Now the whole group and Mr. Snart were going to surprise the speedster. When Barry was going to stop a meta human Cold shot him from the back freezing him enough so he wouldn't be able to move. Raven, had other plans in mind. He placed both of his hands on the speedster's head making eye contact. Slowly Barry's eyes turned completely black and so did his scarlet suit with purple lines. Now his lighting was purple as well. The demonic speed creature freed himself from the ice that was keeping him still. Raven got infront of Barry as he said
- Now, be a good boy and show us where your meta friend is. We are going to pay off a little visit.
Snart dropped his cold gun in shock knowing that he helped cause that to Barry. He never wanted to admit it or show it but his appreciation for Barry had been growing since he saved Lisa.
- Barry!
The evil speedster brought Vibe since that's what Raven has been looking for. Cisco was very confused and instantly got spooked when he saw Barry.
- Uh... Barry, what's going on?
The speedster did not say a word. Then he turned around to see the demon with the bright purple eyes. Cold wanted to stop him but Raven back handed him to the other wall near them. John and the others didn't agree to Raven's methods but it was too late to back away from that. Besides they were already the bad guys in Cisco's and Cold's eyes. Cisco was going to oppose to that but Raven interrupted him by saying.
- Try something Vibe, and your speedster friend will suffer the consequences... all thanks to his thief friend. Thanks Leonard, for betraying the person who saved your sister. You really got a cold heart.

Leonard's POV
The fear thoughts looped around in my mind until there was no room for anything else. I didn't mean for this to happen. I only wanted to do what I promised Sara, I would help. They seem to need to get home. If I knew this would happen I would have never agree to this... Sorry, Barry
End of Cold's POV

Omega glanced at the man with the cold gun. He was hurt but that was the least of Leonard's worries. The alien looked at Carbide with concern they both nodded and went towards Raven.
- Raven! Stop this madness right now! We don't have to hurt them. Vibe already agreed on helping.
- Omega... you are trying to side with the good guys. Besides if I free the speedster. Cold would come after us.
- Free him right now!
Raven hesitated. He didn't like to be told what to do. But in Fortnite Omega has the power because the creatures follow him. He free the speedster from his demonic powers. Barry has his eyes wide opened and then fell to the ground unconscious. Cisco stood there in shock as for Cold he dragged himself towards Barry. Cold took of his blue coat to put it on Barry. He pulled the speedster towards him. Gently placing the speedster's head on his lap. Omega got close to them slowly. Leonard pointed at omega with the cold gun.
- It's okay, it's okay I just want to help.
- I trusted your friend once. I'm not planning to make the same mistake.
- Look, this... liquid in here. It helps. It will heal him.
- How can I know you are not going to hurt him?
- Because, I'm willing to be my life on it. You can shoot me and all of us if I'm lying.
Cold was doubting at first. He was worried about Barry and there was no much he could do.
- Fine.
He made Barry take it. Cold was afraid. He was holding the speedster tightly as if he could keep him forever. Len was so busy worrying that he didn't notice when Barry was waking up.
- S-Snart?
- Barry...
Omega placed hand on Snart's shoulder nodding that he'll be okay. Barry didn't even ask for an explanation he knew Leonard only tried to help. Carbide leaned over to Leonard whispering.
- Don't let your past define you. Don't hold back your feelings.
John turned around to look at Cisco.
- I know we are asking a lot specially since we hurt your friend. But we need to get-
- No, don't explain. Just get out of here.

Cisco opened a breach. Cold turned around to look at Omega. His eyes were still a bit watery and softly saying
- Thank you...
One by one got into the breach to go back home. John looked at Drift. He was with a girl and a banana.
- Uh who's that?
- This is Vanessa, my girlfriend. We have lots of years to catch up on. She's such a calamity for the most part.
- So... you are bringing her to Fortnite?
- Yep. So Van, you are going to have to choose a nickname
- Why?
- Because... that's what people from earth do when they get to Fortnite. It would just be plain boring to keep the same name that you have on earth...
then he turned around to see John with a serious face and his arms crossed. Drift looked nervous as he said
- But, in you sounds good, sir.
- Just get in the breach.
Soon they were all finally back home.
