My goal here is to explore Kara's journey and not technological development.

Bia Zor-El, I would never thank you enough for your help in every step of the writing process. You are my Master Yoda. The title was also Bia's idea.

I hope you like to read it as much as I liked to write.

Warning: The mistakes are all mine.

Disclaimer: Supergirl's characters belong to DC, CW and WB. (Did I forget something or somebody?). The new ones here are mine.

Kara always had to deal with something no human, in any circumstance, had to: her longevity.

She would always be the girl who lost everything.

New Beginnings

Chapter 1: "If I could make days last forever"

"If I could save time in a bottle (*)

The first thing that I'd like to do

Is to save every day

'Til eternity passes away

Just to spend them with you"

Kara Zor-El knew the exact moment Kara Danvers died. She knew when and where. She didn't even need to close her eyes to remember that early morning at the beach like a movie.

Through all her life she lost a lot. On Krypton: Parents, friends, culture, planet. On Earth: Mon-El's departure, then one by one – Astra, Jeremiah, Eliza, Cat, Winn, James, Lucy, Lena - people around her died except J'onn who returned to Mars with M'gann and, dealing with his own ghosts, Kal, who still lived in Metropolis. Each loss made her more conscious of her longevity and solitude.

The DEO still existed and Supergirl still worked for them, but most of the time they could deal with the aggressive aliens. She also patrolled the city and the world helping in whatever she could. As years went by, even with the DEO constantly updating her documents, her evident slow aging process made being Kara in the same public place impossible, so she left CatCo and moved to a small and cozy shack in the mountains where she could enjoy peace. After all, transportation wasn't a problem for her.

Married, Maggie and Alex adopted two kids. Later they had grandchildren and, after that, great-grandchildren. They were all very close. After retirement, the couple moved to a beach house in Midvale. Bringing food and flowers, Kara usually joined them. Although they had some disagreements, – and they laughed remembering those days - the younger Danvers and the detective started considering each other sisters a long time ago.

Kara had always been 'Sunny Danvers', and that didn't change. She was kind, caring, and helping people was what she would always love to do. The Kryptonian loved all her Earthly family, her nephews, and nieces, and no matter what they needed she was there for them. She had lovers, relationships and friends, people were around all the time, but inside, Kara gave up letting anyone be completely part of her life. It was too painful. Alex and Maggie or, as she called them, her 'old girls' were, in fact, the last real bond Kara allowed herself to have.

Although teasing Maggie about her healthy eating habits, Alex was worried because her wife was weirdly tired. When the symptoms worsened, the agent gave her an ultimatum.

"I'm an old woman, Danvers. It happens." Maggie replied.

"74 is not old. For me, you're still hot like hell, Maggie Sawyer, but I'm going to book a medical appointment just in case."

"You can't force me to go."

"Did you forget that I have an alien and I'm not afraid to use her against you?"

Maggie complained and resisted, but, finally, agreed. Dozens of medical exams later, the diagnosis was even worse than anybody could expect. A very aggressive type of leukemia.

Although Maggie tried to keep things as normal as possible, the disease weakened her fast and Kara moved to one of the three bedrooms of the beach house to help in everything they needed, trying to give Alex and Maggie as much time together and space as possible. Their family was always there for them, and even asked the couple to move back to National City and try some alternative treatments, but they knew that nobody could do anything and refused the offer. Less than five months later, surrounded by her loved ones and with her soul mate by her side, Maggie peacefully passed away. Although Alex was devastated, she was also grateful for the real, full and happy life they had had together.

"Here we are. Like the old times." Alex said a few days later seating at the beach house balcony. Kara touched her hand.

"Like the old times."

"Are you going to stay with me?" the older Danvers asked.

"If you want, I would love to."

Aging was very different for each of them. Twelve years after Maggie died, Kara, at the age of 83 looked like no more than forty-six or forty-eight years old and was at full strength. It was astonishing that Alex lived so much (actually, also Maggie) considering her life as a DEO agent replete of wounds, scars, broken bones, night shifts, and bad eating habits. However, at the age of 85, high blood pressure, dyspnea, osteoporosis, muscle weakness and arthritis she became increasingly slow and after some time even walking got impossible. The simple flu could quickly turn into pneumonia. However, some things the advanced age never took from the older Danvers. Her memory, her brilliant mind, her spirit. The sisters knew that Alex was fading, and they decided to enjoy each second they had left. Since then, every night was sister's night, every day they shared special moments, cuddles, laughs and memories. Kara usually took her flying smoothly at low altitudes. She also brought the agent's favorite meal from the food truck in Chicago. Alex's children, grandchildren, and great-grandchildren regularly went to the beach house especially on weekends, and it was a joy.

Now, at the age of 90, and being taken care of by her sister full-time, Alex was ready for the next step.

It was still dark. Kara woke up from her always light and watchful sleep, checked her sister and after a quick shower went to the kitchen. Looking the beautiful sunrise, she had breakfast and organized some things. After that, wearing flannel pants and t-shirt, she went to Alex's bed kissing her face.

"Good morning, sis. Did you sleep well?" The older Danvers answered with a smile.

"Ok. Just wait a second, and I'm going to get your breakfast." Before the Kryptonian could rise, she felt a hand holding her arm.

"Kara, take me to the beach."

Felling her heart aching and knowing what her sister was asking, Kara waited for a while looking deep into Alex's eyes before answering.

"No."

"It's time."

"I don't want to." The woman's blue eyes brimmed with tears

"Please, Kara. Let's do it together.

The younger Danvers finally nodded. Slowly, carefully and smoothly she picked her sister up in her arms keeping Alex as close as possible to her chest. It always calmed Kara down. Barefoot she took the older Danvers to the beach and strolled making sure that her beloved sister could feel the breeze and the splash of the water.

"Aren't you cold?"

"I'm alright." Alex answered feeling cozy and safe.

"Are you sure?"

"Don't you get it, Kara? With you, I'm always fine."

The Kryptonian didn't want to talk anymore. She just wanted to hug the most important person in her life. Ever.

"It was quite a journey, wasn't it?" Alex smiled tenderly, drying the alien's tears.

"Yes, it was."

"Remember, Kara. Just because I'm not here, it doesn't mean I'm not with you."

"I know."

Minutes later, feeling her sister loose her embrace, Kara broke down crying. She kneeled in the wet sand, washed and caressed Alex's face with the salt sea water and, after that, flew as high as possible. Then she stopped, floating with the older Danvers in her arms.

"'You have been the sun of my life.

My prayers will be the sun that lights your way on the journey home. I will remember you in every dawn.

And await the night I join you in the sky.

Rao's will be done.'"

As usual, I love references, so here they are:
