"Why did you choose the side of evil?"

"You're too consumed by vengeance to see things clearly."

"You're not my friend. Not anymore."

"You're gonna pay for what you did to Iris."

"You're sick."

"You're nothing but a killer."

"You know how much we love each other, and you know how to use that love against us."

The voices in Crystal's head stopped as she opened her eyes and focused on what's real. Standing under a large tree, hiding in its shadow, she watched Barry Allen, his friends, and his family mourn beside the grave of Cisco Ramon. Lisa Snart had showed up as well, as she was devastated by his death. Her brother, Leonard, held her close to comfort her. It touched her how much the two criminal siblings cared about each other. As everyone gave their speeches, Crystal stayed behind the tree, afraid to confront everyone after the revelation of what she has done throughout the course of the month.

The explanation of her return caused some predictable and unpredictable reactions among Team Flash.

Kid Flash says, "You are unbelievable, you know that, right?"

Jesse Quick says, "Just when I thought you couldn't get any lower, Frosty."

Joe says, "Be glad Barry care about you or you'd be biting the bullet literally."

H.R., meanwhile, welcomed Crystal back with open arms, which he used to give Crystal a hug. He said, "It was her, not you, Caity." It surprised everyone how forgiving H.R. was and how much he believed that Caitlin Snow and Killer Frost were "not" the same. Barry empathized with him because he knew how he felt.

Crystal didn't even bother to apologize, since she believed they would never forgive her. All she wanted was to answer every question regarding her ruse and deception. She had only wished that Cisco had lived through the final battle. As comforting as it was to hug him one more time, it hurt her that it was the last time they would ever share a friendly moment. Thanks to Savitar, she will never know how Cisco truly felt about the revelation aside from mixed feelings upon discovery.

"I'm really sorry, Cisco," she said.

Everyone had made their speeches, except for H.R., who wanted to say his last. He takes out a piece of paper and reads it. He then crumples it and tosses it away.

"When I first came to this Earth, I tried to make a connection with the people who put their trust in me. Ramon was complicated, mostly because he's had a connection with other Harrison Wellses. One was an evil mentor. The other was a well-meaning but grumpy older brother. I had big shoes to fill. The fact that I wasn't a genius meant that he and I were doomed to have a rough start. But life has a way of making things work for anyone. Franc... Cisco and I, we formed a bond unlike any I've ever forged. He helped me realize my purpose here on this Earth, and for that, I forever thank him. Rest in peace, my friend."

While the others say some more words for their deceased friend, Leonard decided to give his sister an offer to cheer her up and turn her life around for the better.

"Sis, I know you love the chaos that Frost has brought upon Central City, but I think it's better if you return to the Waverider with me," said Leonard.

"You mean be a hero?" questioned Lisa.

"It's what Ramon would want," said Leonard.

"I guess so," replied Lisa.

"He'll be proud of you if you did," said Barry.

"Trust me, Snart. This is the best way you can honor him," said Gypsy. "If what you felt for him was real, then you can't disappoint him, as I know I can't."

Lisa wasn't so sure about accepting the offer. "But Central City..."

"Needs to be free again," said Barry. "I'm sorry, Lisa, but if you really loved Cisco, then you know what you have to do."

Lisa looks at every single person around her. The looks on their faces all meant the same message. Lisa looks back at her brother, who was holding his hand out, waiting for her answer. In the end, she grabbed his hand, accepting his offer to rejoin the Legends.

After the funeral, Crystal Frost had disappeared, much like Black Siren when she vanished after Savitar's defeat and everyone was occupied by the revelation of Crystal Frost's true identity. The three speedsters had searched for her all throughout Keystone, but she was nowhere to be seen. When Team Flash returned to Mercury Labs, they found a flash drive with a note under it. It had a snowflake sketched on it, telling the team who it came from.

They plug it in to find a video message from Crystal.

At A.R.G.U.S., a package was sent to Director Lyla Michaels. Inside was a drive and a note with a snowflake on it. She decided to play it in private since no one in A.R.G.U.S. besides her knows that the white-haired female who broke into the facility with Barry Allen and Leonard Snart is actually Caitlin Snow.

"Hello. My name is Caitlin Snow, but you already knew that, just as you know my other name. Killer Frost. I bet your were expecting me to be turning myself over to the authorities to serve a life sentence for all the horrific crimes I've committed, but I can't do that. Now, I know that everything I've done is unforgivable. I've killed so many people that I deserve their fate. So many lives were destroyed because of my actions. I've hurt the people I called my friends, my family. I am probably the most despicable person on the planet, and I deserve that title, zero doubt. And I will pay for my crimes, but I can't do that from inside an A.R.G.U.S. cell.

