After relocating to Argus, Team Arrow continued working to find their missing people when another agent approached Lyla.

"Agent Michaels, we have visitors." the agent said.

"Now is not a good time." Lyla said.

"Ma'am, it's Director J'onzz and he's brought Supergirl with him." the agent said and now Lyla was panicking.

"Bring them in here immediately." Lyla said, not seeing Oliver's relieved look that Supergirl was here, since he knew that Kara would speed up their search and be a big help if who he thought was responsible was involved.

A few minutes later, J'onn and Supergirl joined them.

"That's Supergirl." Thea said, freaking out.

"Nice to meet you." Oliver said, holding out his hand to Kara, who thankfully understood his meaning and shook his hand.

"You to. Since I can take a guess that you're the Green Arrow, I might as well tell you my identity, especially since Sara Lance already knows." Kara said.

"Really how would she know?" Laurel asked.

"Because she's dating my sister." Kara said.

"Wait, you're director Danvers' sister?" Lyla asked.

"Adoptive sister and yes. You can call me Kara." Kara said.

"We know Supergirl's real name." Thea fangirled and Oliver rolled his eyes.

"What's the status on the search for Director Danvers?" J'onn asked, getting them back on topic.

"No luck so far. Whoever did this did their research. They disabled Alex's subdermal tracker and we can't get her or Sara on satellite." Lyla said.

"Subdermal tracker?" John asked.

"All agents of the DEO and Argus have trackers in their bodies for exactly this purpose. Don't worry, they are aware of it." Lyla explained and J'onn nodded.

"Okay then. Any other ideas?" J'onn asked.

"I'll find them." Kara said.

"And how do you plan to do that?" John asked.

"My super hearing. I can use it to listen specifically for Alex or Sara's voices and locate them that way." Kara said.

"You think that'll work?" Laurel asked.

"Something tells me their captors didn't know that Alex's sister is Supergirl. My comms are connected to J'onn's. When I find them, I'll give him their location so you can meet me there." Kara said and they all nodded as she flew out.

As Kara flew over Star City, she closed her eyes and focused her hearing on listening for Alex and Sara's voices.

She kept listening until finally, she heard Sara's voice shouting and screaming and she was able to locate her.

"J'onn, tell Argus that I've located Sara in a warehouse at 5th and Sabers." Kara said.

"Copy that. Go in and we'll meet you there." J'onn said.

"Got it." Supergirl said as she flew towards the warehouse and crashed right through the wall to see Sara in chains.

"What took you so long?" Sara asked as Kara quickly broke her chains.

"Very funny. Where's Alex?" Kara asked.

"She somewhere in here. Please tell me backup is on the way?" Sara asked.

"Green Arrow and his team, plus J'onn and Argus are on their way here now." Supergirl confirmed.

"Good. In the meantime, we need to find Alex." Sara said and Kara could tell that she was panicked.

"Let me see if I can find her." Kara said as she used her x ray vision on the building and quickly found Alex and she was pissed by what she saw.

"It looks like they've got her strapped to a table about to inject her with something." Kara said and now Sara was freaking out.

"Where is she?" Sara asked.

"Two floors up. I'm going in." Kara said as she flew through the ceiling and Sara only hoped that Kara made it in time.

Alex was currently trying to fight back against her captors as one of them that she recognized as Slade Wilson approached her.

"You should be more careful who you love Director Danvers. It may come back to bite you. Like now." Slade said as he pressed the needle in her arm and Alex felt something enter her body as it began spasming.

"I hope you survive Director I truly do. You are the one weapon that will destroy Sara Lance." Slade said, right as there was an explosion behind them and to Slade's surprise, Supergirl charged into the room, eyes blazing.

"What?" Slade asked.

"Get away from her." Supergirl said as she used her heat vision to send Slade flying back as she rushed towards Alex and yanked the restraints off her, but could tell that she'd been too late to stop Slade from injecting her and as badly as she wanted to make Slade suffer for this, her sister was the priority, luckily for Slade as she then flew off.

"Sir, what should we do?" one of Slade's soldiers asked.

"Fallback. We'll be outnumbered in moments and now we've lost the element of surprise." Slade said, knowing that Supergirl would be back soon and even with his enhanced strength, he wouldn't stand a chance against a fully powered Kryptonian.
