J'onn walked in the next morning to find Alex in her lab, analyzing the green substance from the day before. He spoke gently, so as not to startle her.

"Have you found anything yet? Any matches to elements in our database?"

Alex looked up, eyes bloodshot and shoulders slumped. "It says it matched with something called Kryptonite, but I haven't gotten a thorough analysis yet."

J'onn's face fell, confirming his suspicions about the Kryptonite. Knowing it was used against Kara made his heart ache, both for her and for Alex. He sadly looked at her, and attempted to convince her to rest.

"Alex, why don't you take a quick nap or something? Just to get a little rest. After you come back, I can go over it all in detail with you."

Alex immediately straightened up. "I appreciate your concern, J'onn, but that won't be necessary. You and I both know that I'm not resting until we find her. Until we find something. This and the flash drive have been our first solid clues in five years. We almost had her yesterday. I've never been this close, and I can't let anything more happen to her."

J'onn realized his attempts were going to be fruitless, and instead directed his attention to the flash drive Alex had mentioned.

"Have you looked at the drive yet? There could be something in there."

Alex shook her head miserably,"Haven't had time. I've been in here all night trying to get something definitive from this sample."

Hank suggested,"While we wait for your analysis to finish, we can examine the drive's contents. It might have some hints or information for us. Then once we finish, I'll fill in any gaps about the Kryptonite."

Alex nods, standing. "I guess I could use a little break from that. I'm starting to see green everywhere I look."

With that, J'onn chuckled and grabbed the flash drive off of her desk. He brought her to a private viewing room, in case the contents were... unsuitable, as he suspected they would be.

He also didn't want the rest of the agents to see how this would impact Agent Danvers, if the videos turned out to be... difficult to watch.

Alex and J'onn took a seat and loaded the first video.

They watched a tall older blonde, introduced as Lillian Luthor, enter the room they were just in the day before. Alex instantly recognized Kara in the back cell when the camera panned over.

Her heart sank, knowing what was coming next.

As she watched her little sister get sliced and stabbed by the Kryptonite knife, she felt like throwing up. She also felt her eyes welling up with tears.

They continued through every single one of the videos, until they were all over.

Alex had to watch her sweet and innocent baby sister get electrocuted, injected, and suffocated, among many other things.

She stood abruptly, her tears having stopped after the third video.

They were instead replaced by a swelling rage and uncontainable anger.

In the beginning, she felt horrified. Like she was living her worst nightmare.

Which she was.

Now, she just felt plainly and simply, pissed off. And J'onn knew it.

"Alex, I know that was horrible, to put it lightly. But you can't go doing anything reckless or dangerous. We now have clues to work with, and an in depth character study of this Lillian Luthor. We finally have something to act on, and can not blow this opportunity."

Alex calmed slightly, but her anger was still threatening to boil over. "J'onn, Lillian needs to pay for all of the torture she has put Kara through. It's been five years of relentlessly hurting her, and she's going to die for it. Kara is only seventeen. Nobody should have to go through this, but her whole life has been ruined by this Lillian." She spat her name venomously. "J'onn, as soon as I get my hands on her, she is going to die a slow and painfu-"

"Alex. STOP."

J'onn understood what kind of pain Alex was going through, better than anyone. It had happened with his wife and daughters.

But somehow, the pain seemed amplified, having to watch someone else go through it. Having to watch the pain destroy someone he had grown to love as his own daughter.

"Alex, please. I know it hurts. And I know that right now, you feel like killing pretty much everyone in Cadmus. But this crazed violence and aggression is not going to get you anywhere. You should know that Kara is still waiting for you. Hoping for you to come."

Alex stared at him, winding down a little. "How do you know? Have you talked to her? You couldn't possibly know that she still thinks I'm coming." Alex was on the verge of tears.

"I know because we had a video every month of her. And every time, she pulled out the picture. Until those videos from the last year, when Lillian had taken it. But she still reached into her pocket, hoping it would be there. Knowing that you were still searching. She still has faith in you, and I know it for sure because of that bond you share. You'd never lose faith in her, so you need to believe that your sister has as much faith, or maybe even more, in you."

Alex seemed almost devoid of anger and uncontrollable violence at this point, and was having difficulty saying anything.

Her emotions had finally overwhelmed her.

She collapsed into J'onn giving him a tight hug. She whispered to him.

"Thank you, J'onn. I really needed to hear that. If Jeremiah was here, he'd be glad that you have become like a father to me."

J'onn felt his own eyes tear up, returning the hug with extra strength.

"I'll always be here for you. Both. When we get Kara back, I'll be here for her too. You both are my girls now, whether you like it or not." Alex nodded, feeling reassured. Her body was too exhausted from emotional overload to get any words out.

J'onn continued,"You get some rest, and when you're ready, we'll work on getting our girl back." When he got no response, he looked at Alex, noticing that she had fallen asleep in their embrace.

He gently lifted her off to a DEO bunk in an adjacent room, and left her to sleep.

Then he gathered all of the agents in the control room, and prepared for a long briefing.
