"Barry." Joe said as he entered Barry's crime lab.
"Hey Joe, what's up?" Barry asked.
"I was hoping you could talk to Iris for me." Joe said.
"Why don't you just talk to her?" Barry asked.
"I would except she's not answering my calls." Joe said.
"What do you want me to talk to her about?" Barry asked.
"Try and talk her out of enrolling in the police academy." Joe said.
"Why? She wants to be a cop, I don't see why not. She certainly has the talent." Barry said as he absently continued his work.
"Barry, I want her to be safe. Being a cop does not fall under that criteria." Joe said.
"Well, Iris isn't a little kid anymore. She's a grown woman who can make her own choices. And besides Joe, she's your kid, she's got your morals and your drive to help people." Barry said.
"So, that's a no." Joe said.
"Yeah, that's a no. Joe, you can't control Iris forever. I get that you want her to be safe, but at the same time, we both know her well enough to know that you trying to get her to not do something is just going to want to make her do it more." Barry said and Joe had to give him that.
"While I acknowledge that, I still don't want her anywhere near this live, especially after what happened with Clyde Mardon." Joe said.
"What happened?" Barry asked, playing dumb.
Joe looked around before saying "I saw something impossible. The only reason I'm telling you is because you're one of the few people who believes in the impossible." Joe said.
"So, what did you see?" Barry asked.
"I saw Mardon generate a tornado with his bare hands. And then I saw 2 other people, a man and a woman, both of them run faster than the speed of sound." Joe said.
"Really, sound familiar?" Barry asked.
"Barry for the last time, there was no one inside your house that night." Joe said, right as Eddie walked in.
"Eddie, good timing, what's going on?" Barry said.
"We just got a call from Mercury Labs. Someone tried breaking into a secure vault and 2 security guards were killed." Eddie said.
"Let me grab a few things." Barry said and Eddie and Joe nodded as they left his lab and Barry called Caitlin.
"Barry, what's up?" Caitlin asked.
"Wells made a move for the tachyon device at Mercury Labs. Something tells me we're going need both Killer Frost and Firestorm for this." Barry said.
"Copy that, I will let Stein know." Caitlin said as Barry hung up and after grabbing some stuff from his lab, headed out.
"What are you thinking?" Joe asked Barry as he did his thing.
"The blood splatter patterns and trajectory of the remains only a high-speed collision could have done this. But to cause this type of damage to a human in this space?" Barry said.
"Whatever hit them would have to have been moving fast." Joe said and Barry nodded as Eddie approached them.
"Get this. The witness says all he saw was a blur." Eddie said, getting Barry's attention as he and Joe went up to the witness.
"You saw a blur? W What was it?" Barry asked, needing to know if his suspicions were confirmed.
"Whatever it was, it was looking for something." the scientist said.
"Well, what did it look like?" Joe asked.
"Like a-a man in some kind of yellow suit." the scientist said.
"Okay. Thank you." Joe said as he and Barry moved away and he could already tell Barry was preparing to move into an I told you so speech.
"I told you Joe. I told you. The man in the yellow suit, he's real. This proves it was not my imagination." Barry said.
"Okay, you've made your point. You were right and I was wrong. Your father is innocent." Joe said and Barry nodded triumphantly.
"You can apologize later, right now, we need to figure out how to catch this guy." Barry said and Joe nodded as he noticed Barry beginning to leave.
"Where you going?" Joe asked.
"Star Labs. I've been spending time there since I came out of my coma so they can test me for any delayed effects of the lightning bolt. They might have some ideas." Barry said and Joe nodded, fully accepting that answer.
"So, wait a minute, the man in yellow is back." Iris asked as Barry told them all what happened.
"The witness described seeing a yellow blur just like the one that killed my mom." Barry confirmed.
"Then we need to get cracking and stop this speed psycho. That I wasn't trying to give him a name." Cisco said.
"The crime scene at Mercury Labs was on a floor with highly secured vaults, and the witness said he was looking for something." Barry said.
"Whatever it was, he wanted it badly enough to kill for it." Wells said.
"Doctor, what do you know about this Mercury Labs?" Stein asked.
"Mercury was one of S.T.A.R. Labs' major competitors until our little setback, and then it catapulted to the forefront led by Dr. Christina McGee, brilliant but egocentric physicist." Wells said.
"Says here Dr. McGee has secured half a billion dollars in private funding to develop, and I quote, "prototypes for the technology of the future."" Cisco said.
"Well, I'll be. Tina's messing with tachyons, superluminal particles." Wels said as he looked into some Mercury's projects.
"Wait, couldn't tachyons be used to make one be able run even faster than Mr. Allen or Ms. West?" Stein asked and Wells nodded.
"We need to get what Mercury has to use as bait." Barry said.
"Something tells me Dr. McGee won't exactly be willing to hand over one of her leading projects to a competitor that could just easily take credit for it." Iris said.
"I'll see if I can get Joe to get us a warrant." Barry said.
"Perhaps it would be easier to convince Detective West if we were to bring him into the fold." Wells said.
"No way. My dad is insanely overprotective, he's still mad at me for joining the police academy again, but this time, I'm not backing down. If he knew that I was a speedster, he'd never let me out of his sight, which could put him in more danger." Iris said.
"I understand that Iris, truly, I do, but right now, I don't think we have a choice if we want to convince your father to help us catch this guy." Wells said and Iris could tell she was outvoted.
"Fine." Iris said and before anyone could stop her, she sped off and returned a moment later, depositing her father in the middle of the cortex.
"What the hell was that?" Joe asked as he looked around.
"That was me showing you my super speed dad." Iris said bluntly.
"Wait, Iris, you're?" Joe asked.
"Speedstress." Iris said as she vibrated her hand.
