There is no further doubt in Kara's mind that Lena is alive now. She hasn't dreamed that smell. Still in her Supergirl outfit, she requests access to the building's surveillance system. The man who leads her to the room is grumpy and grumbles about the FBI making a mess of his place and Kara simply tunes him out after thirty seconds.

She sits in the uncomfortable chair and watches the monitors closely. She rewinds the surveillance feed to about a day earlier and decides to focus on the entrance of the building, and on the hallway that leads to the penthouse. There's no way Lena made it to her place by using the roof unless she's become a ninja or something and climbed the building. So Kara sits and waits.

It's over four hours and seventeen minutes later when she jumps out of the chair and hits pause, then rewind.

"What the…"

The time on the monitor indicates 8.36.13 in the morning—this morning. Except that it remains stuck on 13 seconds for three more seconds before it jumps up to 8.36.14. Kara rewinds the feed over and over again, trying to make sense of what she's seeing. Because time froze for three seconds but there's absolutely nothing out of the ordinary on screen. There's no one.

At 9.07.54, time freezes again, for three seconds, again. In and out, Kara thinks. Yet the monitor shows nothing but an empty hallway and a closed door.

But Kara can feel it in her bones. Lena was here today.

The search for the other woman is going to drive her insane. Kara doesn't know where to look, where to even begin. She can't ask Alex or anyone else because they'd think she truly lost it. There is one thing she can think of, so she flies to the DEO and hopes that Winn is working late hours again.

When she sees him at his usual desk, she sighs in relief.

"Winn!"

He turns in his chair.

"Supergirl? What are you doing here?"

"I need you to do something for me."

"Uh, is it illegal?"

"No! As if you'd care if it was, anyway."

Winn shrugs and smiles. He's never been worried about doing illegal stuff, especially now that he does it on behalf of a secret organization.

"So, what is it?"

"I'd like to see the video surveillance of L-Corp the day of the attack."

"Uh, why?"

"Just show it to me, Winn. Is there anywhere I could be alone to do that?"

He looks at her suspiciously but Kara doesn't waver.

"There's a room I can set you up in. But, Kara, I don't know what you expect to find on these old feeds. We went over them already."

"That's none of your concern, Winn. Just, please, do as I ask?"

She loves Winn, truly. He's probably her best friend still, despite James and Mon-El. It doesn't feel right to compare him to Lena. Lena is… she's different. Their friendship is different. But Winn, dear Winn wants to help, always. And so he doesn't argue further and after a couple of minutes he spends typing on his keyboard, he stands up and leads Kara to a room she's never been in before. There, he gives her a laptop and types a few codes that Kara doesn't bother to try and understand.

"There you go," he says. "The day of the attack. Have fun. Don't stay up too late."

"Thanks, Winn."

"Anytime."

And then Kara is alone.

She finds what she's looking for rather quickly. At 7.57a.m, Lena's car pulls up in the parking lot, in the reserved spot for the CEO. Kara's breath catches in her throat when she sees the other woman exit her vehicle. Lena had been wearing a dark blue dress that day. Kara didn't know that. Seeing her now, alive on that screen, makes her stomach churn. Her right hand grips the table so hard it leaves a dent in the metallic surface.

Kara watches as Lena walks toward the elevator and disappears in it at 7.59. She knows that the DEO doesn't have the feeds of Lena's floor because the explosion blew everything up. She calculates roughly the time needed to go up from the parking lot to Lena's office. The CEO had ample time to make it before the bomb went off.

There is no way she could have survived the explosion. If she'd been on another floor, someone would have seen her and told the police about it. Kara lets her head fall into her hands. Then, with renewed confidence in what she felt earlier in Lena's penthouse, she focuses on the screen once more.

At 8.21, the doors to the elevator open and no one comes out.

"Rao," Kara whispers. "It was you."

If life on Earth as an alien has taught Kara anything, it's that the impossible doesn't exist. Her own powers are proof enough. Sure, she's not technically human, but humans have managed a number of things their ancestors never thought could be achieved.

So, if Lena has found a way to escape an explosion and to manipulate camera feeds… well, it's possible, isn't it? Because what other explanation could there be? Hell, she wouldn't be surprised to find out that the Luthors are, in fact, immortal. Well, if it wasn't for the fact that Lex kept trying to kill his sister.

Kara paces in the small room, laptop still showing the elevator doors open and close, on a loop. Why did the DEO overlook that detail? She rushes out of the room and makes her way back to Winn, who is still at his desk. He looks up when he hears her approach.

"Hey, found what you were looking for?"

"I need you to come with me. There's something you can clear up for me," she says hurriedly.

"Uh, okay," Winn replies hesitantly as he gets up.

Supergirl grabs his arm and speeds back to the room. Winn looks pale when she lets him go, and he stands shakily on his feet.

"What's the rush, Kara?"

"Look," she orders and she points to the laptop.

Winn turns his eyes to the screen and watches intently. After a minute, he looks up at Kara.

"I don't get it. What am I supposed to see?"

"Winn, the elevator doors open and close, but do you see anyone in or out of it?"

"No, but that could easily be explained by a technical malfunction."

"It's not. I've checked all the feeds. The elevators stopped working after the explosion. All of them, but not this one. This one opened once more."

"So why did you ask me here?"

"I just needed to check that it wasn't just me who couldn't see anything. That it wasn't because I'm an alien."

"Well, it's not. But I really think you're reading too much into this."

Kara doesn't bother to reply. She thanks him and hands him the laptop before sending him off. There's not much else she can do here, and when J'onn crosses her path a moment later and asks her to stay at the DEO because they might have a rogue alien in town, she accepts reluctantly.

A fight with someone as strong as you is both entertaining and very annoying. Kara has learned that the hard way in the past but tonight she wishes she could just beat the alien's ass and go home. She's in no mood to fight but the Guardian and Mon-El can't do her job for her, so Supergirl endures punch after punch and gives back as good as she gets.

It still takes the help of some DEO agents to bring him down and restrain him. The alien roars and vows that he will free himself until Alex gets bored with his yelling and jams a needle in his neck. In less than five seconds, he is out.

"There," she says, "take a nap."

Alex walks over to where Supergirl is standing.

"Hey. That was quite the fight! Are you alright?"

"Yeah. Yeah I'm okay. I'm just going to… go home and sleep."

"Okay…"

Her sister looks concerned but Kara offers her best reassuring smile before she shoots up into the sky and disappears from Alex's sight.

The hot shower does wonders for her slightly aching muscles. Kara takes her time to wash her hair, and once she's done with her shower, she decides to try the new body lotion Alex gifted her earlier this week. It smells like coconut and she finds that she enjoys it very much. It makes her skin perfectly smooth.

She puts on a clean shirt and underwear, and slips into her most comfortable pair of sweatpants before heading to the kitchen. She hasn't eaten in far too long and her stomach is reminding her of that rather loudly. In the fridge, Kara finds leftover lasagna and she uses her heat vision to warm it up quickly.

She's about halfway through her plate when there's a knock on the door. A quick glance at the clock on the wall tells Kara that it's past midnight and she sighs because only Alex would dare to come over so late. As she gets up from her stool, Kara takes a sip of her water, sets the glass down and hurries toward the door.

To her surprise, when she opens it, it's to an empty hallway. It takes her a second to realize what is going on. Slowly, she takes a step back and waits. Nothing happens, and when she tries to use her x-ray vision discreetly, Kara sees nothing suspect at all. She sighs and closes the door and locks it.

And then she smells it.

The perfume.

Lena's perfume.

Lena is in her apartment.