Now, I would like to send a message to each and every one of you. Jesse, Wally, I left a little gift in you two. $500,000 in cash from my operations in Hub City. It's all yours, for your future, and for future baby Flashes. H.R., Tracy, a permit for the rebuilding of S.T.A.R. Labs. As soon as you rid Central City of the Rogues, you can get started. Joe, I've contacted Singh, under an anonymous alias, and recruited for you a police force that can protect Central City once you take it back. Trust me, I know people. I know that these acts of good will are not enough for you to forgive me, but I'm not expecting any. I'm just trying to take the first step towards redemption.

Oh, and Director Michaels, in case you're planning on tracking me down, I'm not gonna stop you. You can hunt me down to the ends of the earth until you fall off the edge. You'll never find me, but should the need arise, I'll find you.

Now, I have one last message, and it's for Barry Allen..."

Barry looks closer at the screen and listens carefully to Crystal's message specifically for him.

"I told you that I didn't need your forgiveness, yet you gave it to me, despite all the pain I've caused you. You truly are the mirror image of Savitar. To think that someone who has lost so much, suffered through so much pain can still remain in the light and see the beauty in everything. Only a true hero can be like that, and that is what you are. Don't ever think otherwise. For so long, I blamed you for what I became. I hated you for turning me into a cold-blooded killer. But now, I realize I only have myself to blame. I made my choice, and I have regretted it every single day.

I wish I can be by your side and kiss you, but, Barry, we just can't be. I know you love me, but I'm not the one. Choosing the person who took away your soulmate, you may be able to live with that, but I can't. I could never. I will always, always love you, Barry Allen, but you have to find someone who not only makes you happy, but makes you complete. Someone who has so much light in her heart that she attracts you the same she does you. Someone who's life is so full of hope, she practically wears that symbol on her chest. I think we both know who that person is."

Barry smiles, knowing exactly who Crystal was talking about.

"Until next time, Flash. Oh, and one other thing, despite everything that happened between us... I forgive you."

The message ends with Crystal blowing a kiss to Barry, which includes a heart shaped snowflake. Barry was smiling even wider as tears of joy started raining down his cheeks. While he was sad that she wouldn't accept his love, he was happy to know that she is out there and safe and finally free.

"She is unbelievable," commented Jesse.

"She's done a lot of things that fit that description," said Barry. "But that doesn't mean it's a bad thing."

At the Rogues' warehouse, the Rogues were counting all of their money or, in Trickster's case, making snow angels using money. Suddenly, a gust of wind was felt as three yellow streaks appeared in the warehouse. Flash, Kid Flash, and Jesse Quick grinned at the criminals with an unconscious Roy Bivolo lying on the floor.

"Hi," greeted Flash.

"Oh, shoot," cursed Top, pouting.

"Oh, shoot, indeed," said Jesse Quick.

"This city ain't yours anymore," said Kid Flash.

After taking the Rogues to Iron Heights, the speedsters work on cleaning up the streets of Central City, with help from Joe West and the police force that Crystal Frost assigned to the CCPD. It took hours, but almost every criminal in Central City was apprehended. All that was left was to rebuild the city, and it just so happens that an unknown person who goes by the name "Crystal Frost" has sent some people who could help with the rebuilding process. Some worked from Keystone City have even offered their assistance.

As the city slowly rebuilds, Team Flash celebrate at a bar, along with Cecile.

"To a bright new future," said Barry.

Everyone clinks their bottles before drinking.

"It certainly feels good to win for once," said Tracy.

"On Team Flash, you'll get that feeling every day," said H.R.

H.R. and Tracy share a quick kiss.

"I must admit, it was nice of Caitlin to help save the city," said Cecile, reluctant to feel proud of her but feels so anyway.

"I think we can all agree that it was Killer Frost who ruined this city, not Caitlin," said Barry.

"Keep telling us that, Barry," said Jesse sarcastically.

"I guess it's time for us to move back in," said Barry. "Joe, we can have the old house rebuilt."

"You really want to do that, Barry?" asked Joe.

"Look, Joe, I know it'll brink back memories of Iris, but that's not what that house should stand for," said Barry. "It should be a reminder that no matter how many bricks are knocked down or how much wood is burned, we always find a way to rebuild. It's what Iris would want."

"She would," agreed Joe.

