"Team Arrow is here. Team Legends is here. Is that everyone?" said Felicity, trotting to the front of the hall.

"I think so?" replied H.R.

"Nate and Amaya are back watching the Waverider. The newbies," added Sara.

Oliver was anxiously awaiting the return of Barry. Thea chalked that interaction up to no more than Barry's social awkwardness and concern for his friends, but something was definitely up with this… Supergirl. A few more seconds passed before a breach opened up to the left of the hall. Simultaneously, Barry and Cisco jumped out with…

"Woah! That was cool," remarked Kara.

"Guys. Thanks for coming," shouted Barry as he walked towards everybody.

Kara quickly scanned the faces of everybody as she walked towards them. Almost everybody to her right was mildly surprised or fascinated, but the blonde woman at the center and the 3 on the other end all were… astounded. Staring in disbelief. The blonde woman turned her head to look to everyone on the right, almost as if it was out of concern. Silence echoed through the hall for a few seconds, before the handsome brown-haired man to her left spoke.

"Barry, I… thought… you said you were bringing us an alien," he said loudly. Kara couldn't quite pick up the tone in his voice. Slight irritation perhaps. Dumbfounded? Incredulousness?

"Yeah, we did. Everybody, this is my friend, Kara Danvers or, as she's known on her Earth, Supergirl," replied Barry.

"What makes her so super?" inquired the young black man on the right.

"Well…"

Kara immediately hovered above everyone. Just behind where the two groups were standing, she blasted her heat vision onto the concrete floor, creating the shape of the House of El symbol.

"I'm convinced," said the tall, dark-haired man to the right. She barely knew this guy, it was the first time she'd ever seen him, but for some reason, he reminded Kara of her cousin. Strange, she thought.

Yeah, no, maybe he and Thea hadn't seen everything just yet. Instead of being angry with Barry, Oliver actually decided to cut him some slack for this one. Telling your friend that a super-powered alien from a parallel universe is the doppelganger of the woman he loved who died three and a half years ago in his arms? That would be an extremely difficult task for anybody.

Oliver watched her as she greeted the Legends. Everything about her was the same. The smile, her voice, the laughter. He was doing his best to shun his emotions and stay focused on the mission, but he couldn't take his eyes off her. He watched intensely as she reached Sara.

"Kara, this is Sara Lance, The White Canary. Captain of the Legends," said Barry.

"Kara Danvers…" said Sara admiringly. The last time she saw Kara was before she got on The Gambit with Oliver. Well, her Kara anyway. Her Kara was much younger back then, the same age as Laurel. It was weird for Sara to be older than this Kara. Sara was taking this pretty well, but she was fairly concerned how Oliver was feeling.

"Yep that's me," replied Kara with a chuckle.

"It's really good to see you" she said, fighting the urge to pull Kara in for a hug and opting for a handshake instead.

"Have we met before?" asked Kara curiously, having picked up on Sara's tone. Sara didn't know how to reply, but she glanced at Barry, who simply shook his head subtly. He figured this probably wasn't the time to tell her that she had a deceased doppelganger on this Earth.

"Uhh, no. You just look like someone I used to know," replied Sara cheerfully. Kara smiled back at her before moving on to Team Arrow. Luckily with her Kryptonian memory and just generally being good with names, she'd only need one introduction to everybody.

"This is Team Arrow. This is Thea Queen, Speedy," said Barry

"Nice to meet you," said Kara as she extended her hand. She was startled when Thea ignored her hand and leapt forward with a hug, "Oh, ok then," said Kara nervously laughing, hugging Thea back.

"Sorry, it's just… really cool to see you," said Thea gleefully. As soon as she saw Kara pop through the breach, all of her memories of the night of The Undertaking came flooding back.

She was at CNRI with Laurel, helping Laurel pack up and salvage important case files. The earthquake device went off, trapping her and Laurel inside. Tommy helped Laurel escape, but was too exhausted to remove the debris from around Thea. That's when Kara arrived. Tommy was initially furious at Kara for being there, knowing what it would do to Oliver if something happened to her, but he needed the help, and together, they saved Thea's life.

Thea felt like she never had the chance to thank Kara for saving her life. Even though it's a different Kara, Thea still felt like she could finally do that, in some way.

"John Diggle, Spartan," said Diggle, introducing himself with a smile.

"Oliver Queen, the Green Arrow," said Oliver, putting on his best poker face while shaking Kara's hand.

As soon as Kara walked away, heading towards Felicity, H.R. and Caitlyn, Diggle tapped Oliver on the shoulder, and gestured with his head that they needed to talk. They took a few steps away from Thea before conversing.

"How are you holding up man?" asked Diggle

"I'm fine."

"You sure? I know I probably have no idea what you're feeling now, but coming face to face with an alien doppelganger of Kara can't be easy on you."

"Diggle, I'm fine. Really. You know more than anyone that the mission comes first. She clearly doesn't know. I'd like to keep it that way until this is over. Until then, she's just Supergirl to me."

"Ok." Usually, Diggle didn't like when Oliver shut out the human side of himself, but in this case, it was probably needed. Seeing Oliver like this did still trouble him. He felt like Prometheus was maybe starting to agitate Oliver more than he'd care to admit and the recent revelation that an alien invasion had begun was also unnerving. Still, things usually didn't work out too well when Oliver was like this.
