The Fire & Ice [Caitlin Snow/Killer Frost/Snowbarry]

The Beginning of the Prophecy

"Check the Time Vault again, Barry"
Harry suggested

"Yeah, come with me"
Barry said

They went to the time vault after Savitar's departure to check if there's any changes in the future

"There's another information we've gathered"
Harry said

"What is it?"
He asked

"I guess you should look at it yourself"

He saw a footage of Savitar slowly stabbing her, killing her while Flash tried to stop him but he was not fast enough

"I-I can't..."
"NO"
"She can't die"
"Harry help me please"
He begged him

"I'm sorry, I can't for now"
"I-I have to leave as well"

"What?"
"Why?"

"There's a problem with Jesse again and I have to go back to my Earth to fix it"
"I will leave as soon as they know already"

"Can't you stay just after you train me?"

"You can do it, Flash"
"You're the fastest man alive"
"You said it yourself"

"I just can't..."
"Can't let her die"

"Tell them now, they'll help you"

They went to the cortex to talk to the team

"We found footage from the future"
Barry said

"What footage?"
Iris asked

Barry couldn't blurt out the news

"I-It's Savitar"
"He killed..."

"Killed who?"
Cisco asked

"He killed Iris"
A tear dropped on his face

"And I wasn't fast enough to save her"
He added

Everybody was shock

"So are you saying"
"Iris will die?"
Joe asked

"What date is it?"
"The video?"
Iris asked

"Next month..."

"I-I have a month left to live...?"
Iris said

"We won't let it happen"
"I will be fast enough"
"Cisco, Caitlin, Catherine, Wally, Joe and you can help me"
Barry said

"Harry can.."
Cisco whispered

"I can't"
"I mean I can"
"I just can't help for now"

"Why?"
Caitlin asked

"I'm leaving, I have to go back to my Earth"
He said

"Now?"
She asked

"Yes"
"I'm sorry"

"No, I understand, Harry"
"Go back to Jesse, he needs her father there"
Barry smiled at him

Harry left the cortex after saying goodbye

An hour later, Caitlin decided to go home already when she arrived home a letter from Catherine was left at the table for her

"Caitlin,

Yep, I'm still out. I know you'll be home early. or not? I don't know what may happen. I may be still out late so don't wait for me. Call me when you need me, Cait. He's still so handsome even after years of not staring at him. Oops, I mean after years that I haven't seen him. See you later ;)

Catherine"

"Oh Cathy"

*knock knock*

She opened the door and it was Catherine

"I thought you'll be home late?"

"I know how to get rid of your powers!"

"What?"

"You said before that you don't like it right?"
"To be evil like Killer Frost"

"That was before"

"You just have to take and open the Philosopher's stone"

"What?"
"You know I can't do that"
"Plus, it's in S.T.A.R. labs"

"Who said it was still there?"

Catherine brought out a box

"CATHERINE!"
"ARE YOU OUT OF YOUR FREAKING MIND?!"
"You know none of us weren't supposed to touch that"

"YOU WANT A CURE THEN OPEN IT"
"IT'S YOUR CHANCE, CAITLIN"

Caitlin was forced to get it from her. The moment she got the box, Catherine vanished without her noticing. When Caitlin decided to open it, she called her sister.

"Catherine"

But no one answered

"Catherine?"
"Where'd she go?"

Nevertheless, she opened the box forgetting that she wasn't supposed to open it then after that, she collapsed and fell onto the floor.

"Caitlin!"
"Why are you sleeping on the floor?"
Catherine laughed

"What?"
"I-I fell after I opened the box"

"What box?"

"Tha-"
She pointed but realized that it's gone

"What? There's no box there Caitlin"
"Are you drunk?"

"I-I guess?"
She lied

*knock knock*

"Ronnie's here!"
Catherine opened the door

"Hey, babe!"
He ran to Caitlin with a boy

"Ronnie?"

"Yeah...?"
She touched his face to see if it was all real 

"Who's he?"
She asked

"He's your son, Caitlin"
"Are you silly?"
Catherine laughed

"What's wrong with you?"
"Wait..."
"Is she...?"
Ronnie asked

"Drunk?"
"Yes, very much"
They laughed at Caitlin

"What are you guys laughing at?"
Caitlin asked

"Nothing, honey"
"Charles, go to your room"
"I'll talk to your mom"
Ronnie told the little boy

"Charles?"

"Yes, Caitlin"
"Charles Nathaniel Snow Raymond"
"He's our son"

"No, I'm dreaming"
"What's happening?!"
Caitlin panicked

"Caitlin, you're drunk"
"Go get some sleep"
Ronnie said

"I'll make coffee for her"
Catherine said

"What?"

She suddenly collapsed and passed out again
