Barry was running.

He was usually running, but this time was different.

This time, he was running from a friend.

To an enemy.

...

How did it come to this? How did he end up running from Supergirl to the Dominators?

Oh, yeah. Flashpoint.

How could he forget?

It had been the biggest mistake of his life.

Ironic, huh?

Something he'd wanted his entire life ended up being the dumbest thing he had ever done.

Then he saw it. He had almost missed it, but he hadn't.

It was the Dominator's ship.

He ran on before Kara could stop him.

...

Kara stared in shock as the ship that Barry had ran into disappeared into the sky.

How could he do this to Earth? To his family? To Team Arrow?

To her?

...

Kara didn' know how long she stood there, staring at the spot where Barry had disappeared.

At some point, she felt tears, but she didn't care.

The thing that had mattered most to her was gone.

What did anything matter anymore?

...

When Kara realized that everyone was waiting for her, she turned away from where the ship had been.

How was she going to tell them that Barry had gotten away because she wasn't fast enough?

...

"Kara... where's Barry?"

She shook her head slowly.

"He..."

Iris gasped, a hand covering her mouth.

Felicity just broke into sobs, Oliver hugging her close.

Team Legends stood there, some running to comfort people, others standing strong.

Joe tried to comfort his daughter and keep his tears in check.

Kara just held her head in her hands and sobbed against the wall.

...

They had a funeral.

All of them knew they would never get Barry back.

There was no way.

He was gone, and alien technology would make it stay that way.

Kara would never forget it.

She had never been in love.

Sure, she had some crushes over the years, but that was it.

She had loved Barry.

And now he was gone.
