Author's Note: So this should've been up earlier, but I really wanted to do that Supergirl Oneshot I uploaded just before the finale. However, since I didn't want you all to wait any longer than I already had, here we are. This chapter actually wrote fast than I thought it would considering it's what is going to propel us to ward the end of the story. We're not there yet, but this is the turning point.

Please enjoy.

"No, no," Winn shook his head. "Siobhan, this isn't…she's still…," he stuttered toward the evil visage occupying Siobhan's body.

The Banshee shook her head as well. She then came off the wall and started to approach the glass. She smiled a mocking grin at Winn. "Uh…um…uh…no, yes," the Banshee began to say, poking fun at Winn's inability to choose his words. She then began to cackle at, what was to her at least, the delightfully broken look on Winn's face. "What's the matter Winnie? Can't figure out how to talk to me? Guess it's just like back at the office, huh? Except this time, there's no Siobhan to find you pathetically charming, because you're right – this isn't Siobhan. And yes, while she might still be in here," she said, forcefully tapping her temple, "I've got her buried so deep, I'm the only one that can hear her screaming."

Winn brought his hand to the glass. The Banshee brought hers up as well and placed it on the same spot as Winn's. "And she is screaming," the Banshee informed him, chuckling darkly.

This is all wrong, Winn thought. She was fighting – she was winning. But as he gazed at those pale, practically soulless eyes, he knew that this situation was far from fake. Oh God, he thought to himself. What's happening to Siobhan in there.

"What do you want?" Alex said sternly.

Without removing her hand, the Banshee turned and looked at Alex, her eyes travelling up and down her body. "Well, well, well; if it isn't the sister. Be right back, Winnie," the Banshee said slowly. She slid her hand across the glass as she moved over to stand in front of Alex.

"How's the little blonde moppet?"

"What do you want?" Alex repeated, slower and more deliberately.

"Not much of a talker this one, huh?" the Banshee asked Winn. "Guess when he was crushing on Kara it really was substance over style. Tell me, Winnie, is this one as good as Siobhan was? "

"Leave him alone," Alex said. "You're dealing with me right now."

"Ooh, feisty," the Banshee smiled. She looked over at Winn who had started to look like he was composing himself. "This one might be a keeper. You know what? I think I might do Siobhan a favor. She already can't stand the blonde Danvers, and seeing you, well it's the one time me and her are of one mind."

She turned back toward Alex. Her gaze was like some cold, remorseless predator. Winn could even swear he heard a growl come from her.

"She's gonna love watching me scream you two to death," the Banshee threatened.

"There is nothing going on between me and Alex," Winn told her.

"I don't care," the Banshee revealed. "Thanks to a little vision from me. Some insecurity from her. And we've got ourselves a recipe for fun. For me at least."

"Siobhan wouldn't let you," Winn spoke up.

"Siobhan is not in control," the Banshee replied. "I am. And believe me, part of her still wants to kill Kara. And just under the suspicion that you're going near her man, she'll have no problem letting me kill you," she explained.

Winn cleared his throat. He knew it was the wrong thing to do. It was a sign that he was trying to compose himself. A sign that she was getting to him. Alex remained stoic, ever the trained agent, used to dealing with hostiles threatening her.

"You can dream all you want about that. You are not getting out of here," Alex told her.

My, my, my, Winn sure does know how to pick them, the Banshee thought. "I wasn't supposed to be able to overpower that shock collar, but I channeled just enough of me into Siobhan to do it. I wasn't supposed to be able to crack that containment cell, but I did that. I wasn't supposed to be able to subdue Siobhan enough to be here, yet here I am."

She leaned into the glass, her breath making small fog clouds as she breathed onto it. She then glared at Alex. "I'm gonna kill Kara because deep down, even if she won't admit it, Siobhan still dreams of seeing it happen." She then turned to Winn and pointed at Alex. "I'm gonna kill her for the fun of it. And then, I'm going to let Siobhan surface just enough to watch with her own eyes, as I kill you. And once the only person giving her the strength to fight me is gone, she'll be just as dead. And I'll be what I've always wanted to be since this curse started – free, forever."

Winn, and even Alex, felt a frisson of fear travel through them. As much as they wanted to believe that there was a way to bring Siobhan back, to force the Banshee out; it was becoming clear, that might not be possible. And now there only hope against a rampage of murder, was a few inches of reinforced polycompound glass, and the manpower of the prison guards.

"Winn, we need to go," Alex said calmly.

"We can't just leave her like –"

"Winn, now!"

Win followed Alex back toward the door. They tried to remain looking forward, but they could hear the Banshee laughing behind them.

"See you soon, Winnie," the Banshee said just before the door closed and she was alone.

The Banshee was laying on the bunk in her cell. Well, her new cell. They still hadn't transferred her back to Siobhan's original cell since they didn't know how to transfer her safely using the current technology. So, as it stood, she was completely cutoff from the normal cell block. No interaction, not even from the guards. Her meals had been delivered by drone. She was alone since being put in here and since Winn and Alex had left yesterday.

Another inmate in her place would've gone insane. But the Banshee smiled at the treatment. They were afraid and she relished in it.

As she was imagining what she'd do when her opportunity to leave arose, she heard the door leading into this – solitary confinement was the best term she could come up with – leading into this area open and slam shut. Two sets of shoes echoed in her ears, one more pronounced than the other. "You got a visitor, Smythe," she heard a male voice – a guard – say.

She didn't move or even open her eyes.

"Hey, Smythe."

"Siobhan, isn't here."

"That's right," came a female voice that the Banshee didn't recognize from any of Siobhan's memories. "You're the Silver Banshee, correct?"

"Finally, someone with manners. Now who are you?"

"I represent an organization dedicated to protecting this planet from –"

"From people like me?" the Banshee asked, still not finding a need for her to get up.

"From the person who put you here."

"Supergirl? You want to protect the Earth from National City's favorite hero?"

"From an alien threat; even if that threat masquerades behind good intentions and a cape."

"And you think I can do something about that?"

"I was watching the news all those months ago when you and your colleague, Livewire I believe her name is, battled against her. "You had the strength to stand toe to toe with her. Your friend had her down. If those firefighters hadn't intervened, you might not be here today."

"So, you want to what? Arrange another meeting between me and Little Miss Blonde Ambition? Because if you haven't noticed, I'm a little indisposed at the moment."

"I have many friends. Friends with the same belief I do about the growing alien menace on Earth. Like me, they also know it would be best to have people such as yourself, and a few of the other metahuman inmates in here on our side. Agree to help, and we can…arrange to have you released."

The Banshee finally rose from the bed. She walked up to the glass, and looked at the woman who'd been practically teasing her with what she wanted. She was surprised to see that this woman was at least a half-foot taller that Siobhan's five-foot-six. "And just what's in it for you?"

"A protected Earth, and justice for my son, who an alien had imprisoned for merely wanting to do the same thing I'm asking of you now."

This woman is delusional to think I'll just follow orders, the Banshee thought. Then again, she further mused, a way out of here, is a way out of here.

"Deal."