Suddenly, a quake occurred, followed by thunder rolling and lightning flashing in the sky.

"Oh, what now?" complained Wally.

"Earthquake?" guessed Tracy.

"No, it's something else," said Jay.

Team Flash exit the bar to see an unusual kind of lightning storm descending upon Central City. People were running left and right, trying not to get struck. Cars are flipped. Buildings are damaged. It all felt like the Central City Catastrophe, as the news called it, all over again.

"It's the Speed Force," said Jay, recognizing the energy in the sky.

"I don't get it. I thought Savitar was dead," said Joe.

"Exactly," said Jay. "When you freed me from the Speed Force prison, you emptied it and now it's become unstable. Now, it's energy is being released everywhere at a disastrous manner."

"How do we stop it?" asked Wally.

"By giving it what it wants," said Barry. "I'm gonna run into it."

"What, Barry, no, you can't do that," said Jesse. "There's gotta be another way."

"There is no other way," said Barry. "The Speed Force needs a prisoner and that's what I'm going to give it."

"But Central City needs The Flash, B.A.," said H.R.

"And they do have. Two of them," said Barry, looking at Wally and Jesse. "I know you two can do it. It's time you take off the training wheels."

Barry gives Wally a hug, and then gives one to Jesse.

"Barry, think about your choice," said Jay. "The Speed Force prison is more than just a prison."

"It felt like hell, Barry," said Wally.

Suddenly, a breach to the Speed Force opened. Stepping out of it is a person with a face that is familiar to a certain few of Team Flash."

"Barry, it's your mother," said Joe.

"Barry isn't going to hell," said Nora. "But like all runners, he's reached his finish line."

The lightning strikes continue as the people panicked and ran for cover. The energy from the Speed Force is becoming even more unstable every second. Barry knows he has to go now, but not without saying his goodbyes.

He approaches H.R. and Tracy and says, "Good luck. Both of you. You two need each other."

Barry hugs H.R., who wipes his tears with his drumstick. He then gives Tracy a hug.

There was only one last person to say goodbye to. Joe. The man Barry had called his father and was proud to do so. Joe was clearly saddened by the thought of losing Barry when he had already lost Iris.

"We spent so much time trying to save Caitlin, you didn't mention that we were supposed to save you too," said Joe sadly.

"You did save me, Joe," said Barry, smiling. "You took in an 11-year-old boy with a broken heart, gave him a home, and so much love. No son ever felt more love from a father."

"And no father ever felt more love from a son," said Joe, on the verge of crying.

Barry and Joe hug one last time. It hurt them both that this could be the last time they'll see each other.

"My beautiful boy," called Nora. "It's time to rest."

Barry walks towards his "mother" and holds her hand as she walks him into the breach. Barry took one last minute to look back at his family. He smiles at them, trying to reflect some more hope into them. In his last few seconds with them, he wanted to make sure that they won't let this event bring them back into the darkness. Like Crystal told him, a true hero would always see the light in the darkness and that's what he's trying to teach his friends, all with a simple smile.

Barry and Nora enter the Speed Force as the breach closes. The lightning storm ceased. All Team Flash can do now is process how they're feeling right now.

Deep within the shadows, a white-haired figure watched the whole thing happen. She, too, was stricken with sorrow to see Barry Allen enter the Speed Force, but she chose to walk away and hide rather than approach Team Flash.

Eight months later...

At a hospital in Gotham, a woman was giving birth to a child. Doctors were present in the hospital room housing a young brunette named Crystal Frost. She was in so much pain right now because the baby is coming. The doctors and nurses present in the room put on their masks as Crystal did what she was supposed to do. In the end, the baby has arrived.

"It's a boy," said the midwife, holding the baby in her arms.

"Give him to me," asked Crystal, eager to hold her child.

The midwife gives the baby to Crystal. She smiles as she looks at her beautiful baby son. He was so cute, she had to poke his nose.

"Do you have a name for him?" asked a doctor.

"Bartholomew," said Crystal. "Bartholomew Henry Frost."

THE END

Caitlin has a son! Yay! Do you have an idea who he is? He's not an OC. He's based on a character from the comics. I'll give you a hint: Read the first four letters of the baby's name.

And so, that concludes "Unbelievable". I'm sure you're expecting the sequel involving our heroes fighting Darkseid to come next. Well, I may have to postpone that. I'm planning a Killer Frost spin-off. If you want a hint, it's a Suicide Squad-style story that will feature Killer Frost with her own team to fight some villains. Trust me, it's more complex than that.
