Lena looked around the room at the four men, none of whom she recognised. "Who's behind this?" she demanded.

"You might be boss at L-Corp," the bald man said, "But you don't make the calls here."

"Let Kara go," Lena said with gritted teeth.

"What part of 'you're not the boss here' don't you understand?" he bald man asked.

The creepy looking man, who was still standing too close to Lena, sniggered.

"If that man is going to continue to stand disgustingly close to me, can someone at least give him a mint," Lena said.

The man swung his arm and punched Lena in the side at the bottom of her ribs, knocking the air out of her. The bald man grabbed Lena's right arm to stop her from falling. "Hey!" he yelled at his colleague.

"Lena!" Kara cried.

"I'll teach her to talk to me like that," the creepy man said as Lena straightened up and blinked back tears.

"Sometimes the truth hurts," Lena said, catching Kara's eye. Perhaps it was a trick of the awful fluorescent light, but Lena was sure Kara's eyes weren't usually that green.

"You can have her later," the bald man said, "Swap places with Chip."

The man blew Lena a kiss and swapped places with a man with a patchy beard who had been standing beside Kara.

"Lena, please, I'm sorry. I'm so sorry, but you..."

"I deal with this shit all day," Lena said, trying to regulate her breathing. "I can take one more bastard who thinks he's better than me just because of what's between his legs."

"No, Lena, please just..." Kara said, wriggling to try and make herself more comfortable.

Lena looked at her. One of Kara's sleeves had ridden up, showing that the green lines of kryptonite poisoning went up her arms too. The ropes which tied her to the chair must have been soaked in it, and it appeared to be just enough to sap Kara's powers and leave her in an uncomfortable, but manageable amount of pain. "What the hell is this all about?" Lena asked, looking back a the bald man, "You let her go. Can't you see you're hurting her?"

"Lena, you don't have to protect me," Kara said softly.

"We know what she is," the bald man said.

"In that case," Lena said, drawing herself up to her full height, "If you know what she is and who I am, I suggest you let us both go right now before we - "

"Ugh, enough," the bald man said, rolling his eyes and pulling out his gun.

Lena recoiled.

"Take it," the man said, holding it to Lena.

"What? No."

"Take the fucking gun, Miss Luthor," the bald man said, pushing the handle against her chest.

"No," Lena repeated, taking another step back.

"Lena, take the gun," Kara said.

"Kara, whatever is going on here, you are clearly not in control of the situation, so you do not get to tell me what to do," Lena said.

"I'm sorry, Lena," Kara said. "I'm so sorry, I - "

The bald man grabbed Lena's hand and shoved the gun it in. "Shoot her," he commanded, nodding towards Kara.

"No!" Lena said, dropping the gun.

The bald man bent down, picked the weapon up and fired it into the ground.

BANG!

The bullet crashed into the floor an inch from Lena's foot. Lena squealed and jumped aside, being grabbed by Chip who stopped her from falling. Lena and Kara's eyes followed the mangled green bullet as it rolled across the floor.

"Next time I won't fucking miss," the bald man said, pulling Lena back into position and shoved the gun into her hands. "Point it at Supergirl."

Lena held the gun with shaking hands, her heart pounding in her chest. "I can't do it," she said, looking at Kara, "I can't shoot you."

"Lena, it's ok," Kara said softly.

"No it's not!" Lena snapped. "This is not ok, this is - "

"But I thought you wanted to hurt her?" the bald man said, "She hurt you, after all. And now you get your revenge. Justice. Vengeance. Whatever you want to call it."

Lena shook her head, emotions threatening to take over. "No. No, you - you shouldn't know... you shouldn't... This is enough. Let her go."

"Oh Miss Luthor, we all know that's not happening. Not yet, anyway," the bald man smirked.

Lena looked back at Kara, fighting back tears. "I don't want to hurt you. Not really, not like this. I - "

"Come on Lena," Kara said, her face hardening. "As if you haven't thought about this. Well, here you go, Lena. Here's your chance."

"W - what? Kara, no, I - "

"What, you're going to chicken out now?" Kara snapped. "Don't be so weak. It's pathetic. Stop shaking and fire the damned gun. Show a bit of courage. What would you family say if they saw you now? They'd be embarrassed you hadn't pulled the trigger yet. Look at you, in ripped stockings and no shoes. Where are your shoes, Lena? Pathetic."

Lena closed her eyes and shook her head. "You don't mean that."

"Don't I?" Kara asked. "Why do you think I kept my identity secret? I knew I couldn't trust you. I knew you'd just go running back to your precious family. Though looking at you know, I don't think they'd want you either."

Lena glanced around the room, her eyes filled with tears. Their captors looked on awkwardly. "This - you don't..."

"You're so weak, Lena! You don't have the guts to do what you need to. Not really, not when it comes down to it. You're weak and pathetic and - "

"STOP IT!" Lena yelled, her hands shaking so much she could hardly hold the gun. "Kara, for god's sake, shut-up! You - I know what you're doing. You're riling me up. It's not going to work. You would never mean that. Not you. Not - I can't shoot you, Kara. I can't."

Kara sighed and shivered. Her face softened. "Worth a try," she said quietly, trying to catch Lena's eye.

"We finished with therapy time?" the bald man asked, "Now, shoot her and get one with it."

"No," Lena said.

"Lena," Kara sighed.

The bald man pulled out another gun from inside his jacket and jabbed it under Lena's shoulder-blade. Following his lead, the two men either side of Kara pulled out their weapons and pointed them at her, and Chip held his gun against Lena's hip.

"Now we're getting impatient. Even late-night Chinese take-away places have closing time," the bald man said.

Lena closed her eyes and wished herself away. She wished she'd stayed at the office, gone to the lab, gotten angry at herself as her thoughts drifted back to Kara. Kara, who was now only a couple of feet away, tied up with Kryptonite-laced rope. Lena racked her brain to try and find a way out.

"Lena, it's ok," Kara said gently.

Did Kara know something Lena didn't? Or was she just so damned calm to stop Lena from panicking? Was she still trying to save her, sacrifice herself so that Lena could get out? Lena opened her eyes, and saw the creepy man to Kara's left staring at her. He ran his tongue along his teeth, and Lena knew that either way, she wasn't getting out. Lena's eyes again met Kara's. Lena shook her head. "Kara, I am so sorry, but I - I just..."

"I know," Kara said. "I was wrong to keep things from you, and I am so sorry. But right now, Lena, I - I can't watch them hurt you. Please, I need you to trust me and - "

"No, Kara, I don't need to trust you. Not right now," Lena said getting a sudden spark of inspiration, and briefly glanced up at the ceiling before looking back at Kara. "But I need you to trust me and know that if nothing else, I do believe in Supergirl. That - I'll always do that."

"What?" Kara asked.

"I believe in Supergirl," Lena breathed, looking into Kara's eyes.

Kara gave a nod, "Take the shot, Lena. Do it now."

BANG!
