Leo smiled as Kara opened the door to her apartment. "Leo."

"Kara… I brought wine. I hope that's ok." He said as he entered and Kara took the wine bottle from him.

"That's perfect. I ordered Chinese food, hopefully it doesn't take too long to get here." She set the bottle down on the counter while Leo removed his coat and hung it up on the coat rack. This was their first official date. It was Kara's suggestion they have a movie night. "Humm I can't believe you've never seen The Wizard of Oz, it's a classic."

Leo smiled. "Well it's a good thing I have you to introduce me to it."

"You've definitely have been missing out on musicals. Don't worry I can fix that. Oh, we need to watch Funny Face too! It's so romantic, it's got Fred Astaire and Audrey Hepburn. By the time I'm done with you, you'll be a musical nut." She grinned. Leo was wearing a suit yet again, did the man not own any normal clothes? Well he didn't have a tie on this time, Kara couldn't complain too much he did always look handsome in a suit. There was a knock on the door. "Oh the food must be here!" She quickly shuffled to the door and got the Chinese food from the delivery man.

Leo decided on opening the wine he brought. After finding some glasses he poured some for them both while Kara set up the food near the television and got the movie ready. Leo handed Kara one glass of wine and then sat next to her on the couch before he removed his suit jacket and set it over the arm of the couch. Kara seemed excited for Leo to see this movie for the first time. Kara had given this movie so much praise that Leo had been curious. Movie nights with the family was not a Luthor tradition.

By the end of the movie Leo was leaned back against the couch his hand holding Kara's hand her fingers laced between his. He was stuffed by the end of the movie and they ended up finishing the wine. "So what'd you think?"

Leo smiled. "Humm I liked it. I can see why you like it, and it had a happy ending too. She got home to her family and the people that she loved. Home is the people you love." Kara reached for the remote and turned off the TV. "Kara, you've been eyeing that last potsticker for the last 5 minutes, please eat it."

"I have not… been eyeing it for that long." Kara gave a sheepish look before gently swatting Leo's arm. Leo knew how much Kara loved potstickers and how much the girl could eat. She did however pop the last potsticker in her mouth.

"I'm stuffed." He let out a sigh. "Happy?"

"Very. I'm also very stuffed as well." Leo smiled before he leaned forward then and slowly kissed Kara, he felt Kara return the kiss. It had been a long time since he'd let himself feel like this with someone. He had a connection with Kara he couldn't deny. As they broke the kiss he felt Kara's fingers gently caressed his cheek.

Leo's cell rang and as he looked at the caller id he saw Kara's name. He answered it. "Hey, Kara."

"Leo, I've been trying to reach you for a few days now." Kara was obliviously concerned, and part of her wondered if it had something to do with their relationship.

"I know, I'm sorry I haven't gotten back to you. I've been swamped at L-Corp. I didn't realize how massive the workload would be." He sighed then. "I also have an employee that's come to me for help with a very serious problem."

"Oh no, is there anything I can do?"

"No, it's something I need to keep quiet for now. I appreciate the concern. Don't worry about anything, everything's fine. I really should get going, I'll call you later Kara." Leo gave a small smile before he hung up the phone. He walked into the elevator and took it down to one of the labs in L-Corp. Once he came down he saw Sam sitting on the medical bed. He'd taken her down into an isolated lab and was doing his best to help her. Still she didn't believe him, didn't believe she was Reign. He'd have to do something more drastic. Leo loved Sam like a sister, he'd do anything to help her.

Sam stood up as she saw Leo and walked toward the force field. "I just wanna go home, Leo please? Please let me out of here." She begged.

"I want to get you home to your daughter as much as you do. Believe me. I am just trying to protect you. Both of you." Leo walked over toward the one desk and grabbed a tablet.

"I told you this before, if I had hurt people, I would remember."

Leo gave a nod. "You're right. You would remember." He walked back over the tablet in his hand. "On some deep level, you would feel what you had done." He pressed a few buttons bringing up an image on the TV screen in Sam's cell. "When you look at this, do you remember what it was like? Attacking Morgan Edge?" Brining up various images of the news about Reign. "No? No recollection?" His finger flipped to the next one featuring Supergirl and Reign. "Supergirl? I mean, that's a difficult one to forget. Having your fist connect with something so solid, so powerful."

Sam shook her head. "This is insane!"

Leo pressed. "How did it feel to obliterate? You tore those men apart. You ripped the limbs from their body and you dragged them across the beach!"

Sam's eyes were wet and she yelled at Leo. She couldn't understand why he was so hell bent on this ridiculous notion she was Reign. "Why are you doing this! Why! I just wanna go home to my daughter!"

"Like I'd let someone like you near Ruby."

Sam growled. "How dare you."

