/ Author's Note: Earth 2 Laurel Lance has a different backstory

Zoom had just unleashed some more Meta humans on Central City. Once such meta-human was attacking Mercury Labs when the Flash raced to stop them. Barry had just arrived on the scene to see Laurel Lance attacking the building with her sonic attack.

"Laurel?" asked Barry.

"Hello, Flash. So, you know my doppelganger? By the way, I go by Siren." asked Siren.

"Guys, the meta human is Laurel's doppelganger … guys do you hear me?" asked Barry.

"They can't hear you. I blocked all communications in the area including your suit" said Siren.

"Why?" asked Barry.

"Because, I have some news that you might want to hear Flash" said Siren

"And that is?" asked Barry.

"I overheard that when Zoom comes back he is going to kill your father." Said Siren.

"WHAT?" shouted Barry

"That's right, we he comes back he is going to kill your father. Unless" said Siren

"Unless what?" asked Barry

"You kill Zoom first." said Siren.

"I don't kill" replied Barry.

"Then how do you plan to stop Zoom? No prison can hold you or Zoom. Unless you have a place that could hold someone like you." Asked Siren.

"No" whispered Barry.

"We, both could go and kill him together." Suggested Siren.

"I thought that you worked for him?" asked Barry.

"You don't work for Zoom, you listen to Zoom." Retorted Siren.

Barry sat there and thought for a second 'I cannot lose my dad like I did my mom. And she is right, what prison can hold Zoom. He would get out eventually and we would be back to square room. I can't tell the team though … they would talk me out of it … and for good reason. Maybe I could … '

"So, what do you say?" asked Siren

"We can knock out Zoom and take his speed away. That way he would be stopped and would pay for his actions" replied Barry.

"Okay, I guess that works. Can you get us back to the other Earth?" asked Siren as she smashed the device to block his comms

"Of Course, hang on." Said Barry as he grabbed Siren and when through a breach into Earth 2.

"Barry Are you there? What happened to the comms? …" said Cisco.

(Star Labs)

Cisco was trying to contact Barry through the comms.

"Barry … Can you hear me? Barry?" Said Cisco.

"What happened? "Asked Joe

"I can't reach Barry on the comms." Said Cisco.

"I can't get his vitals either" said Caitlin.

"Where was he going?" asked Iris.

"He was going to stop a meta-human attacking Mercury Labs" said Cisco.

"Is the satellite out of range?" asked Harry.

"No, the satellite is always over Central City … and it is proper range." Said Cisco.

"Maybe, something is blocking it?" suggested Iris.

"Possibly, but why?" asked Caitlin.

"What powers did the meta human have?" asked Henry.

"We, do not know." Said Cisco.

"HOW COULD YOU NOT KNOW?" yelled Iris.

"We just got an alert that a Meta was attacking the labs." Said Cisco.

"Hang on, the vitals are coming back online." Said Caitlin.

"Barry Are you there? What happened to the comms? Did the Meta … "Started Cisco.

"Cisco, look." Said Caitlin with fear in her voice, when Cisco looked at the screen, he went wide-eyed.

"WHAT THE HELL IS GOING ON?" yelled Joe.

"Barry went through a breach … to Earth 2" said Cisco.

When Siren and Barry jumped through the breach, they were at Star Labs on Earth 2.

"Are you ready to stop Zoom?" asked Siren.

"Hang on … I need the machine to take Zoom's speed." Said Barry.

"How long will it take?" said Siren.

"15 minutes at most." Said Barry as he went to work on his machine.

(Star Labs Earth 1)

"Why would he go to Earth 2?" asked Henry.

"To stop Zoom, obviously." Replied Harry.

"But, why now? We have no way of holding Zoom" asked Caitlin.

"I have no idea. And plus, he is not even fast enough to beat Zoom." Said Cisco

"Why don't you try vibing him, Cisco?" Said Iris.

"Give me a sec" said Cisco.

Vibe

Cisco was in a hospital room with Barry and Laurel, Barry was wearing casual clothes and laurel was in the hospital bed.

"I'm glad you are awake." Said Barry.

"So, what happened while I was out?" asked Laurel.

"Basically, shit hit the fan. Literally, we at war right now." Said Barry.

"It's all my fault isn't it?" asked Laurel.

End Vibe

Cisco came out of the vibe.

"What did you see?" asked Joe.

"It was really weird … Barry and Laurel where in a hospital room. Barry was saying he is glad that she is awake. Barry said that they at war, Laurel thought it was her fault. "Said Cisco.

"But Laurel is dead. What war where they are talking about?" Said Caitlin.

"It is definitely the future." Argued Cisco

"I don't know, Laurel is dead." Said Caitlin

"Alternative timeline maybe?" suggested Cisco

"Then why would Barry be there?" asked Caitlin

"Who is Laurel?" asked Iris interrupting Cisco and Caitlin conversation.

"Laurel Lance, the former Black Canary. Damien Dark killed her with one of Arrow's arrows" said Cisco.

"Maybe, it is her Earth 2 doppelganger" suggested Harry.

"What do you know about her doppelganger?" asked Joe.

"Let's see" said Harry as he pulled up his file of Earth 2.

"She was a Lawyer for Central City. Two days before the accelerator explosion she was thought to have been kidnapped by the Merlyn Crime Family. Two days after the accelerator when off, Thomas Merlyn were found dead. Her body was found in the warehouse where Thomas Merlyn body was found." Said Harry.

"So, it is not your or our Laurel. Then where is she from? "Asked Joe.

(Star Labs Earth 2)

Barry had just finished the machine to take Zoom's speed, it was inspired from the machine that Harry used to take his speed.

"It's all done." Said Barry as he walked out of the lab.

"Good, let's go stop Zoom." Said Laurel.

Barry then picked up Laurel and zoomed just outside Zoom's lair.

"Ready?" asked Barry.

"Of course." Replied Laurel.

"You were stupid to come here Flash." Said Zoom.

Laurel used her Cry to keep Zoom in one place when Barry zoomed over and knocked him out.

"How do you know he will not wake up?" asked Laurel.

"I made a serum to keep him knocked out." Said Barry.

"How long will it take?" asked Laurel

"Not long." Said Barry as he walked towards the cells.

"What are you doing?" asked Laurel.

"Zoom had a guy trapped up here and I plan to let him go." Said Barry.

Barry opened to the door to the Man in the Iron mask cell and he walked out. Barry took off his mask.

"I'm the Flash from another Earth, Zoom is taking a nap in the other room." Said Barry as he proceeded to take off the mask from the prisoner.

"Thanks for freeing me, I am the original Jay Garrick from I believe you would call Earth 3" said Jay.

"No, Problem. I am going to take care of Zoom." Said Barry.

"What is that machine attached to his chest?" asked Jay.

"It is taking his speed away. "Said Barry.

"I got to get back to my Earth. I owe you one." Said Jay as he opened a breach and went back to Earth 3

"So why don't we talk?" asked Laurel

"Sure, why not." Said Barry.
