Aqualad shakes his head at Kid Flash. He steps forward and bows, placing his hand on his chest. 

"It is an honour to meet you, Yvette. I am Kaldur'ahm, known on the surface as Aqualad." 

Oh goodness this is a large number of people her age all focused on her at once, eep.

"Honor to meet you too," she says politely to Kaldur, then looks at Kid Flash again. "Uh - whichever you like? It's your secret identity, I'm not going to demand it of you."

"Well, if Aqualad's doing it - hey, nice name by the way," he tells Kaldur.

"I guess you guys can call me Nate." 

"Don't call him Nathaniel," Robin contributes. 

"I'd jump on the bandwagon, but Batman won't let me tell anyone my secret identity." 

Blink.

"Uh, okay. Nice to meet you all."

Can he celebrate this with a hug? Because he'd like to! Hmmm, but who to hug...

Eenie, meenie, miney... sister!

"Eep," says the sister in question, then she snorts.

"This is my penance for teaching you about hugs, isn't it."

"Yes," agrees Rain, sagely.

Robin hops up onto the kitchen table and sits there swinging his legs. 

"So, what were you doing with the microwave?" he asks Yvette.

"Oh, it's magic now. Well, partially. Self cleaning, will try not to leave weird cold spots in your food, won't turn on if you put a cat in it, that sort of thing."

"A necessity I'm sure won't be tested," says Batman, showing up out of nowhere as Batman is wont to do. He looks at Robin. "Is that a chair?"

"...no?" 

Pouting, Robin pushes himself off the table and drops back down to the floor. It looks less impressive than usual without his cape flaring behind him. 

"Thank you."

He looks to the others and motions for them to follow.

They all obediently follow him back through to the main room.

Nate and Robin whisper together as they walk, speculating about what might be about to happen. 

What looks like half the Justice League seems to have congregated in the main room. Some of them were there when the kids arrived, or came with them, but others have zeta-ed in while they were gone. 

Flash and Aquaman are there, as mentors to two of the team, but so are Black Canary, Red Tornado, Hawkman, and Captain Marvel. Martian Manhunter is standing by the zeta tube, having clearly just arrived. 

The two Green Lanterns are flying around the ridiculously high ceiling, moving heavy objects into position. 

"This cave was the original secret sanctuary of the Justice League. We're calling it into service again to serve as your base of operations. Red Tornado volunteered to live here and be your supervisor. Black Canary's in charge of training. I will deploy you on missions."

"Real missions?"

Robin looks dubious, possibly from experience. 

Batman looks a little bit like he just swallowed a lemon.

"Yes," he allows, "but covert."

"The League'll still handle the obvious stuff," Flash adds.

"There's a reason we have these big targets on our chests." He taps his lightning bolt insignia with a self-deprecating grin. 

"But Cadmus proves the bad guys are getting smarter."

Aquaman looks about as happy as Batman with this state of affairs.

"Batman needs a team that can operate on the sly."

"The five of you will be that team."

"Cool!" is Nate's verdict.

"...wait, five?" There are only four of them - Rain, Aqualad, Robin and Kid Flash.

"Is Yvette gonna be joining us?" 

"Not currently. Joining you will be Martian Manhunter's niece, Miss Martian." He motions behind them.

A smaller figure who has been hiding behind Martian Manhunter now steps out from the safety of his shadow. 

Like her uncle, she is green-skinned, and dressed in a costume with a red X over the chest. She also seems to have copied the high-collared blue cloak, although the costume under it is blue and white, rather than black. The most obvious difference between them, though, is her long, curly ginger hair. 

Other than the green, she looks exactly like a human sixteen-year-old.

She smiles shyly at her new team. 

"Liking this gig more every minute," Nate mutters to Robin.

He steps forward to greet Miss Martian, grinning broadly.

"Welcome aboard, Miss M! I'm Kid Flash, but you can call me Nate."
