Artemis and Zatanna were already late to the banquet, and their taxi driver was behind schedule. When he finally arrived and they got inside, they only made it about three blocks before he walked out in front of the taxi, causing it to swerve and crash into a lamppost.
"teG llA fO sU tuO fo ehT raC!" shouted Zatanna right before impact and all three of them appeared just behind the burning car, and the driver was already unconscious. Then the man stepped out from the wreckage and looked at the two of them.
"Dad?!" screamed Artemis.
"Hello, little girl." He said before shooting her with a tranq dart.
"Artemis!" screamed Zatanna, grabbing her and shaking her.
"Stay out of this, dyke. You're not a part of my plan." He said, shooting her as well, but taking Artemis and leaving Zatanna on the street. When she came to, there were ambulances everywhere, and she could see police blocking off Wally, Conner, Megan, Kaldur, and Donna. They were all very dressed up, and she assumed they all left the banquet to come see if she and Artemis were okay. They weren't. After she'd gotten proper medical attention, she cast a spell that made them all not pay attention as she walked away from the scene and to her friends.
"Zee, are you okay?!" asked Wally as she came over to them.
"I'm fine but Sportsmaster… he took Artemis."
"We have to get back to the Cave. Now." instructed Kaldur. As soon as they got back Kaldur pulled up a 3-Dimensional map of the world.
"Zatanna. Do you remember when the worlds were separated and you cast a spell to find Klarion's location?" he asked. Nervously, she nodded. "I want you to do the same thing for Artemis."
"O- okay…" she said, and just as she was about to try, Batman's face appeared on a screen in front of them. "Team, this is very last minute and I apologize for that, but it is absolutely dire. I've just gotten word from Aquaman that Ocean Master is leading a squadron of rogue Atlantean soldiers to the surface world through Happy Harbor. You are our first line of defense and I trust you will not fail. Batman out."
"Well, shit." Said Kid Flash. "What do we do?"
Recognized. Nightwing. B01.
"Kaldur, take M'Gann, Donna, Conner, and Wally and hold off the Atlantean army. Zatanna and I will find Artemis." He instructed, and for a second everyone just stared at him.
"Robin?" asked Kaldur.
"It's Nightwing now, but uh, yeah. I'm back, we can catch up later but right now you need to go."
"Right." Said Kaldur, and his team ran to the normal exit to get to the shore.
"Nightwing, huh?" asked Zatanna.
"You like it?"
"Yeah, I do."
"Alright, Kaldur had the right idea, our first step is gonna be you casting that location spell. I believe you can do it." He assured her. She took a deep breath and turned towards the model of Earth.
"wohS eM s'simetrA noitacoL!" she screamed as energy burst from her fingertips and collided with it, spinning the model around rapidly until it stopped at a point in Gotham City, zooming in to reveal the location.
"Artemis's old apartment?" said Zatanna in disbelief.
"Why would Sportsmaster take her there?" asked Nightwing.
"Let's go find out."
