Percy is still lying on the floor of - what is definitely a high tech – cave, when he fully regains consciousness, and now there are various costumed kids – preteens and teens – peering down at him with various weapons in hand.
He – having his priorities straight – ignores the weapons in lieu of looking for his friends or more importantly Annabeth. He finds them lying beside him in various stages of consciousness. Annabeth is lying right next to him and as his eyes rove over her, searching for any injuries, he notices the guy right beside her who is being assisted onto his feet by someone with white hair in a crew cut. It's Dick the guy from a alternate universe full of costumed people.
Now Percy isn't the sharpest tool in the chest but he can put two and two together and garner that this time he's the one who has traveled through dimensions to land in another world.
He lets out a groan involuntarily, and tries to sit up, turns out – bad move. He freezes as the weapon laden kids move as one to aim all their weapons at him. Because Percy has watched a lot of action movies he knows the right thing to do is raise his hands to show that he comes in peace, but because Percy is also a fool what he does is ignores the possibly lethal weapons pointed at him and goes straight into make-sure-Annabeth-is-okay mode.
His hands reach for her neck to check her pulse, as soon as his fingers make contact Annabeth starts stirring. He lets out a sigh of relief and moves to cradle the back of her head (still ignoring the various definitely lethal weapons pointed at him) to help her up and because Annabeth is more tactful than he is, she raises her hands as soon as she notices the hostile kids. Around them the rest of the seven and Nico and Will, are coming to and raising their hands in a show of surrender to these weird costumed kids with weapons.
Percy out of sheer stubbornness keeps his hands down at his side and instead gives a once over to their hosts. There are 5 people, one 12 year old green skinned boy with a tail (Percy would be surprised but he is brothers with a cyclops so….), one green skinned 16ish girl (must be related to the boy) floating in mid air, a blonde girl decked out in orange and black pointing an arrow at him, a very angry young man teen in a black t-shirt with an S printed on it and finally the white haired guy with a crew cut who is helping Dick stand up with a glowing blue sword in hand and gills?.
"Who are you and how did you come here?" the boy with the black t-shirt demands in a gruff voice, "What were you doing with the civilian?"
Civilian? Percy is stumped by that but then he follows his gaze to Dick and upon realizing whom he is referring to, like the stupid person he is blurts out "You mean Dick?"
The reaction to his statement is like the audience response to a shocking scene in a variety show, by which he means some people let out gasps and the blond girl's grip tightens on her bow and the gilled guy and angry young teen let out growls in harmony.
Percy recognizes the look on angry young's face – its an expression he has seen innumerable times on Ares' kids faces – it means that it's the time to beat someone up for answers. Percy would feel fear (the guy is quite buff) but after Tartarus not a lot scares him.
Before any of them can make a move a voice interrupts, "its okay Conner they aren't the enemy, they are good guys. Put down the bow Tigress."
The level of menacing lowers and the greenie girl swoops down to give Dick a hug. "I've missed you, where have you been." Percy hears in his periphery but his attention is more focused on getting up and helping his friends up, checking if anyone is injured and if anyone has a concussion.
By the time they all have got their bearings and Will is fussing over Nico the costumed kids have finished with greeting Dick and are now starting at them with suspicion
"So, are you going to explain to us what is happening Dick." The angry young teen grunts.
Dick looks conflicted and stares towards Annabeth for assistance (his expression is pained as if looking for assistance is the most difficult thing he has ever done).
"I think we should be sitting down for this." Annabeth lets out a sigh.
Dick's head was still ringing from his previous inter dimensional journey, the second one had almost completely fried it, so he was eternally grateful when Annabeth requested that they sit down.
The request also worked to divert the attention from him. He had left the team without as much as a goodbye, only a note explaining that he would be unavailable for the foreseeable future as he searched for a way to bring back his friend. His sudden appearance via a flash of light must have caused questions to appear in his teammates' minds.
Right now he had no answers for most of the questions that they would probably have the best he could do right now is recount what has happened since the his world began to go topsy-turvy.
So he does just that, they lead on into the kitchen/sitting area (it's the only area which does not contain incriminating evidence of their superhero-ness), he starts with him disappearing from Greenland and appearing in another dimension where he meets Percy and Annabeth, discovers he is in another dimension, goes into an emergency meeting where he meets the rest of the people, finds out they are children of gods-
"You are children of who know?" Beast Boy interrupts before he can continue.
"Shh Garfield that's rude." Megan reprimands immediately.
"It's okay I would want clarification too if I was in his shoes," Annabeth defends, turning her attention to Garfield she informs him, "My mother is Athena the Goddess of wisdom and battle strategy. In our dimension the Greek gods are alive and active sometimes they fall for mortals and that results in us – demigods" And then gives the rest of the crew a look that immediately prompts them to start their own introductions. And you have to give it to them-the members of the team take it all in stride, with a few exclamations here and there as they recognize the names of the various gods, even when Nico grunts out a 'Hades, God of the underworld' just a 'c-o-o-l' escapes Dick's mouth who is getting the introductions for the first time too.
But when its Percy's turn, as he reluctantly unfolds his arms heaves out a big weary sigh and mutters out a, "Poseidon, the God of sea and storms."
The reaction of one person is overly exaggerated, as Kaldur suddenly drops to his knees, his fist on his heart and head bowed and exclaims, "My lord."
"Umm…. What's happening? Dick?"
Dick meanwhile has been snickering into his hands. "Sorry. So Percy, prince of sea meet Kaldur an atlantean" and then in a mock whisper "Poseidon is their Patron God."
"Oh that explains the gills." Annabeth nudges him pointedly.
Percy noticing the still kneeling atlantean startles, "Yeah. Oh, you can stand up now?" He finishes uncertainly.
Kaldur gets up, his fist still on his heart.
"Chill out man Percy is not that special." Dick said flinging his arm over Kaldur's shoulder.
"Hey!" Percy Exclaims. "But yeah I'm not special or anything, so you don't have to treat me any different from others."
"How are we supposed to be treating you people." Garfield questions curiously. "Because no offense but you are children of gods from another dimension."
"Well," Annabeth starts, "aren't you all a bunch of overpowered individuals who save the people from time to time?" she waits for muttered yeses and nods, "well so are we, umm most of us any way."
"when you say most of you, you mean…" Megan trails off.
"Annabeth here thinks that she has no powers. But in truth her brains are a more powerful weapon than most of our swanky abilities."
Annabeth hits him in the stomach with the back of her hand "Swanky? Really?"
"Well anyways…" The blond guy with the scar on his lip interrupts before they can get into a fight (which seems like a common occurrence really). "Jason, son of Jupiter or Zeus in his Greek form."
"You are a son of Zeus? Wow! Me too. I mean daughter obviously because I am a female but a daughter of Zeus. Cassandra at your service but you can call me Cassie."
This prompts the rest of the Young justice members to start their introductions, Conner is reluctant but even he grunts out his name adding a Superboy, as the others have also revealed their own aliases. Dick feels like he should be doing something like taking charge of the situation but after being gone for so long he is reluctant to. So he is abundantly thankful when Annabeth diverts everyone's attention to the matter at hand.
"Now that the introductions are out of the way I'll like to know why we are here? I have never heard of interdimensional travel before have you?"
Most of the people shake their heads. But Dick remembers something and contemplates the information before speaking.
"Guys remember that time Klarion created the alternate universes?"
"Yeah." Superboy replies, the incident coming to the forefront of his mind. "One in which adults existed and in the other children."
"That's some high class magic." Annabeth whistles. "Do you think it's the same guy this time too?"
