Central City

Barry and Cisco were back in the hospital as Cisco was about to open the breach.

"You ready, buddy?" Barry asked.

"Yeah. You've always believed in me. Thank you." Cisco said.

"You got this." Barry assured.

Cisco put on his goggles and reached out, opening the breach as Zoom jumped out and Cisco ran off.

"Reverb's doppelganger has increased his powers." Zoom said.

"Hatred is a strong motivator." Barry sneered.

"You were unwise to reopen the breach." Zoom gloated.

"I'm not gonna let you terrorize another world anymore." Barry said.

"Without your speed, you won't be able to stop me." Zoom said smugly.

"Let's see." Barry said.

Zoom started to chase Barry but thanks to Thawne's tachyon enhancer Barry was faster before they entered S.T.A.R. Labs.

"Ah, you've gotten faster. Good. There'll be more for me to take." Zoom said gleefully.

"You want my speed? Catch me." Barry taunted.

Zoom chased Barry into the training room but to no avail before a cutout popped out, with a face of a woman that clearly brought Zoom uncomfortable flashbacks. Zoom tried to catch up with Barry again before another cutout popped out, with a face of Harrison Wells as Zoom stopped and glared hatefully. But that stop was his mistake. Barry knocked Zoom down and shot him in the leg with the Boot, the brace restraining Zoom's leg to the floor.

Zoom took off his mask as he faced Barry. "How did you figure out who I am?"

"Cisco's vibes." Barry explained and Zoom nodded, while noticing the disgust in Barry's face.

"It must be irritating, for another one of your enemies wear the face of someone close to you, huh?" Zoom said smugly.

"You're going to pay for what you've done. For what you did to the innocent on Earth-2, Jay, all of them." Barry vowed.

"It's not over yet, Barry." Zoom gloated before vibrating his hand and smashing the brace before he sped off. Barry attempted to follow him before he growled in frustration as Zoom got away.

"Barry, we have a problem." Cisco called out.

"What is it?" Barry asked.

"Joe called me. Zoom took Wally. He's gonna kill him unless you give Zoom your speed." Cisco said.

Earth-2

"Help! Somebody, please, help!" Wally called out, chained up in a cage in Zoom's lair as Zoom sped in and Wally paled.

"There's only one person who can help you now. The Flash." Zoom said ominously.

"The Flash? Why would he help me? He doesn't even know who I am." Wally said, confused.

Zoom laughed. "You're confused. But these two words should help you understand. Barry. Allen."

Wally stared, confused before suddenly, all the pieces fell together and his eyes widened in realization. Barry's constant running off, him being busy as CSI… it all made sense now.

Wests' house, Earth-1

Joe was in his room, sitting down in despair as Barry neared him. "Barry, I know you... can't give up your speed to that monster, but... I also know that I want to get my son back, and I don't know what to do."

"I do. Wally, he's... he's part of the family. He's... he's a part of... our family. And we do whatever we have to to keep the ones we care about safe." Barry said.

"No, you... you can't give up your speed." Joe protested.

"That's not your decision. This is the only way, Joe." Barry said.

Later, S.T.A.R. Labs

"Are you sure about this?" Cisco asked.

"I'm sure." Barry nodded, taking the Velocity-9 serum. Cisco touched it and vibed Zoom.

Cisco was in Zoom's lair as Zoom turned around, sensing him. "Zoom." Cisco called out.

"Vibe." Zoom growled, turning around.

"He'll do it. Barry will give you your speed." Cisco said.

They waited in the Cortex as Zoom sped in, with all of them aiming their weapons at him.

"Where's Wally?" Joe demanded.

"We had a deal." Zoom growled. "Give me the Flash's speed and I'll let your son go, Detective West."

"I want to see him." Joe insisted.

Zoom then sped in with Wally, who was held by Killer Frost, who had an ice dagger to his neck as Barry and Cisco stared. "You're supposed to be…"

"…dead?" Killer Frost smirked.

"I knew you'd try to reach her, she's been playing you all the time." Zoom gloated before he took off his mask and everyone, especially, Barry, Patty, Joe and Iris had shocked reactions. "I know. Handsome. Right? It's kind of ironic, when I steal my doppelganger's ancestor's face."

"My speed for Wally's life. Hand him over and it's yours." Barry said.

"You don't get to make any demands here. Give me your speed or Wally dies." Zoom warned.

