"So, how exactly is this supposed to work?" Laurel asked as she and Thea joined the rest of the team in front of the thing that Wells had constructed.
"It's simple really. This machine will allow us to replicate the accident that turned Barry into a speedster in the first place, without creating another dark matter explosion." Harry said.
"Why are you 2 wearing your suits?" Cisco asked.
"Because we just came from stopping another attack. Ever since Zoom revealed to the city that the Flash is gone, more and more metas keep popping out of the woodwork." Thea said and Laurel nodded as Barry entered the room, wearing his Flash suit.
"Well not for much longer. Assuming this works, the Flash will be back in Central City soon." Barry said as he got into the machine and the clamps locked down on his wrists.
So Barry just gets in, we turn it on, and that's it?" Thea asked.
"Yeah. No. Not exactly. In addition to recreating what happened with the particle accelerator explosion, we also have to recreate what happened to Barry." Harry said.
"Getting struck by lightning." Joe said.
"That's right." harry said.
"Wait, so how are you gonna do that? It's not even raining outside." Laurel asked.
"Well, Ramon, you have the wand." Harry asked.
"The one I made for Mark Mardon?" Cisco asked.
"No, the one you built for the Harry Potter convention. Yes, of course, the one you built for Mardon." Harry said irritably.
"How do you know about the Harry Potter convention?" Cisco asked and Thea could resist a laugh.
"- Get the wand. Get on the roof." Harry said.
"- Why the roof?" Cisco asked.
"Because we're gonna need a lightning rod, and that, Ramon, is gonna be you." Harry explained and Cisco just nodded and did what he was told
"All right, I'm on the roof. Wow. I've never actually been up here before. I think I can see my apartment from here." Cisco said.
"Now head straight to the satellite, Ramon. When I give you the signal, you're gonna create a lightning storm above you." Harry said.
"So I'm just supposed to stand here in the middle - of a lightning storm?" Cisco said sarcastically.
"- Really, Ramon. Chances of being struck are slim, indeed." Harry protested.
"Yeah, not when you're the one causing it." Cisco countered.
"All we need is one lightning bolt to strike the satellite. The satellite circuitry is connected to the breach room. Barry's in the breach room. Just do it." Harry grumbled.
"Yeah. I'm doing it. Mozart better watch out. Cisco Ramon's about to conduct something nasty." Cisco said.
"You're gonna feel these clamps, but they're necessary." Harry said as the clamps locked down on Barry, who grunted.
"You good?" Joe asked.
"- Yeah. I'll be fine, Joe." Barry assured him.
"Barry, whatever happens, it will never change the way that I feel about you." Iris said, making Laurel and Thea think there was a story there.
"Son you don't have to do this if you don't want to." Henry said to his son.
"Being The Flash that's the best version of me. If I don't have my speed, I'll never be that person anymore. I have to do this." Barry pressed and both Laurel and Thea could relate to that, since that's exactly what Black Canary and Speedy were to them.
"Okay. You ready, Allen?" Harry asked and Barry nodded.
"All right, then. Here we go." Harry said as he activated the reaction.
"Ramon, get ready! I'm gonna release the chemicals into his system." Harry said.
After hearing metallic clicking and injectors moving to inject things into Barry, who grunted, Iris turned to Harry and asked "Why are you doing this?"
"The night Barry was struck by lightning, he was doing fingerprint analysis. Those chemicals got in his system then, and they are going in now." Harry explained.
"So you're injecting them into him?" Laurel asked.
"We have to recreate everything that happened to Barry that night." Harry countered.
"I'm okay, Iris!" Barry said at her concerned look as he started panting.
"- Hold on, Barry." Harry said.
"- God! - He's going hydrostatic." Henry said.
"- Almost there. Almost there." Harry said.
"- Wells!" Joe shouted.
"- Almost there. Ready, Ramon?" Harry asked.
"Ready!" Cisco shouted.
"- Now!" Harry shouted.
Cisco raised the wand to the storm that he'd created, and just like Harry Potter, he shouted "- Expecto Patronum!"
Lightning crackled as it struck the wand and Cisco looked on in amazement.
"Great Scott! It's working!" Cisco said.
"Initiating collision." Harry said as the accelerator went online and Barry was hit by the dark matter energy, but it actually began to destroy him.
"Barry!" Iris shouted as the blast cleared the safe zone and hit them, sending Thea flying backwards into a wall.
"Is everyone okay?" Joe asked.
"What happened?" Laurel asked as they noticed the empty space where Barry had been, only being filled with the emblem from his suit.
"No! No." Harry said.
"What did you do to my son?" Henry demanded as he turned to face Wells.
"Thea." Laurel shouted as she ran over to her.
"Henry, please, help me." Laurel begged and Henry nodded, deciding to temporarily suspend his anger at Wells to make sure Thea was okay.
"Her heart stopped beating and she has no pulse." Laurel said, tears coming to her eyes as she began chest compressions.
"There were strikes all over the building. Jesse, come down here, please." Harry said over the PA system, but to his alarm, there was no response.
"Jesse, Wally?" Harry asked as he looked at Joe and both fathers immediately ran upstairs.
"Oh, God, Wally! No, no! Wally! Wally, wake up! - No! - Can you hear me? - Wally!" Joe shouted as Wells did the same thing with Jesse.
"- Jesse, Jesse! - Jesse!" Wells shouted.
"Wally!" Joe shouted.
"Stop yelling, please." Wally grunted as he came to, but Wells began panicking.
"Her heart stopped. Her heart stopped! Jesse Are you okay? Jesse! - [gasps] - Oh [panting] It's beating. Her heart's beating." Wells said, sighing in relief after a moment as Iris approached them.
"How's Thea?" Joe asked.
"Her heart's beating again, so that's something." Iris said.