The growl was a step in the right direction. He knew how much Sam cared for Ruby and if this was the only way to bring Reign out then he'd have to. "What did it feel like? Living in that house, day in, day out, pretending to be her mother? Watching her sleep, so vulnerable. Knowing that any minute you could rip her apart with your bare hands. You're not a mother, you're a monster. And I will make sure you NEVER see Ruby again."

"Enough!" Sam yelled as her eyes turned red and Sam shot heat beams from her eyes. She yelled and began to toss any object not bolted down in the room. Leo quickly pressed the button on the tablet he had injecting Sam with Kryptonite, from the device he had implanted into her. She soon collapsed onto the ground. It had worked, he sighed. "I'm sorry Sam."

When Sam awoke Leo had the recording of her playing and as Sam saw it she began to cry and shout. Seeing herself lash out on the screen, she was a completely different person. "No! Oh, my god! Stop! Stop! No, make it stop!" Franticly she began to hit any buttons on the keyboard trying to desperately make it stop.

Leo turned off the feed. "I needed you to see it for yourself."

Sam was sitting on the ground holding her knees to her chest. "All those people…" She sobbed tears running down her face.

Leo shut off the force field and sat down next to Sam. "It wasn't your fault. You weren't in control. When you transformed, I was finally able to get some data on Reign's DNA, okay? We have knowledge now, and knowledge is power." He pulled Sam close hugging her and she desperately hugged him tightly crying into his shirt. "We're gonna get you through this. It's okay. I promise you, Sam."

Sam eventually calmed down, "I need to call Ruby." Leo handed Sam his phone and she began to call the number. Her fingers shaking as she dialed.

"They're coming."

Leo stood up. "Who's coming Sam?" Before she could answer Supergirl, Mon-El, a brunette woman Leo had never seen or met before, and J'onn J'onzz appeared in his lab. Supergirl was frantic as she saw Leo "Leo! Leo, the Worldkillers are coming. We have to get you somewhere…" Supergirl paused as she actually took notice of her surroundings. "safe…" She saw Sam, and as she came closer to Sam her fingers reached out and touched a force field. "What is this?" Her head snapped to Leo for answers.

"I was going to tell you."

"Tell me what?"

"About me." Sam stood up and took the wires off the temples on her head.

"Sam?" Supergirl seemed confused and rightly so, no one suspected Sam and Regin to be one in the same. The next thing Leo knew was the other two Worldkillers burst into the room. Leo felt a shockwave knock him back. Reign emerged, "Finally!" She began to rise floating up into the air. "El-may-arah." With a bright light the Worldkillers were gone and there was nothing they could do to stop them.

Leo found himself sitting in the D.E.O surrounded by people who looked at him like he was just another Lex Luthor. J'onn began after they had started recording. "Please state your name."

"Leo Tiberius Luthor. Where should I begin?"

Supergirl asked. "How long has this been going on?" Her arms remained crossed over her chest.

"Three weeks."

"And what exactly have you been doing with Sam for weeks?" Kara couldn't help but remember the employee that he had been helping. He had alluded to something but Kara never expected this.

"When I first suspected that Sam was more than she knew, I took her to a secret lab in L-Corp, where I conducted a series of tests. With her consent."

"When I examined her, I found nothing out of the ordinary." Alex stated.

"Then you weren't looking for the right things." Alex had looked for a more normal condition, while Leo had suspected that something out of the ordinary was wrong with Sam.

"So what did you find?" Alex asked.

"After sequencing her DNA, and comparing Sam's blackouts to Reign's attacks, I came to the conclusion that Sam and Reign were one and the same. Sam is Reign."

"So, for three weeks, you've been harboring and abetting a mass murderer." J'onn accused.

"I helped a friend."

"And you didn't think to bring this to our attention?" The Director questioned.

Leo crossed his arms. Oh, yes because getting the government involved would have made much more sense. They would have either killed her or locked her up. Why would he trust the D.E.O? "The attention of a clandestine organization, that has never formally acknowledged its existence to me? No. I'm not your employee. I've not signed a contract, nor sworn an oath. I conducted an L-Corp experiment, using L-Corp technology on L-Corp property."

Supergirl sighed. "What did you discover?"

"I was hoping to isolate the spark that turned Sam into Reign, but I didn't get a chance to finish." He'd failed to help Sam and now things were even more of mess. Sam was with those other women, Worldkillers Supergirl called them.

"Weeks with Reign." Supergirl looked down she couldn't believe Leo hadn't told her about this. The man she cared about kept this a secret for so long. Her eyes lifted up and she stared straight at Leo. "Do you have any way of tracking the Worldkillers?"

"No."

"Anyone else?" Supergirl looked around the room.

Mon-El shook his head. "They've gone to ground. They're not coming up again until they have something big to do."

