AN: A may come back and add more to this. As is, this will stay open ended on how the Avengers react. This was a prompt given to me by Jokergirl4ever
Tony stares at the goddess in front of him, and wonders if he can call his suit to him before she can cast any hoodoo on him like she did Thor. The sudden appearance of the apparent wife of Loki stunned them both and allowed her to bespell the Thunderer. He doubts he can, and if he is being one hundred percent honest with himself, he doesn't want to tempt her in turning on him. Instead, he takes in her long black hair that reaches her mid back, and ice-blue eyes staring down at Thor, he watches in mild fascination as the tiny tot in her arms chews on a handful of her hair. He takes a glance back down at Thor, and a few dots start connecting in his head as he stares at the child that Thor now is. He swallows thickly, and she pins him with her eyes.
"Do not fear, Mortal Stark. I am not here to harm you. I am doing what is best for both my Prince and my husband," she speaks softly, gently removing the hair from the child's- Loki, holy shit she turned them into children- mouth. Loki's face scrunches up as the thing he was chewing on is taken away. He can't be more than three, maybe four.
"You and the others will watch them, will care for them," she says, her fingers rubbing Loki's cheek.
"Yeah? And why should we watch the terror in your arms?" his mouth moves without his permission, and her eyes narrow at him. The air around them shivers.
"Because, Mortal Stark, the best sorcerer is the one on your side, the worst is the one who wants to rip your spleen out of you while you still breathe," she says with a sharp, feral grin, "And I am not a sorcerer you want on the wrong side."
Tony scoffs, not because he doesn't believe her, but because if he doesn't he may whimper. She doesn't see it that way and takes a step closer to Tony.
"I broke into your tower and turned one of the strongest gods into a small child. Do not underestimate me. I will know if any undue harm comes to Loki."
With that said she places Loki down at beside a still stunned Thor- seven to eight at the oldest- and then blinks out of the tower.
"Well shit," he breathes out, "Jarvis who else is in the tower?"
He squats down next to the two children, worry eating away at his insides. Children aren't something he has had to deal with often, but he's pretty sure they are louder than these two.
"Doctor Banner is currently the only person here, Sir."
"Excellent. Ask him to come up here?"
"Yes, Sir."
Tony nods and tilts his head at Loki and Thor. Thor is finally doing more than blinking his eyes and is instead looking around the room like he doesn't remember it. Loki, the little menace he is, has a death grip on his brother's arm.
"Hey there, do you know who I am?" he asks them, dreading the answer from the way they both jump. They both shake their heads and Thor pulls Loki behind him, giving Tony a look into Thor's life before Loki went full bag of crazy.
"Where are we?" little Thor demands with the cutest little pout that is supposed to be fierce. Tony smiles at them, trying to look harmless.
"Your nanny decided that you needed a Midgardian adventure," he tells them, hoping it will be enough to cool their jets. Thor likes to tell stories of the 'adventures' he and his brother got into in their youth. However, Loki leans up and whispers into Thor's ears, and it makes Tony narrow his eyes. Thor speaks up.
"Loki says that you are lying."
Thor wiggles his arms, nearly tripping on too big clothes in an effort to grab Mjolnir. Kind of a dick move Sigyn, he thinks, giving clothes that fit but leaving Thor to struggle.
"Alright, Reindeer Games can tell when we lie, that is a new power, good to know. I am Tony, and I am a friend."
Reindeer Games studies him a bit, his green eyes narrowing before he leans in again.
"We do not know who this Reindeer Games is, but he says, this, at least is truth."
He hears the elevator ding behind him and lets out a thankful sigh. When Bruce comes into sight he stands.
"Brucie baby! These are Loki and Thor, they were dropped off for us to babysit by an older Asgardian," Tony says with a flair. Bruce, bless him, merely raises an eyebrow already used to the insanity that comes with being an Avenger.
"Hello boys," he addresses the boys before turning to Tony, "Do we have a pickup date?"
"Nope," Tony pops the 'p' and enjoys the fond eye roll he gets from Bruce. There is a tug on his pants leg that makes him jump slightly. He looks down and spots Loki, who has Thor scowling at him, looking up at him.
"I need wee," he whispers. Tony's eyes widen, want to get the miniature god to the bathroom quickly he bends to scoop Loki up only for him to bounce away from him. Bruce bends down.
"I can take you to the bathroom," he says, and Loki rushes to him.
"I need wee," Loki repeats. Tony is left watching his science bro walk down the hall to the bathroom with a baby Loki looking at him like he hung the moon. Thor not to be left behind, and knowing that his clothes will slow him down gleefully strips down, and takes off running.
"Oh, this is going to be fun," Tony groans, "Jarvis order clothes that should fit children around their sizes."
"Of course Sir," there is a quiver of amusement in Jarvis' voice that has Tony rubbing his temple.
"Karma," he mutters, "this is karma for all the times I drove my nannies nuts."
He hopes that when this is all said and done with, they don't have a revenge seeking trickster on their hands…
"Shit. Let Barton know we have certain horned company, and if he doesn't think he can play nice… I will take the kids to the mansion so he doesn't have to avoid his home."
"Right away… You may want to go assist Doctor Banner. Loki and Thor have discovered the wonders of facets."
Tony laughs and follows the sound of childish laughter. Maybe this won't be so bad.
