A/N: Here's part 3 of the "Mines" storyline! I'll be posting the final part in accordance with the Day 6 prompt, so tomorrow's will be a little different, but unlike yesterday's prompt, will be a lot more lighthearted xx

The dust had already settled by the time Peter returned to consciousness. Not yet ready to open his eyes, he instead took mental inventory of each of his limbs, and he had to swallow back his panic when he couldn't move his right leg without white hot pain licking its way up to his knee. In that moment, he made the decision to force his eyes open, hoping like hell that he wouldn't be greeted with some sort of compound fracture or something else disgusting. Peter considered himself anything but squeamish, but he'd seen more than his fair share of gruesome injuries that he could very much do without at that very moment.

He found the offending object quickly; a large boulder the size of a washing machine – yet at least twice as heavy – sandwiched from halfway up his shin to his ankle. Mentally counting to three, he braced himself for the pain as he gave his leg another tug. He groaned through clenched teeth, clenching his eyes shut at the feeling of bone grinding on bone. Yep, definitely broken.

There was also a secondary problem he had just identified – the surrounding rocks had shifted in response to the movement of the one pinning him down. Peter watched with bated breath as a few stones the shape and size of watermelons tumbled down from the top of the pile and narrowly missed Ned, who still lay unconscious and prone on the ground beside him. His backpack lay just behind Ned, situated near what remained of the steel support pillar. If Peter remembered correctly, that meant that they were stuck in the middle-left portion of the cave. If he could get to the suit, he could get to help.

This would be the most high-stakes game of Pick-Up Sticks he'd ever played.

Tony had received a notification about Peter's suit, and as much as he'd later hate to admit it, he had passed it off as unimportant as it initially came through his systems. Tony was in the process of finalising the last of the data transfers to his new lab in the Avengers headquarters that had been relocated to upstate New York. Terabytes didn't even begin to cover the quantity of files he had left to integrate into the new systems, but he had to start somewhere.

The hard drive had now begun to transfer the new blueprints for the latest Spiderman suit upgrades Tony had started prototyping. Peter was a keen kid; he was passionate and excitable, but frankly the sheer amount of voice messages he left was bordering on a violation of privacy. As Tony scrolled through the massive folder on Peter's latest web-formulas he'd devised, the regular 'Peter' blip that appeared on his radar had suddenly faded into nothing, prompting advisory from F.R.I.D.A.Y.

According to his A.I, Peter's whereabouts had last been defined as being circa upstate New Jersey, close to - if not within - the Sterling Hill Mining Museum. F.R.I.D.A.Y further informed Tony that that particular area sat right near the Ramapo fault line, where seismic activity had recently been detected.

Without hesitation, Tony set each foot in front of him deliberately, finally shrouding himself in his latest nanotech development: The Mark…whatever the hell. It was fast approaching the seventies and Tony had long since lost count.

The built-in stabilisers in the suit prevented Tony from feeling the G-Force he would otherwise be subject to as he catapulted towards northern New Jersey. He'd asked F.R.I.D.A.Y to inform him if any changes occurred regarding Peter's whereabouts, however his radar remained silent apart from where the calculations told him Peter's last known location was.

Completely removed now from the dense concrete jungle, Tony reached his final destination just outside of the Mining Museum. It may have been a long shot, but there was no way in hell Tony was leaving a single stone unturned.

Peter had nearly managed to sling his pinkie finger around the inside of his mask that was sitting inconveniently just past the middle of his backpack. If Ned's life hadn't been at a perpetual state of risk from a catastrophic cave in, Peter would have simply yanked his leg free long ago and dealt with whatever consequence, but when it was a life other than his own, he found himself unable to act irresponsibly, instead finding himself performing 'babysitter' duties whilst pinned underneath a rock half the size of his apartment fridge.

Simultaneously extending his left arm once more as he gently shifted his leg just a fraction from beneath the boulder, he silently cheered as he managed to get a concrete hold on his mask. If anything, if he were lucky, he would be able to contact Mr Stark and work on getting them both out of here.

Pulling the mask over his face, he heard Karen's calming voice as whatever systems were available initialised. He assumed he had a concussion at that point, as barely anything she said was properly registering for him, and simply went in one ear and out of the other.

"Communications are now online," Karen hummed, and Peter sighed with relief. What he didn't expect, however, was the almost instantaneous interception of Mr Stark's voice through the comms.

"I leave you alone for five minutes...what the hell happened, kid?"

