This oneshot used to live in the main story, as penance for a long hiatus without word after my laptop betrayed my trust and a fan inside it exploded.

"How is this in any shape or form considered fair?" Instead of keeping up any kind of stoic pretense, Kid Flash sat down on the ground.

Black Canary gave him a pointed look from the sidelines, but she was ignored.

"It's not supposed to be fair, moron." Robin smacked his friend lightly upside the head as a form of admonishment. "That's the whole point of the exercise!"

"Look, I'm pretty sure there isn't a single person in this room hasn't dealt with some kind of evil duplicate situation! I mean, Superboy is literally-"

A low growl from the boy in question cut off the speedster before he said something he would most definitely regret. Instead of attempting to salvage the situation, he just gestured wordlessly to the source of his distress

Hawkgirls

As in the plural.

Standing across from the gathered members of the Team were two Thanagarians. Only one of them had a mace, but that distinction did nothing to clarify the identity of the real Ski'Lira Hol. They already knew the imposter was M'Gann, who was taking full advantage of her shapeshifting and the use of a direct mental bond between herself and Sky.

Needless to say, they weren't making it easy.

"I still think that Hawkgirls Two is the real one." Artemis had her arms crossed and eyes narrowed in concentration. "I still can't see her giving M'Gann her mace, even if it is for a training exercise."

"Unless it's a double bluff? Or a triple bluff?" Zatanna chewed on her lip. "This would be so much easier if I could use magic."

"Zee might have the right idea..." Robin pondered. "Maybe it's a fake out. She knows that we know she wouldn't give M'Gann the mace, so she gave it to her on purpose, making her Hawkgirl A."

"Perhaps she predicted we would guess as such?" Aqualad offered, somewhat unhelpfully, as his contribution only confused them more.

"But she could have predicted that too." Making a frustrated noise, Zatanna shook her head. "Ugh... It's just like the Princess Bride."

"She likes that movie." Superboy said, but was quickly ignored as it had no relevance to the current situation.

Aqualad seemed to have developed a different strategy after his last suggestion was shot down "We could try answering questions again?"

"The mental link makes that moot." Artemis reminded.

"I was referring to their... Delivery in answers. Both Skylar and M'Gann have distinct personalities. Even with one feeding the other the correct answers, they would provide them differently."

Artemis snapped her fingers, a grin appearing on her face. "I got it. Hawkgirls?"

"Yes?" They answered in unison as they crossed their arms in tandem, making Wally visibly shudder.

"Wally was the one who tore your Ocarina of Time poster."

Hawkgirl A immediately whipped her head towards him, far too quickly for Hawkgirl B to mimic in time. "It was you?!" Hawkgirl B seemed to resolve herself to her failure, opting to maintain a neutral expression as the other fumed.

"Found her." Robin needlessly gestured to Hawkgirl A.

Clearing her throat to garner their attention, Black Canary stepped up from where she's been quietly watching the proceedings. "Is that your final answer?"

There was a slew of agreements.

"Well, Skylar? Were they right?"

"Not even close." The Team whirled towards Superboy in shock, as he stood there with an uncharacteristically shark-like smirk on his face. Like water thrown at a still drying painting, his form dripped away as the magical illusion dropped (courtesy of a borrowed spell), revealing a still grinning Skylar.

A quick glance behind them confirmed the presence of M'Gann, but next to her was J'onn J'onnz, who carefully held Sky's mace. He hastily returned it to her.

Meanwhile, Wally was making a noise like an owl being stepped on as Artemis pumped her fist in the air in semi-victory. "I knew she'd never let M'Gann use her mace!"

Robin smacked himself in the head as he shared an anguished look with Zatanna. "It was just like the Princess Bride. She even gave us a hint. Bats is never gonna let me hear the end of this one."

"So you could say..." Skylar began.

Shooting up from the floor, Wally interrupted her. "Don't."

She was not to be deterred. "Inconceivable?'

Long story short, Skylar ended up laughing her ass off as the entirety of the Team (including a hastily recruited Miss Martian) around the entirety of the mountain. And if they all say down later that evening to watch Princess Bride, well, that was nobody's business but theirs.