"Barry, don't give him anything—" Wally shut up, when Frost neared an ice dagger to his neck.

"Shut up. If you want to keep breathing." Frost warned.

"Give me your speed or Wally dies." Zoom said.

"Fine. You win." Barry gave in as he and Harry got to work, while Harry glared at Zoom.

"How did you survive?" Harry questioned.

"Barely. By the thread." Zoom explained. "When I woke up, I was in the middle of the street. Confused. Not understanding what was happening to me."

Years ago, Earth-2

Hunter Zolomon woke up with burns all over his body as he got up, groaning, wondering what was going on. He then suddenly ran in superspeed as his hands vibrated, wondering what was going on. "What the…"

Hunter kept on running, confused until he fell down and faced a woman, who had pale skin and stark white hair, her hands freezing.

Present, S.T.A.R. Labs, Earth-1

"Frost nursed me to health. We were outcasts, shunned by society, none of the people appreciating our genius. So we decided to show them we're superior than them. That's why metahumans became outlawed on Earth-2." Zoom said. "But I couldn't fix my face. Until I saw poor Eddie flying in through the hole in the sky. And let me tell you, how could you not like him? Handsome?" He gestured at his face as everyone, especially, Barry, Iris, Joe and Patty glared at the insane speedster in disgust.

"Your lightning is blue. A speedster on this Earth used Velocity-9 and her lightning turned from yellow to blue until she faded into nothing." Patty said.

"Oh, that." Zoom chuckled. "Well, Velocity-9 was a project I had been working on before I was fired. And of course, Garrick, a fellow scientist, wanted to use any advantage he could to beat me but neither one of us knew the side effects until it was too late. And he lost his speed during our fight, when the Singularity happened and that's when I saw you and found out an opportunity for a cure."

"Who's the man in the iron mask?" Barry demanded.

Zoom smirked. "You wouldn't believe me, if I told you."

"I'll give you my speed. And you let Wally go."

"No! Not for me, Barry!" Wally protested as Frost neared the dagger to his neck.

"One more word and I'll cut out your voice box." Frost growled.

"It's OK, Wally." Barry assured.

Harry and Barry followed Zoom as Harry glared at Zoom. "One day… I'm gonna knock that smug expression off your face."

"Barry—" Joe started.

"It's alright, Joe." Barry assured.

Barry ran on the treadmill as it was draining him of the Speed Force as it ended up in a vial as Barry slowed down normally.

"He's slowing down." Caitlin said.

"The Speed Force is leaving his body." Harry said.

"He's becoming human again." Cisco said as Barry's Speed Force was in a vial, while he fell down in exhaustion, panting out.

"Barry. You OK?" Patty asked, helping him get up.

"I'm OK. I'm OK." Barry assured.

Zoom put the vial into an injection pistol and injected himself with the Speed Force, laughing crazily as everyone stared at him in shock, while he eyed them all, his insanity on full display. "It would be so easy for me…" He disarmed them all of their weapons in superspeed before he sped behind Patty, who paled as he grabbed her by her neck. "…to kill you all before either one of you…" He got in front of Iris, his claws touching her chest as she gulped. "…before you could blink. But no." He then eyed them all. "I win. Where's the fun in killing you all? No. You will all live, knowing that I'm faster than anyone of you and there is nothing you can do to stop me. It would be easy for me to kill you all. But seeing all your beaten faces is even more satisfying.

Like I told you, I am the fastest man alive. Not you. Don't bother trying to come after me. There is nothing you can do to beat me… if there is no Flash to help you. Goodbye."

Everyone stared in despair as Zoom and Frost sped off, knowing there was nothing they could do to take them down without Barry's speed.

Honestly, Zoom's plan made sense up until the point he returned Wally back to Earth-1. At that point he had no leverage over Team Flash and they had no reason to give him Barry's speed anymore, they had the perfect opportunity to take him down, once Zoom handed Wally over before he would take Barry's speed. Plot over logic.

Plus, as pointed out in Stand's story "The other side of the mirror", which can be found on AO3, why would Zoom not tell Wally who is Barry, if he had the chance to screw with him? Again, plot over logic.

The only reason Zoom didn't kill or kidnap anyone here, is because he's so insane he believes it's more satisfying to be the only speedster alive, enjoying for them to know that they have lost forever, completely broken.

So, what do you guys think?