Peter grinned from within the mask. He knew he was safe. Tony Stark had come to get him, and everything would be alright. Ned would be left unscathed and before he knew it, it'd all be a distant memory. "We were on a field trip, and all the rocks were really cool, and then suddenly the ground started shaking, the cave collapsed, and now I'm stuck in here with Ned who's unconscious, by the way, and - "

"Take a breather, kid. Just sit back for a minute, F.R.I.D.A.Y's pulling up a map of the mine. We'll get you out of there, try not to move too much, okay?" Tony's eyes shifted over the heads-up display, taking in the various patterns of disarray with Peter and Ned laying in the epicentre. He narrowed his eyes as progressively more shapes on the close-proximity radar turned a bright shade of red. These boulders couldn't be moved unless Peter wanted to put the lives of himself and Ned in immediate danger. It was time to change games and play Tetris, but this time lives were at stake.

"I need you to listen to me, Peter. There's a rock to your right. Do you see it? I need you to wedge that just under where that boulder on your leg is sitting."

Peter wasn't about to question how Tony had gotten there in such a short amount of time, or how he knew about the offending boulder atop his ankle. Following Tony's instructions, he shifted the stone next to him, and was able to use it like an 'a la natural' forklift to shift the stone from above him. He pulled his leg out as fast as he could in the fear that the rocks above him would crash down upon him - but this time more catastrophically. Ned still hadn't come to, and Peter was becoming increasingly concerned for his friend's wellbeing. "Okay Mr Stark, I'm out. But Ned, he's still not waking up, I don't know what - "

"One thing at a time. Now, I want you to -"

Peter didn't register what was being said to him, instead taken over by the sheer sense of dread as he fully realised the proximity of the rocks sitting around him, trapping him on all sides. As if that weren't a big enough concern, one millimetre of uncalculated movement could cause a cataclysmic cave in that - if Peter lived - he didn't want on his conscience.

F.R.I.D.A.Y displayed the increased pace of Peter's heart rate, and the decreased oxygen saturation in his blood. Shit. "Peter, I need you to listen to me. You can panic when this is over, believe me, but right now you need to get out. There's a small rock to your left that's shaped like the Kmart version of Cap's shield. Nudge that out of the way for me."

Crushing his fear down as far as he could, Peter rapidly identified the frisbee-shaped stone diagonally to his right. "B-but Mr Stark, that's right underneath a massive pile of rocks…"

"Think of this like…" Tony rummaged in his brain for a moment, warring with the part of him that craved a blunt and harsh approach to the situation. He knew that would only cause Peter to stress more than he already was, so he opted for the approach that was as calm and collected as he could muster despite the situation. "What's that game you showed me last week, kid? The one with the wooden blocks?"

"Jenga?"

"That's the one. Sometimes stuff's gotta fall down before you can stack it up again. Don't worry, F.R.I.D.A.Y's got your back." Tony worried at his bottom lip, hoping like hell F.R.I.D.A.Y hadn't made some critical mistake in her calculations. He was purely relying on her to get Peter out of there. From where he was standing in the sole connecting tunnel that would lead to freedom, all he could see was rocks, rocks, and more goddamn rocks. As much as he would love to tear them from where they were positioned to get to the kid - his kid - he knew that any rash mistake on his part would end with more than one life haunting him until the day he died.

And so a game of Jenga they played, Peter pulling stones from one location and sliding them to become the new support structures for other smaller micro-towers. The space around him began to expand, and with it, Peter felt as if there were more breathable oxygen seeping in through the cracks between the stones, and he wasn't sure if he was imagining a gust of wind blustering in from where he guessed the tunnel's entrance was. He had no idea how long they'd been reshuffling the contents of the cave, but Peter could almost stand completely upright and walk about twenty feet to his right and left.

"Alright, now this one's gonna be a doozy. There's a small pocket in front of that big boulder over there. Just give it a good kick." From what Tony could see on his monitors, the moment that large rock moved, he would be free to blast the remaining stones and drag the kids out of there, no matter how many pieces they were in.

Peter knew this would be painful. It meant one of two things: he'd have to do the kicking with the leg his busted ankle was attached to, or he'd have to put all his weight on that limb while he did the deed with his good leg. Either way, he was prepared for it to suck. Choosing the latter and supporting himself partially on one of the larger boulders to his right, he brought his left knee to a right angle before pushing out with as much force as he could muster.

Tony first heard and then saw the shifting of the obstructions before him, the remaining fragments tumbling from the top until they sat in almost neat little piles below their larger counterparts.

Finally overwhelmed with exhaustion, pain, and the intensity of the last (at least) hour, Peter lowered himself onto the ground beneath him, only vaguely hearing metal scraping on stone, and the vibrations in the ground as Tony completed the last of the puzzle.

As he felt himself losing grip on awareness, he only just felt himself being gently lifted. At long last, feeling safe in the arms of the man he considered to be his father, he let himself drift off into the realms of unconsciousness.

A/N: Finally he's out! Peter and Tony will definitely be having a conversation about it on Day 6, so make sure you stick around for the conclusion to this little short story. I hope you've all enjoyed it so far xx
