A Son of Lightning and Ice

Chapter 2

Death of a Universe and Passing down Powers

The sound of Caitlin's heels hitting the floor were what was heard as she reentered the Cortex.

"I ran his blood and it's true he is our son, Barry." She said

Off to the side Iris bristled and threw an angry glare at the piece of paper.

"Why where you sent here?" Barry asked

The future young man sighed, "When I was ten years old the sky turned a dark red and the earth began to shake, and a portal appeared in our home. The last time I saw both of you is when you two entered it. A few minutes later the shaking stopped, and everyone thought that the danger was averted. We were wrong. A few years later I came into my powers and went to train with Oliver Queen, and when he deemed me ready I returned to Central City, and along with Vibe, and Kid Flash or Mach Two as he was called in the future protected the city.

But about six months ago the shaking started again, they were worldwide earthquakes. I don't really understand the science, but basically when my earth's particle accelerator exploded dark matter creeped into the core of the earth, and when meta's used their powers the earth absorbed a portion of the dark matter. Eventually it absorbed too much and was ready to explode. Not only would this destroy the earth but the dark matter would leak throughout the entire universe."

"There was no way to reverse it?" Cisco asked

The young man shook his head, "We tried everything, even time travel. But it seems that it was a fixed event."

"But how did you get here?" Barry asked

"It was my worlds Vibe. Right before the last quake he opened up a breach and sent me through it. I don't know why, I was willing to die with the rest of the universe." The young hero bowed his head.

Caitlin had to resist the urge that welled inside her to hug the man, and out of the corner of her she saw that Barry too had stop himself from stepping forward. The two were brought out of their thoughts as an angry Iris stormed out and Barry started to jog after her, before Joe put his hands up,

"I'll talk to her; you guys do what you do." The officer said as he went after his daughter.

"What exactly are your powers?" Cisco asked

"I thought you'd never ask" The man smirked

In the training room Joel stood in front of Barry.

"Try to hit me using your speed." He ordered

The Flash shrugged and yellow lightning appeared around his fist. As the fist came closer blue lighting entered the time traveler's eyes, but this lightning was a clear light blue, not the dark blue that was caused by the velocity drug. Joel sidestepped the Flash's punch and flipped the man over his shoulder and on to the ground.

With a groan Barry got up.

"I did not inherit your speed, but I inherited your speed instincts. Does that make sense?" he asked. Barry again just shrugged. "I also have the ice powers of Killer Frost."

"I became Killer Frost on your earth?" Caitlin asked

"You did not become her as much as you allowed her out. You and Killer Frost were separate beings in the same body, and you could commutate telepathically as well. I called her Auntie Frost, because she was my fun aunt who let me watch R-rated movies, and have snacks after bed time." The man said with a genuine smile on his face.

That caused Caitlin to grow silent.

"Well you must have awesome stories about Uncle Vibe right?" Cisco asked

The man chuckled. "Quite a few but they mostly involve alcohol and quite a few things I don't feel comfortable talking about with my parents in the room."

Cisco laughed, "Yeah well I'm heading home, oh yeah what do we call you?"

"Joel"

"That's good to know, but I meant what was your superhero name?"

"You never gave me one."

"Well I'll have to get on that." Cisco said leaving

"Joel, you understand that this is quite a shock. Plus it's been a long day, how about you stay here for the night and in the morning we get to know to each other a little better?" Barry asked

"That sounds like a good idea Flash." Joel

Barry nodded and gently shook Caitlin out her thoughts.

"Oh, yeah have a good night." She said as Barry led her out of the room.

A few minutes later Barry had flashed Caitlin to her apartment door.

"Crazy day huh Cait?" Barry asked

"Yeah pretty crazy." She said with a small laugh.

The awkwardness between the two grew until Barry simply said good night. Caitlin parroted the phrase before entering her apartment. As she flopped down on her bed a voice that's wasn't her own spoke in her head.

Hey Caiti it's time we have a talk.
