A/N: Thanks for the comments. To the Guest reviewer, Alex having the Black Mercy will generate some angst for them as will (hopefully) become apparent in this chapter.

"I think this will work, but Max and Alex set it up last time." Winn said. "So there is a chance, like a really big chance, that it could kill both of you."

"Without it Alex is dead anyway." Kara reminded him.

"But you're not." Winn pointed out. When Kara glared at him he added. "Fine it'll be ready in two minutes."

"You sure you want to be the one to go in?" J'onn asked. "I could do it, so could Maggie."

"I'm the most qualified. I mean I have experience with the Black Mercy, neither of you two do." Kara reminded him. "I also know how Alex got me out. I could use the same method."

"It may not be that easy." J'onn warned as Kara hopped onto the bed next to Alex. "Remember you probably won't have powers."

"Maybe. But J'onn I am not leaving without her. Don't pull me out."

Opening her eyes Kara saw herself in a familiar place, Midvale. Looking round she saw the house she had grown up in on Earth and walked towards it. As she neared she heard the familiar voices of Alex, Maggie, Eliza and unsurprisingly Jeremiah.

Entering the garden she was seen by Jeremiah, who was manning the barbecue.

"Can I help you?" He asked causing the others to turn and face Kara.

"Alex, you need to come back." Kara said looking directly at Alex.

"Back where?" Alex asked.

"Home. This isn't real."

"What are you talking about?" Alex asked.

"You've been attacked by a Black Mercy."

"A Black Mercy?" Jeremiah asked confused.

"An alien parasite." Kara said as she kept looking at Alex. "The same thing you saved me from."

"Do you know her?" Maggie asked Alex.

"No." Alex replied.

"Perhaps you should leave." Jeremiah said to Kara as he moved to Alex and placed a protective arm round her.

"None of you know me?" Kara asked feeling winded.

"No. But it is clear you are troubled. So why don't you let me call your doctor or your family." Eliza offered as Maggie took out her phone.

"I don't need help. I need my sister." Kara said.

"You have a sister?" Maggie asked.

"Alex is my sister."

"I'm an only child." Alex said.

"No you're not." Kara said. "Eliza and Jeremiah adopted me after my planet was destroyed."

"Your planet?" Jeremiah asked doubtfully.

"Alex, my cousin is Superman. He was friends with your parents." Kara started to say.

"Super who?" Maggie asked. "Is he a comic book character?"

"You don't have Superman?" Kara asked.

"No." Eliza said.

"Any superheroes?" Kara pressed.

"Like in a cape?" Jeremiah asked. "No."

"What about aliens?" Kara asked.

"Only on TV." Maggie added. "Which I think you have watched too much of."

"No Alex, I know why you want to pretend I don't exist, but I do. And back home Maggie is there too and she is really worried about you."

"I'm right here." Maggie said. "But you are clearly not here mentally. I don't know what happened to you, maybe your sister died in an accident and you are projecting but whatever it is it is not real."

"I am real. So are you Alex. Everyone else are just in your imagination. Please come back Alex. I need you. I need my sister back."

"Okay, I really think you should leave now." Maggie said stepping between Kara and Alex. "I've called some friends at the station and they'll be here soon to take you somewhere safe."

"Not without my sister." Kara said forcing herself past Maggie and up to Alex. "If you don't want to come back for me, come back for Eliza and Maggie." She said as thunder roared. "Come back for J'onn. This isn't real and you know that. What about Jeremiah? He needs you to find him." She said as uniformed police appeared and started to drag her away as the ground started shaking.

"This is what happened in my fantasy." Kara cried at Alex. "It means you are winning. Keep fighting."

"Kara?" Alex asked confused.

"Yes." Kara cried relieved as she struggled to free herself. "Come back. Fight back. This isn't real."

"Alex ignore her." Jeremiah said hugging her. "I am real and I'm right here. I will always be with you."

"No Alex. Fight. It isn't real." Kara cried.

"I know. Damn it Kara, you ruin everything. I just wanted to be happy." Alex said confused and upset.

"I know. But it's not real. Maggie is waiting." Kara cried as the police dragged her off while tasering her. "Fight." She screamed moments before she fell unconscious.

"Easy." J'onn said as Kara bolted upright panting.

"J'onn? Did you pull me out?" Kara asked looking round at Alex who still had the Black Mercy on her.

"No. You came out by yourself." He said.

"Did it work?" Maggie asked.

"I don't know." Kara said looking upset. "I thought I got through to her, but...why isn't she waking up."

"You took awhile to come out of it." J'onn said.

"What if I failed." Kara asked just as the creature slithered off Alex.

"Alex!" Maggie called as she squeezed her hand.

"Maggie?" Alex asked opening her eyes. "You're here?"

"Of course I'm here." Maggie said as Alex sat up and hugged her. "We're all here."

"Not all." Alex said sadly as she clung to her. After a moment she looked round and asked. "Where's Kara?"

"She's right her...she's gone." Winn said realising his friend was no longer there.

"Where are you going?" J'onn asked noticing Alex was trying to stand.

"I have to talk to Kara."

"No, you need to rest." J'onn said. "We don't know what other effects the Black Mercy has on humans. When Hamilton has given you the all clear you can leave, not until then." He then gently reminded her. "Kara just risked her life to bring you back. Don't put your life in danger again."

"Please, I need to talk to her."

"I'll bring her back." J'onn said. "But you stay here."

-00-

"You okay?" J'onn asked as he joined Kara on the balcony.

"J'onn, hey." Kara said turning and forcing a smile.

"You want to talk about whatever it is that upset you?"

"Not really." Kara said returning her gaze to the city.

"Let me guess, Alex's fantasy wasn't what you expected?" J'onn probed.

"More like it was what I feared." Kara explained.

"Want to talk about it?"

"Not really." Kara said.

"Well I'm here if you change your mind. In the mean time I would be grateful if you talked to Alex."

"Why?"

"She is desperate to see you and is threatening to escape. If you handle Alex I will investigate where the Black Mercy came from." J'onn offered.

"I really doubts she wants to see me." Kara said.

"Kara, remember when you were under the control of the Black Mercy, your fantasy world only focused on a small aspect of what you'd want in your perfect world. It is part of the way the Black Mercy keeps control. It keeps it simple." J'onn explained.

"I know. It's just….it doesn't matter. I'll go talk to Alex."

"Kara, where did you run off to?" Maggie asked as Kara reentered Alex's room.

"Just to clear my head. It was kind of disorientating being there then being back." She then turned to Alex and asked. "How are you feeling?"

"I'm fine, thanks to you."

"I didn't really do anything." Kara shrugged.

"Seeing you are stuck here for a bit I'm going to get some food." Maggie said trying to give them some space. She looked at Kara and asked. "You want anything?"

"No thanks." Kara said earning a worried glance from Maggie who silently left.

"You sure you're okay?" Kara asked Alex. "I mean shouldn't you be sleeping or something?"

"I'm fine. Can we talk?"

"About what?"

"You know what." Alex said.

"There's nothing to talk about." Kara said. "You weren't in my fantasy either."

"But-" Alex started only for Kara's phone to interrupt them.

"Sorry, I have to go. Get some rest." She said rushing out of the infirmary.
