Kara and Barry had just finished getting unpacked back at their home after returning from their honeymoon when Kara's phone rang.

"Hey, Alex, what's going on?" Kara asked.

"I know you just got back from your honeymoon, but I could really use Supergirl in National City and the Flash probably wouldn't hurt either." Alex said.

"We'll be there shortly." Kara said.

"Guess we better pick up our suits." Barry said.

"What was I gonna say, no?" Kara asked.

"Of course not." Barry said.

"Let's go." Kara said and Barry nodded as they both grabbed their rings, which were now reloaded with their suits, and then headed out of the balcony towards National City.

"Thanks for coming, I know you both have jobs back in Central City." Alex said.

"It's fine I needed to head to DC to talk to my dad about something anyways, but I can make this stop to. What's up?" Kara asked.

"Two things and I need each of you for one of them." Alex said.

"Okay and they are?" Barry asked.

"Flash, I could use you working with Sara and Wally to help track down recently kidnapped aliens and metas in the city." Alex said.

"I'm on it." Flash said as he sped out of the base.

"And what do you need me for?" Kara asked as Alex led her towards the monitors.

"This." Alex said, showing her what looked to be some sort of ship entering Earth's atmosphere.

"You want me to be the welcome wagon?" Kara asked.

"We need to know if these aliens are hostile." Alex said.

"I'm on it." Kara said as she flew out of the building towards the projected landing zone.

When Supergirl arrived at the landing site, she immediately sighed in relief when she saw it was a familiar ship landed.

"The Legion." Kara said as the Legion ship landed as she braced herself for who she knew was on the ship and how she'd likely have to reign in her husband and his jealousy.

"Whoever you are, identify yourself now. This will be your only warning." Supergirl said as the ship opened up.

"Relax, we come in peace as you say." a familiar voice said and Kara was surprised when she saw Querl Dox walk off the ship first, followed by Imra Ardeen and then, her breathing hitched a bit when she saw a face she'd never expected to see again.

"Supergirl, it's an honor to meet you." Mon-El said and Kara managed to control her emotions.

"Who are you?" Supergirl demanded.

"My name is Mon-El and I am the leader of the Legion of Superheroes from the 31st century." Mon-El said and Kara sighed.

"Okay, you three better come with me, since there are gonna be a lot of people who have questions for you." Supergirl said.

"And we will answer to the best of our abilities." Mon-El said and Kara nodded.

"Come with me. You can fly right?" Kara asked.

"Yeah, we can." Mon-El said as the rings they were wearing glowed and they lifted off into the air and the three legionnaires followed her, though Kara already had an idea of why they were here and she was honestly grateful for it, since it would make her plan easier to execute.
