After Barry brought Kara up to speed on Grodd, they headed to Star Labs.

"So what's going on?" Kara asked.

"Before the accelerator exploded, Star Labs had a government contract with the military to try and awaken soldier's latent mental capabilities in battle." Caitlin said.

"What we didn't know, is that the military General Wade Eiling was trying to create super soldiers with telepathic and telekinetic abilities." Cisco said.

"Sounds like he'd get along really well with Lois's father and maybe even Project Cadmus." Kara said.

"Anyways, Grodd was one of the test subjects who was subjected to Eiling's cruel experiments until Thawne shut down the project." Caitlin said.

"What happened to him?" Barry asked, even though he already knew.

"We're not sure. After the accelerator exploded, I went to check on him and he was gone." Caitlin said.

"And how do you know that he's back now?" Kara asked.

"Because I've been looking for him ever since. I've been using a tracking algorithm with the Star Labs satellite to try and find him. Now I'm starting to think that Thawne let him go as part of a future plan that never happened because we trapped him in the Speed Force. I recently got a hit and thanks to Iris's investigations online, I think I might have a lead on him." Cisco said.

"Do you think he's looking for Thawne?" Barry asked.

"I mean it would make sense. Thawne always seemed to have a special bond with Grodd." Caitlin said.

"What sort of powers would Grodd have?" Kara asked.

"I'm betting that the dark matter wave released by the particle accelerator somehow activated all the crazy serums that Eiling injected Grodd with, not only giving him psychic powers, but also allowing him to achieve sentience." Cisco said.

"Great, so I'm going to head to the DEO." Kara said.

"What, why?" Barry asked.

"Because they've dealt with telepathic aliens before, so I'm going to see if J'onn would be willing to let us borrow any anti telepathy technology they have for this." Kara said and Barry nodded, since that was a good idea.

"We'll keep trying to track down Grodd." Barry said and Kara nodded as she flew out of the lab.

"So Cisco, why did you want to see us?" Ronnie asked as he and Stein entered Cisco's workshop.

"Well for one thing, Ronnie remember Grodd?" Cisco asked.

"Oh yeah, Caitlin loved that big guy." Ronnie said.

"I'm sorry, who's Grodd?" Stein asked.

"A test gorilla from a previous experiment. Turns out the accelerator explosion turned him into a meta gorilla." Cisco said.

"You're kidding." Ronnie said.

"I wish. We're pretty sure that the serums Eiling injected Grodd with were activated by the dark matter wave and it gave Grodd sentience, an extremely advanced intellect and telepathic abilities. Kara's at the DEO now to see if J'onn will let us borrow some of their anti telepathy tech to protect us from Grodd's mind control." Cisco said.

"Surprised you're not just building it." Ronnie said.

"Oh believe me if we had more time, I would, but this is faster. Anyways, while Kara does that, I figured now would be a good time to test out something else I'm working on." Cisco said.

"And that is?" Stein asked.

"This." Cisco said as he held a blue vial.

"What's this?" Ronnie asked.

"A way to safely transfer the entire stabilized firestorm matrix into one body." Cisco said.

"Wait seriously, this could make it possible for me to be a solo firestorm?" Ronnie asked, since he and Stein had both agreed that while they made a good team, they couldn't keep this up forever, especially given the professor's advanced age.

"Yep." Cisco said.

"So how does it work?" Stein asked.

"It's simple, Ronnie drinks this and then you will have to merge one more time." Cisco said.

"Why?" Ronnie asked.

"Because that's the only time the matrix is whole. You'll need to remain merged until the matrix has fully stabilized into Ronnie's body. At that point in time, you two will split automatically, Professor Stein, you will be completely human again and Ronnie, you'll be a solo firestorm." Cisco said.

"How long will the transfer take?" Stein asked.

"No idea. Never done this before." Cisco said.

"I think we should wait until after Grodd is dealt with, just for safety reasons, but then, I'm game for taking this cure if you are." Ronnie said to Stein.

"Agreed. Thank you Mr. Ramon." Stein said.

"My pleasure." Cisco said with a smile.
