"It was her, Alex. I know what I saw."

Alex's gaze remains full of pity. Kara is pacing in front of her, replaying the earlier scene in her mind, over and over.

"Kara… Her office was blown up. No one on that floor could have survived the blast. You know that. I get that it's hard for you to accept, but it's been weeks now."

"You're not listening to me, Alex! I'm telling you she was there. I saw her with my own two eyes."

"For a fraction of second," her sister objects. "How do you know this was not just your mind playing tricks on you?"

"It didn't feel like that."

"How many hours of sleep have you had lately?"

Kara doesn't bother to answer. It's not like Alex doesn't know she hasn't been sleeping well. She stills and looks at her sister.

"You think I hallucinated her."

"I do," Alex admits as she steps closer to Kara.

Tentatively, she puts a hand on her shoulder and squeezes lightly.

"You need to rest, Kara. To make your peace with what happened. We'll find Lex. I promise."

At the mention of the Luthor's name, Kara's body tenses and she shrugs off Alex's hand and crosses the room to stand near the window. Alex sighs, defeated and unable to get through the wall Kara's built up around herself when it comes to anything Luthor-related.

"I need to go back to the DEO. Please get some sleep."

Kara lets her leave without another word.

That night, Kara lies awake, staring blankly at the ceiling. The events of the day replay in her mind. She sees Lena again, with her black hair partially hidden under the hood of a sweater Kara would have never imagined the CEO wearing. Her eyes, a shade darker than their usual vibrant green. The moment had been fleeting, gone as soon as it had come, but Kara is certain that it was real.

Only, when she'd made her way to where she'd spotted Lena, there was no trace of her. Kara had tried to use her x-ray vision to see through the walls of the buildings around, in vain. She'd tried to focus and listen to every sound in hopes of picking up something, anything that might sound like Lena but nothing had come of it. And yet, Kara knew she hadn't dreamed her.

Hours later, in bed, her opinion remains the same.

Lena is out there, somewhere, she thinks.

Sleep eludes her that night again.

Her step feels lighter the following days. She doesn't tell anyone else about Lena, she knows they will react the same way Alex did. They'll think that she's gone crazy, and Kara doesn't want to have to deal with that.

She spends her days at CatCo, working on her new articles that have to be ready for the next issue. She receives an email from Cat Grant that even manages to make her smile.

At night, Supergirl flies over the city, not as an asset to the DEO but as her own person. She looks for Lena in every building, canvassing the city block by block. She sees through walls, sees things she wishes she could forget. National City is big, and Supergirl wishes she could be lucky for once.

Luck, however, has other plans.

When the man that she hurt comes out of his coma and is cleared to leave, Supergirl is allowed back to the DEO. She doesn't apologize for almost killing him. Alex, with some well-placed threats, makes sure he won't be talking about what happened to him to anyone.

The man hasn't been gone for five minutes when Winn shoots up from his seat.

"Guys," he calls out, "you need to see this."

Kara rushes to his side, followed by Alex and J'onn.

"What are we looking at," J'onn asks.

"The surveillance feed of the prison where Lillian Luthor is held. This was just a few minutes ago."

Sure enough, the woman appears on screen in a room sparsely furnished. Her back to the camera, she leans over a table and appears to be writing something. Kara's heart starts to beat faster in anticipation. Finally, Lillian turns and holds up her piece of paper to the camera.

Supergirl.

That's all it says.

But Kara doesn't need more to understand the message. Lillian Luthor is requesting a meeting.

"You're not going alone," Alex declares, arms crossed.

She stands firmly in front of Kara, who is ready to fly to the penitentiary right away.

"She'll only talk to me; you know that," Kara points out.

"She's going to try to negotiate a deal."

"Lillian wouldn't be asking for me if she didn't have intel about Lex or Lena."

"Lena is—"

"Don't say it," Kara hisses.

"She'll get under your skin, Supergirl. And after what you did to the man I had to blackmail into silence only a few weeks ago, I'm not letting you go there alone. You'll need someone to reign you in if you lose your temper. She knows you were Lena's friend—"

"Are."

"—and she'll try to use that to taunt you. She's not above using Lena to hurt you."

Kara sighs, but she knows Alex is right. Lillian Luthor is evil and she has a plan of her own. Why she's taken so long to reach out is, in itself, a red flag.

"Fine. You're coming with me. But we're not driving there, so you better hold on tight."

Alex rolls her eyes but complies nonetheless. Kara's arms wrap around her sister and a second later, they're gone.
