Notes: So, I'm doing something a little different for the next two updates. I decided to try my hand at combining prompts and this is what happened. The prompts I used were 21 and 22 from the febuwhump.Tags: nothing much just basic whump I guess?

It was a hot, yet pleasant, summer day. The temperature was only at 89 or 90 F, which was normal for the lake house. He felt pretty hot but figured it was from running and playing with Morgan. He'd jump in the lake to cool off later.

"Come get something to eat and put some more suntan lotion on you two!" He heard May call out to them.

As he turned to head to the picnic table that had been set up near the edge of the lake, he felt the blood rush from his head and suddenly felt as if he was in a sauna. He stumbled, vision blurring before turning black as the ground rushed to meet him.

Peter didn't understand what was happening.

He felt as if he was underwater. Everything around him was blurred and distorted. He could hear familiar voices but couldn't make out what they were saying. Before he could try, his world turned from being underwater to an earthquake.

Suddenly bits of voices started to break through the haze that still seemed to cover him. He heard muffled shouts of 'heat-' 'too much-' 'pulse is through the roof-' 'temperature too high-' 'not sweating-' 'shit!-' 'call Bruce-' 'seizing-'

Peter's world was burning. He felt as if he was stuck in an ocean of pain and fiery torment, drowning with no way of reaching the surface.

It reminded him of when he was tangled in the suits parachute, when Tony had sent an unmanned suit after him. The only difference was that he felt fire instead of the icy coldness of that moment.

He was simultaneously burning, shaking and drowning. He didn't understand what was going on.

The call of unconsciousness beckoned him. He let himself fall.

Peter woke to a beeping sound and the weight of a hand on his. He slowly opened his eyes, groaning as the adjusted to the bright lights of what he now realised was the compound med bay.

He moved to try and sit up but a hand on his chest stopped him. He looked up into the worried eyes of Tony.

"Wha' hap'nd?" Peter asked voice slurred from residue sleep and exhaustion.

Tony looked at him carefully for a while. "You went into heatstroke, Pete. You just collapsed. By the time we got to you, you had already started seizing." He eventually said. "I called Cho as soon as you went down and she had me send you here in a suit as soon as you'd stopped seizing."

The residual fatigue was cleared as Tony spoke.

It made sense to Peter now. The voices and feelings he'd had.

He looked at Tony with questions eyes. "Do you know what happened yet?"

Tony picked up the tablet from the table next to Peter's bed. Pulling up a hologram he passed it to the teen in the bed.

"Your thermoregulation doesn't just apply to the cold, it carries over to heat as well. Where a normal person is able to regulate their body temperature and stay cooler, you don't have that. Basically, it's your winter thermoregulation problems in reverse." He said as Peter looked at the information on the tablet.

"Your metabolism sped up and boosted the effects. That's why it hit you all of a sudden."

Peter nodded. Contemplating the new information. "So metabolism paired either higher or lower temperatures equal possibility for lethal results. Got it. Guess that means no trips to the Sahara or the Antarctic then." He ignored that annoyed look he received from Tony. He coped with stress through humour. Tony should know that by now.

Peter sobered. "It was freaking scary but I guess we'll get used to managing it like we have with the cold side, huh?" He said passing the tablet back.

Tony set the tablet back on the table. "Yeah, we'll get used to it."

"Just try not to pull too many of these stunts, please?" Tony said, "Cho and her team like you but they don't want you to be a permanent fixture here."

"No promises."
