In an unknown space-region

"Kara Zor-El". A familiar voice calls to Kara. "Awaken".

"Who's there?", Kara questioned. She motionless lids in tears.

"The answer to that is obvious". His body materialises in front of Kara. Supergirl just lost her grasp in reality, left in tents of ponders.

"It can't be", Kara cries, identifying the character to be someone she knew before, but was learnt of his apparent death. "Dad!". Tears burst in watery-flames. "You were-".

"I am not your dad. Just a holographic interface, created to follow your every command", AI version of Kara's father spoke. "As far as you need to know, you're far from reaching the true potential of Timan-El".

"Timan-El?", Kara followed.

"A device operated to edit the timeline itself", the AI explained. "It was built as back-up, should Krypton ever come to the point in destruction".

"Why was the Timan-El within Earth's land?", Kara questioned.

"Your father sent Timan-El to Earth, to authenticate that it will be used to restore Krypton, if it was ever to explode. Which it did"

"Well he's done a pretty good job putting it quite a risk. There would've been a chance that Non or Astra could've accessed the Timan-El for themselves"

"Not quite, Kara Zor-El", the holographic man disagreed. "Your father habituated its use under your DNA".

"My DNA?!", Kara exclaimed.

"Now that you have been lecture enough about Timan-El's description, it's time to assemble back the pieces you lost"

"Pieces?", Kara followed. Pints of flashes awaken in her mind. Flashes of all the people she failed to save. Her father. Her Aunt Astra. Earth-friends she befriended from her early youth to an adult. Her reared family. And her boyfriend. "I remember". Kara reconciles with her true meaning to glorify her new path; to build a new timeline. A timeline where everyone will immediately get to be brought back to life.

The device wise instructs Kara on how to use Timan-El. Kara pursues every line the tech instructs her to sequence. Kara taps on the top cube. Cube's lid opens, opening a wide beacon of flashlight. Taking Kara inside, into a spiral blue-black physical stenches.

Kara eyes on every side she can glimpse in. Images of a variety of moments, times, and ships. Wasn't just shown display of her world. There're billions of worlds, realities and their possible futures. Kal-El bowing down to one of Supergirl's cousin's greatest adversary. Gotham surfaced as 'No Man's World'. An Emerald Knight against a yellow variation of itself. An Amazonian reined in conflict with her arch-nemesis. Joker War. Eobard possessing the Barry Allen's body. A brutal aged Batman thrusting his sword in Reverse Flash, killing him. Aquaman and Wonder Woman despise each other, transforming their peace treaty into an aggregated war. Too many realities, and worlds Kara failed to resist looking away.

Ignoring all the images rolling over her, Kara directs her eyes inside her head, focusing on something that needs to change. She had two options. To resurrect Krypton by changing the notions they were fated to blow in, or focus her gazes on Earth. If she resurfaced Krypton, her father will life in flesh. As all Kryptonians would still be shaped in same state, just like in Argo City. It wouldn't make much of a difference. But Kara loved his father, she was tempted in bringing her father back to life, but that was close her connections to her adopted family and friends. Kal-El would never be gifted as Superman, on Earth. Kara and Kal could live peacefully on Krypton. But it'd signify erasures to all affiliations her cousin tied into. His Earth-name, his adopted loving family, his friends, even his own wife and birth-baby. At least everyone will come back. No one will invade the Earth. No alien, terrestrial will invade Earth. If Kara reforms her relations to everyone on Earth, she can change the situations every died in, and assure that they will carry on. These her two options.

Kara quickly glances over to Oliver's corpse. Completely stationary.

"I never wanted this darkness and tragedy to blend in your life, I wished I could be a better girlfriend, and maybe a mold spouse of yours", Kara expressed. "I'm sorry Oliver. I'm going to have you erase our bond for each other. You can finally be safe and-". She failed to utter, an indulgence of heist decks on Kara's wrist.

"Don't do what you think you are going to regret", a familiar voice dwells inside Kara. "Mistakes will break you. Like it did to me".

"Oliver?!", Kara exclaimed.

"Don't sell your life away. Your life is previous to yourself"

Kara eyes down on Timan-El. "Is this projecting Oliver's soul?".

"Must be hard to contain your feelings inside". A familiar voice dazes over Kara's ears.

"I know that voice", Kara declares, rotating to see a man in a black trench coat. "Bruce?". She clearly coudn't see his face, his face overshadows in darkness, right about his forehead.

"Remember the time when I trained you, one of the fundamental truths I gave you was to never corrupt yourself, to never destroy whatever's inside you", Bruce lined. "You did fracture it, though under inconsiderate circumstances, which I helped cure you off when you were dosed of red kryptonite".

Kara remembered someone plunging a needle on her arm, when she annihilated many cities last year. It was Bruce Wayne.

"Why are you telling me all this?", Kara demanded. "And how did you come here?".

"That information will not be answered to you", Bruce stricted. "I want you to remember the lady you are supposed to be. What your cousin Kal-El wanted you to be".

"How can I be better person when all I'm doing is flourishing bodies that send their souls to some other world?!"

"You will figure it out", Bruce believed. Latter gestures his head to motion Kara to continue. "Go on, forge your path".

Kara momentarily glances to Bruce, before gazing back down to the Timan-El. Kara shuts her eyes, focusing everything on what she desires. A recreated timeline. A new adventure. Supergirl will either die a hero, or live long enough to see herself the villain or a normal inhabitant. Those are signed in Kara's list of choices.

Bruce Wayne impartial his eyes on the yield Kryptonian.

The same light outbursts over Kara. A smooth volcanic eruption. Addressing Kara to a new direction. To her mindful reality. A reality wised in her favour. She hardly spared a time to save her loved ones in one timeline, she can erase it, and start a new one.

A/N: This marks the end for this story. Sorry that the story had to be quite short. Wasn't too keen in carrying with Non's Invasion for long. You might think that it has no significance, but it does have some aspects that bridged Kara to using the only thing that can save herself from the darkness.

I'm aware in DC Comics, Supergirl doesn't have much relation to Batman, although once lining him as a pain in the ass. Felt like it'd be nice to display their relations as mentor-to-student figure.

In Injustice 2 game, Batman was meant to be more considered of a mentor to Supergirl. Loved their relation. It was awesome seeing them together. Not as lovers. But as allies, and for Batman to be a teacher. I didn't see how their relations are displayed in DC Comics, I only briefed on a few chapters, including the Injustice Year One to Five. And to say this: it was a heavy conflict. Especially the war between Superman and Batman. World's Finest shattered. A concept of that will appear in future stories, inspired from someone else's story, whom hadn't completed his.

A sequel will appear soon. So again: stay tune for the next story. Might be halt a delay since I do want to continue with all the other chapters I left behind without editing, a week ago. I did one edit on one, but needs to me consistent. I'll make sure it happens.

Thanks for reading (:
