just a second, the flicker of hurt, the shadow of true fear at those words finally being flung in his face, but he also knew Sirius. He'd seen the true look of disgust on his face directed at other students for whispering about werewolves after a they'd come up in a lesson. He'd heard the true tones of unforgivable loathing every time he looked at Snape. This was Padfoot covering Moony's tail and leaving his own hanging. There was every chance it wasn't going to work, but he smiled at him all the same for trying.

James slugged Sirius in the shoulder and called him a jerk, trying his hardest to sound like he didn't mean it. Peter had perfected the art of an awkward laugh and shuffled even farther away, keeping his hands behind his back to now show them trembling with nerves at being caught.

It might have actually worked, had they not spent every other available moment defending one of their own against another equally radical claim. Now, their blase brushing of this off just gave other moments a chance to make a lot more sense.

Frank recoiled, waiting for his life to flash before his eyes as he realized the danger they'd been in without even realizing it. He went back and counted, almost kicked himself for each clue he'd overlooked. What being an illegal animagus had to do with it, or even if the two were cause and affect he still wasn't sure, but he grabbed Alice's hand and began trying to pull her as far away up the tunnel from the rest of this insanity as he could. They hadn't asked for this.

Alice jerked her hand away with a scowl at her boyfriend, she hadn't grown up with the prejudices she knew most purebloods had gained. Her parents were aurors, along with her grandparents, she was descended from the first set to have ever gotten the job. She knew from countless stories what it felt like to be victim and hero, and right now she saw Remus Lupin, hovering terrified behind his friends, as an innocent person just like her.

"Frank!" She protested as he hesitated. He didn't continue backing away, but he didn't look much ashamed for his automatic reaction, nor her tone.

"You don't want to hear the stories my mum's told me about werewolves-"

"Your mum sounds like a paranoid git the more I hear about her," Alice crossed her arms in frustration. "I've heard things from my parents too, and they're not just stories. Those poor creatures live in poverty, most of them just kill to survive-"

"Oi! Do you two mind having this conversation like he's in the room," Sirius Black took a dangerous step towards the pair, even in the near darkness they could see the anger coming off of him, as Lupin shuffled even farther away from all present in shame.

Sirius regretted his outburst at once. Five years of ignoring other kids whispered comments about this and he'd caved now, but he couldn't just shoot a hex at them and laugh it off like his usual prank, Remus couldn't just pull him along to the next class muttering to him how much it didn't matter.

Peter, to his credit, still tried as he pipped up, "yeah, how would you like it if we started laughing about how your future turns out? Oh wait, we don't even know yet!"

"Oh don't kid yourself Peter," Regulus rolled his eyes. "The man himself hasn't even denied it, and you lot are actually terrible liars." He was slightly paler under his dark hair than usual, his eyes remaining trained untrusting on the outed party, and every terrible lesson he'd ever been through with his father over dark creatures was playing back through his mind, but for once in his life Regulus was trying to drown out every outside voice but his own.

He wasn't sure how much he could trust Sirius over his own parents, he'd thought his brother had never lied to him but now even that was wrong. Now all he had left to feel were the two contradictions of his life, the lies of You-Know-Who's heritage and his own. If he'd been wrong about that all his life, what else was he wrong in assuming straight from his parents?

Lily wondered if she was going to be sick. Her first thought was that it made a horrible kind of sense, the cruel lot of friends had found each other, of course Potter and Black would accept a werewolf as a friend considering they showed no mercy to their own victims of those horrible degrading acts they called pranks.

She looked again though, really looked at them. Remus Lupin was a scared, pale teenager watching those around him take in this news as he hovered behind his friends. No 'monster' could ever look that vulnerable and be a pure killer. Peter Pettigrew was looking between them and his friends, like he was waiting for a signal what was going to happen next. He still trusted his friends to make that decision so he could go along, while those horrible friends of Severus', even Sev of late followed blindly with the first thing they were told by their superiors without thinking twice about it. Sirius Black was being accused of murder, now of his best friends son, and he still stood right beside him as if at any moment he was going to be that killer for his friends. James Potter stood as their center, every bit their good influence as he was the bad.

Silence like none before lay thick in the air, each person waiting for someone else to make the next move. Sirius reacted first, it was his sanity on the line here, and even with Remus involuntarily being thrown into the mix in this future, it was still his sanity on the line. He snatched the book away from Peter and read in a blur. He wished his future self would give Professor Lupin a kick for tottering on about Sirius dragging two people into this passage, about focusing on Ron's pet of all things.

He cursed the man having to over explain everything now of all times as none of it was making any sense. How was any of this helping?

The mental tirade came to a halt as Sirius Black, the escaped prisoner of Azkaban, finally answered who had done these true crimes all along. Peter Pettigrew.
