"Why haven't you returned to Star Labs yet?" Thawne asked over the comms, since the three of them had decided to just go to where they knew Firestorm was likely hiding.

"Cisco vibed this burning man's location. We're heading there to check it out." Barry said.

"I wouldn't recommend that considering what Caitlin and I have just discovered about the burning man." Thawne said.

"Okay, we're on our way back." Barry said as Cisco looked around before opening a breach back to Star labs, which the three of them went through it back to Star Labs.

"Hey, welcome back." Cisco said as he quickly kissed his girlfriend hello.

"Okay, so what did you discover?" Barry asked.

"This is footage from outside Star Labs at the time of the explosion." Caitlin said as she pulled up an image of a familiar face.

"Who is that?" Barry asked.

"That's Professor Stein." Jesse said and Thawne nodded.

"And the item he is holding is called the Firestorm matrix. Now, watch what happens when the dark matter wave hits him." Thawne said as they watched the wave of energy wash over Stein, but they noticed another face in the wave.

"Is that the face of the burning man?" Jesse asked.

"It wasn't easy, but we managed to get a facial ID. Jefferson Jackson. It looks as though the dark matter wave fused them and the firestorm matrix together." Caitlin said.

"And I believe that this may shed a new light on the attack victim." Thawne said.

"What do you mean?" Jesse asked.

"Quentin Quale is an old colleague of Martin Stein. It appears that while Jefferson's body is the one in play, Stein's mind is the one in control of this body." Thawne said.

"Simple darwinism, survival of the fittest." Barry said and Thawne nodded.

"However, I get the feeling that the two of them can't remain that way for much longer without something bad happening." Cisco said and Thawne nodded.

"I did some research on the firestorm matrix and I believe that the matrix will become unstable if it remains in its current state, it will build until it discharges." Thawne said.

"So we need to find a way to separate them." Jesse said.

"I might have something that can work." Cisco said.

"Your quantum splicer." Thawne said and Cisco nodded.

"It should bombard the organism's cells with enough energy to cause them to separate back into two individual people and negate the effects." Cisco said.

"Go get it. Caitlin, something tells me that you might need to prepare something to help them focus, since they're likely mentally unstable in this form." Thawne said.

"I'm sure I can whip something up." Caitlin agreed as she headed to her own lab to start working on that very thing.

It was decided that all four of them would go bring in Firestorm, which was why they were walking under the same bridge Firestorm had hid out in last time.

"Professor Stein. Are you here?" Jesse called out as they heard a noise to the left and saw Jax, looking much more rugged than they'd ever seen him before, approach them.

"Ms. Allen. You recognize me?" Firestorm asked and Jesse nodded.

"I do. And my friends and I, we think we can help you if you'll let us." Jesse said as Caitlin handed her the syringe with mental stability serum she'd whipped up and Jesse cautiously approached Firestorm.

"How?" Firestorm asked.

"First, we can help you calm down with this." Jesse said as she used her speed to quickly inject Firestorm with the serum and right as he flared up, Caitlin switched to Frost and cooled him down.

"Sorry about that Professor, but can't you think more clearly now?" Jesse asked.

"Yes, I can." Firestorm said.

"Professor Stein, my name is Cisco Ramon and I believe that this should be able to split you and Jefferson Jackson apart." Cisco said as he pulled out the quantum splicer.

"What is that?" Firestorm asked.

"It's a quantum splicer. It should theoretically allow you two to separate." Cisco said and Firestorm nodded.

"But, we should probably get you to a safe distance from the city before we activate it." Barry said and Firestorm nodded again.

"One step ahead of you." Cisco said as he opened the breach.

"What is that?" Firestorm asked.

"It's called a breach and it's the fastest way we can get you back to your old self." Barry said and Firestorm just nodded as he followed Jesse through it, since he figured if his student trusted them, then he could as well.

"Okay there, we should be safe now." Barry said as Cisco attached the splicer to Firestorm.

"What now?" Firestorm asked.

"Now the splicer should cause the matrix in you to expel enough energy to force you both to separate." Cisco said.

"And we should probably back up." Barry said as they saw the energy start to build.

"Good luck professor." Jesse said as they breached away as Firestorm blew up.
