"Peter!"

Strange jumped forward, reaching for Peter even as Natasha and Steve lowered him gently to the floor. The doctor immediately checked for a pulse, while Stark stood up so quickly that he almost dislodged Pepper and she would have tumbled to the floor if not for his arm around her. They both moved toward the fallen boy, the chess board and pieces scattering to the floor as well when the table lurched.

Shuri was shocked into stillness, while T'Challa stood, immediately, looking around for an attack, his hand hovering near his chest.

"What's-"

"Everyone calm down…" Fury's voice cut through the startled shouts, and everybody but Strange turned to him. "Doctor? How is he?"

"Knocked out," Strange reported, a wet, cooling, cloth suddenly appearing in his hand. "He's breathing normally, though. Probably a reaction to the Bifrost if that's how Thor arrived…"

"Right." Fury looked at the assembled Avengers. "We've dealt with this before, people," he reminded them, calmly. "Let's not panic. Tony, go meet Thor."

"But-"

It was obvious he wanted to stay with Peter.

"Do what I tell you, son," Fury said, firmly. "It's your wedding and you're the host. Go meet him. Make sure he knows what's going on. Bring him back here for a drink, and we'll keep him occupied while you take a minute to check on Peter – who will be in his quarters," he added looking at Strange and Romanoff.

Stephen nodded, and gathered Peter up into his arms before standing up, easily carrying the slight boy.

"Don't worry, Tony."

Stark looked very worried, though, and he watched with his hand tightly in Pepper's as Strange hurried out of the room, Natasha right beside him.

"Your Majesty? Princess?" T'Challa turned his head from the entrance where Strange had vanished and looked at Fury, and Shuri turned from where she was still focused on the spot Peter had fallen. "Please accompany Tony to greet Thor. You are are visiting heads of state, and it'll impress on our hammer-wielding friend that you're important enough to warrant immediate introductions."

T'Challa could see the reasoning behind that, and agreed – although he was still in shock over Peter's collapse. Fury was calm, though, and exuded authority and a commanding presence. Even a king will respond to that.

"Come, Tony," the Wakandan said, gesturing to his sister to join him. "I am interested in meeting him."

Between Fury and T'Challa, Tony still might have refused. Pepper, however, nodded her agreement, as well, and a gentle squeeze of the hand he was holding hers with drew his attention and he finally nodded.

"Yeah. Come on. We don't want him roaming the compound." He looked at the others. "I'll bring him here. Steve? Will you set up quarters for him for the night?"

If he was here, then he was probably planning on staying until the next day, rather than popping in and out all weekend.

"Of course."

Steve left, and Tony and his little group did, as well, guided by Stark's AI to the proper entrance to greet the god of thunder before he was forced to come looking for him.

OOOOOOO

They made it as far as the corridor outside the lounge on foot, and then suddenly Natasha and Stephen – and Peter – were in the boy's quarters. As soon as she realized where they were, Romanoff hurried ahead and pulled back the blankets on Peter's bed, making room for the doctor to put the boy carefully down, propping him up with pillows that appeared from nowhere.

"Don't look so worried," Strange assured her, a bowl of cold water appearing in his hands with another cloth. "He'd going to be fine."

"He's burning up," Romanoff pointed out, her hand brushing Peter's forehead and then his cheek.

"Yes. We know what to do about it, though," he reminded her. "Let's get him undressed so we can start working on the fever before it becomes a problem."

She did what he said, but Natasha wasn't pleased with Thor Odinson, just then. She'd taken a fright, and he should have known better than to just pop on into the compound when he knew how sensitive Peter was to his Bifrost. Of course, even as she helped Strange pull Peter's shirt off, she reminded herself that Thor didn't have a phone or something to announce he was coming, or to check in. So she wouldn't kill him. She'd just give him a piece of her mind.

OOOOO

"I do not understand, Tony," Shuri said as they walked quickly through the hallways. "What happened?"

"I'll explain it later, Shuri," Stark promised. "But the gist is that Peter's ultra-sensitive to the magic that Thor uses to transfer from here to Asgard – and vise-versa. I should have thought of it, and kept him at the sanctum until Thor arrived."

"Will he be alright?" T'Challa asked, as they went through an exit and found themselves outside, with a very large and imposing man standing there, waiting – assuming correctly that it was easier to wait for Stark to come to him than to go looking for him.

At his feet, the grass was scarred and blackened from the power of the mode of transportation, and in his hand was his legendary hammer.

"Yeah." Despite his concern, Tony smiled as they crossed the grass to meet Thor.

The man was certainly going to stick out at his wedding. Pepper, T'Challa and Shuri all walked with him, and Thor smiled.

"Tony. It is good to see you."

"You, too, Thor. It's been too long."

He held his hand out and Thor gripped his forearm, his grip like a vise, even though Tony knew he was holding back. The god turned to Pepper, and nodded.

"Pepper. Congratulations on your upcoming wedding."

She smiled, too. It wasn't every day you got to say hello to a god, after all – and Thor was handsome and could be almost as charming as Tony when he put his mind to it.

"Thank you."

Thor looked at T'Challa and Shuri, curiously, and Stark was quick to introduce them.

"T'Challa, King of the beautiful country of Wakanda, I'd like you to meet Thor Odinson. Thor, this is T'Challa of Wakanda – and his sister, Princess Shuri."

Thor didn't offer them his hand, but he nodded, politely, his gaze instantly studying T'Challa as if to decide if this king posed him any threat, but also willing to be friends, since he was clearly someone Tony Stark liked. His gaze then went to Shuri, and she flushed, slightly, despite her concern for Peter. Thor was cute, after all, and princess or not, she was still a fangirl at heart.

"A pleasure." He looked around. "Where is your boy?"

Stark made a pained face.

"Yeah… about that. Come on, let's go to the lounge. The others are waiting."

He'd explain on the way and avoid any lengthy conversations about it, if he could avoid it. The sooner he turned Thor over to Fury, the sooner he and Pepper could go check on Peter.

OOOOOOO

He felt them long before he was awake enough to understand what they were saying. Peter knew someone was holding him and that there was a cold cloth sliding along his bare skin, cutting through the almost agonizing heat that seemed to be burning along his skin. That wouldn't have been unbearable, really, but he was aware of the splitting headache even before he opened his eyes, and he couldn't help the soft whimper that accompanied the pain.

"Easy…"

A hand touched his face, brushing his cheek. He didn't really recognize the touch, but he knew the voice, immediately.

"Tony?"

"Yeah, Peter. Hold still, okay?"

"Okay."

He really couldn't have moved if he wanted to. The pain had him almost paralyzed, just then. He felt a cool cloth being draped over his closed eyes, and could feel a gentle breeze from somewhere that seemed to be allowing some of the heat he was feeling to dissipate.

"How do you feel, Peter?"

That was Doctor Strange, Peter knew.

"Hot. Tired. My head hurts."

"We're working on it."

"What happened?" he asked, confused, and unable to remember anything beyond being in the lounge and thoroughly enjoying himself playing chess with T'Challa. "Did I win?"
