Disclaimer: I don't own Supergirl or the characters. This is written purely for fun.

A/N: This is set after the end of the last season. To be honest there was little about the Season 5 I could really get into, so the first couple of chapters kind of wrap the season up so that I can get to the main part of the story, which will be focused on the sisters. One thing to note is this is set in winter.

"How is he?" Kara asked when she entered Lena's lab where Brainy was lying on a bed unmoving.

"Alive." Lena said. "But I don't know what is normal for him so I don't know if he is getting better or worse."

"This is my fault." Nia said.

"What do you mean?" Kara asked.

"I was so angry with Brainy I turned my back on him. If I hadn't then I could have had his back and he wouldn't be on death's door."

"Brainy will be okay and you gave him every chance." Kara said, despite feeling the same as Nia. "I know it is hard, but right now we need to figure out where Lex is and what he is up to."

"He partnered with Leviathan for a reason." Lena said. "If he is missing, chances are he got what he wanted and he is going to do something bad."

"Power." Brainy murmured.

"Brainy?" Nia asked hurrying to his side and grabbing his hand.

"After power. Took the bottled gods. Wants to use it. Will kill you all." Brainy said before passing out again.

"Did he say bottled gods?" Nia asked confused.

"Sounded like it." Kara agreed.

"Do you think he's been permanently damaged?" Nia asked.

"Maybe not. Maybe it really meant it." Lena asked. "What if the power of Rama Kahn was bottled?"

"Like a battery?" Alex asked.

"Precisely." Lena said.

"Ignoring the fact that that sounds insane, what would he do with a really powerful battery?" Nia asked.

"Nothing good." Alex said.

"The options are endless, but it is probably safe to assume that he wants to use it to portray himself as god." Lena said.

"You are thinking about the Lexosuit?" Kara asked looking doubtful. "You really think he'd waste it on that?"

"Never underestimate his ego." Lena said. "And then there is the fact that my mother is missing and she played a big part in the suit design."

"But is that even possible?" Alex said. "I mean that much power used for something so trivial could result in it blowing up, the suit that is. Even if he was able to just harness a small fraction of the energy the power would be immense."

"Except Lex would have thought about that and built in failsafes. Only those failsafes will be designed to protect him not everyone else. And if they do get it working not even Kara would have a hope against it. He would be invincible." Lena said.

"So we have to find him before that." Kara said.

"It's not like we haven't been looking." Alex pointed out.

"But now we know what to look for." Lena said. "If they are using it as a power source it will give off e.m. radiation. We may be able to detect it." She then looked at Alex and said. "I could use your help."

"Of course." Alex said following Lena out of the room as Nia's attention returned to Brainy who looked like he was in a nightmare.

"Can you help him?" Nia asked J'onn. "I mean telepathically."

"Like Kara he seems immune to my powers." J'onn said. "But he is strong."

"He'll be okay." Kara said trying to reassure her friend as Brainy's eyes opened once again.

"Brainy?" Nia asked grabbing his hand again wondering why he wasn't moving.

"Too much power. Can't be contained." He said. "Must be dissipated. No where on this planet safe." With that he passed out again.

"Just in case his warnings are because ... "

"His brain is fried?" Nia suggested.

"I was going to say because he is delirious." J'onn lied. "Either way, just in case we are following the wrong lead I am going to go talk to my contacts and see if they have found anything yet."

"Call if you need anything." Kara said.

"Of course." J'onn said leaving.

"Hang in there." Kara said to Nia.

"I just feel so guilty." Nia confessed.

"Brainy chose his own path." Kara reminded her as Brainy started mumbling.

"Is that even English?" Nia asked not recognising the words.

"I don't think so. And I don't recognise it." Kara said as Alex came back into the room.

"Did you find something?" Kara asked.

"No. We set up a scan, but it could take awhile. What's he saying?" Alex asked walking over to Brainy and looking at the machines he was hooked up to.

"I don't know." Kara said. "He's no longer talking in English."

"His brain activity is through the roof." Alex said looking at the scan.

"Is that a good thing?" Nia asked.

"I don't know. Brainy always kept details of his physiology secret. He didn't want to damage the timeline." Alex explained. "The good news is his last blood work showed improvement." She then looked at Nia and said. "But there is a chance that if he does wake up he won't be the same."

"Or he might be the same." Kara said optimistically as Lena came in holding a tablet.

"I think I may have something." She said.

"Already?" Alex asked surprised.

"There is a large noise source and the power it is emitting is increasing. It's not like anything I have seen before." She said showing Alex the tablet.

"Me neither." Alex agreed. "And if the emissions keep growing we are going to have a major problem on our hands."

"Technically it's not your problem." Lena said. "I mean you aren't government anymore. Should we call some one who can legally act?"

Before Alex could respond Nia called to them. "Guys!"

"What?" Alex asked turning.

"Kara looked at those coordinates and left."

"Damn it Kara." Alex said reaching for her phone. As soon as Kara answered Alex asked. "What are you doing?"

"If it is Lex we need to stop him before he does something that can't be stopped." Kara said.

"If it is Lex you need back up." Alex warned.

"There's no time." Kara argued. "If something has gone wrong I need you to come up with a way to fix it." She added. "I've arrived."

"Please be careful." Alex pleaded.

"Always." Kara said before using her x-ray vision on the building.

"This would be a very good time to turn it off." Lex said as the power source glowed from where it sat in the Lexosuit on the bench in the lab.

"It is not that easy. It seems to have started a chain reaction. Everything I have tried, it has adapted to. It is like it may be sentient." Lillian said.

"It may be. And if it is, that is one intelligence that will want to destroy the planet." Lex said.

"We could programme the Lexosuit and fly it into space." Lillian said. "Except if is sentient it may be able to take control of the Lexosuit."

"Has your attempt to play god backfired?" Supergirl asked walking into the lab.

"No one likes it when you are preachy." Lex said as he furiously typed at a console.

"It looks like we find ourselves on the same side again. Let's hope you will be more useful than Jeremiah." Lillian said to Supergirl.

"Shut it down." Supergirl said while glaring at Lillian.

"If we could, don't you think we would have done that already?" Lex asked.

"You are really telling me you have no way to stop that exploding and destroying the Earth?" J'onn asked as he entered the lab.

"That is technically correct." Lex conceded.

"Deal with them. I'll fly it into space." Kara said ripping the container out of the Lexosuit and flying through the ceiling.

As she flew upwards she heard Alex pleading with her to throw it and get to safety, but she knew she couldn't. She needed to get it to a higher altitude. As she flew higher and the oxygen got less and less she was aware of Lena and Alex shouting at her, but she struggled to hear them over the wind.

"What?" She asked.

"Crack the container." Alex called. "Let some of it out."

"Won't that be bad?" Kara asked.

"Better than an explosion that will destroy the planet." Alex countered.

As she flew Kara tried to break into the canister only to find she couldn't get in. What the canister did do though was burn through the skin on her hands.

"I can't do it. Whatever it is made of is too strong." She said as she flew higher.

"Don't go higher." Lena suddenly shouted in her ear. "If it blows, an altitude of 178 miles is preferable. Stay there and try to open the canister."

Doing as she was told Kara stopped flying and focused her efforts on opening the canister which was starting to get very hot and burn brightly. Giving it her all she finally heard a crack. Looking down she saw the canister, held in her burnt and blistered hands, had started to develop small fractures.

"I've done it." She said.

"Good. Throw it and get out of there." Alex practically screamed.

Nodding Supergirl threw the canister and started to fly away moments before there was a huge explosion and her world went black.