Imra sighed. "The future's fate is more precarious than ever."

Brainy raised his eyebrows. "Would you like to know our odds of defeating pestilence at this juncture?"

"No." Mon-El and Imra firmly said in unison.

Kara wondered how Leo was able to control Reign, she was extremely powerful. Had he used some technology to control her. "How…how did you keep her contained?"

Leo cleared his throat before slowly looking at Supergirl. "Lex kept a vault in the lab. When I took over L-Corp, I inherited all of its assets, for good or for ill. I used Kryptonite."

Leo saw the looks everyone gave him. Like he'd done something awful. He knew what they were thinking, they didn't have to say it. He was a Luthor, Luthor's were always evil and apparently this proved that much. He was allowed out of that interrogation room and stood out on the balcony. His hand pulled out his cell and after a few buttons pressed, his thumb hovered over Kara's number. What if she didn't understand? What if he had screwed things up already? His thumb pressed down dialing Kara's number but it had gone right to voicemail. "Hey… Kara its Leo. Call me back as soon as you can. I just… I just really need to talk to you."

"Leo!" Supergirl called. He hung up the phone and turned his hands shoved in his pockets.

She was disappointed, it was easy to tell. She placed her hands on her hips and she shook her head. "I've had your back so many times. When the rest of the world was ready to pass you off as the new Lex Luthor."

"My friend came to me. She was alone and afraid. I had to do something."

Supergirl crossed her arms her eyes narrowed slightly. "I need you to level with me. Do you have any more kryptonite?"

"No, it's all gone. I used the last of it to keep Sam sedate…" Leo noticed Supergirl's eyes focusing on something in the sky he turned following her gaze. An… eclipse, that wasn't possible. Supergirl held the side of her head groaning slightly as if in pain. "Supergirl? Are you alright?" The woman soon began to fall to the ground and Leo caught her before she fell and set her down gently on the ground. "Hey! Someone get help!"

Alex was the first to arrive on the scene. "What happened?" She knelt down next to Supergirl.

Leo shook his head. "I don't know she collapsed."

A moment later Supergirl awoke with a start gasping. Kara's eyes resting upon her sister. "Hey, it's alright! What happened?"

"I saw Sam."

Alex looked at her sister she could tell she was holding all of her emotions in at the moment. "Are you sure about this?"

Kara shook her head. "No, but Leo's right he's been working with Sam for weeks."

"Are you okay?"

Kara took in a deep breath. "No… Lex has been imprisoned for years, but he held onto kryptonite anyways. Kryptonite, Alex!" Had she made a mistake with Leo? "Lex, could have only had it for one reason."

"To kill Superman." Alex gently took Kara's hand. "Look I know how difficult this must be for you and I know how much pain kryptonite can cause you. You've told me before that Leo isn't Lex."

"I know… but what if I was wrong. The Leo I've known up till now has been the sweetest boyfriend. I want to believe him, but he lied about Sam." Kara's eyes welled up with some tears. "I have to know the truth."

"Kara…what are you going to?"

Kara bit her lip before saying. "I'm going to ask James to break into Leo's lab."

Turned out Leo didn't have any kryptonite in the vault, he was telling the truth. Of course the Worldkiller's fortress was gone as if nothing was there. They hadn't saved Sam either, she looked at her phone and called Leo. "Leo, I got your message is everything okay?"

"Kara…. I just really needed to talk to you." Leo had felt guilty for keeping Kara in the dark about Sam. Now was the time to tell her the truth.

"What's wrong?"

"I owe you an apology."

"What for?"

"For ghosting you, for keeping secrets. But it's time to be honest." Leo wanted things to work out with Kara and he knew he had to open up to her. It wasn't something he was used to. All his previous relationships had ended badly. Why open up at all. Kara was different and she deserved to be told the truth.

"About?" Kara felt guilty, why had she asked James to break into Leo's vault. She should have trusted him. She shouldn't have asked James to do that.

"Sam Arias is Reign. Supergirl knows, and so do the appropriate authorities."

"What?"

"I was working to rid Sam of Reign, to free her."

"How did you keep her under control? She put Supergirl in a coma."

"The last of Lex's kryptonite. And don't worry, Supergirl knows about that, too."

The fact that Leo was telling all of this to Kara only made her feel worse. Leo trusted Kara he didn't trust Supergirl, which was why he kept it a secret. "Why are you telling me this now?"

"I gambled everything. My reputation, Supergirl's trust in me, and my relationship with you, on fixing Sam. And I failed, Kara. I thought I could help her but I might have ended up making things worse. I didn't want you to look at me like I was a Luthor."

"Leo, I'm not going anywhere. You still have me and I will always be with you. No, matter who you are you are my boyfriend and I-I love you."

"I love you too Kara."
