Adelia sat at the desk, watching in amusement as Barry sped between a game of ping pong with Cisco, Operation with Caitlin, Chess with Dr. wells, and Uno with herself. They were testing Barry's multi-tasking abilities, a training activity Adelia had done many times. Barry stopped at the desk, looked at his cards, and dropped a red two on top of the pile.

"Uno." he said, and put the card back on the desk, before going back to his other games.

"This isn't even remotely anatomically correct." Caitlin complained, as Adelia dropped a card onto the pile.

"That's not the point, Dr. Snow." Barry said, and quickly took his turn then returned to ping pong.

"Then what is the point?" she asked.

"To have fun." Barry answered.

"And to continue your ongoing training by testing the speed of your mind by pushing your ability to multitask." Dr. Wells said, and Barry sped over to take his turn.

Barry went back to playing ping pong for a few seconds, before speeding over to Adelia, sighing at the draw four card that Adelia had placed.

"How many of those do you have?" he asked, then was gone again.

"None." she replied, dropping a seven down as Cisco missed the ball.

"Checkmate." Dr. wells said, causing Barry to speed over, while Cisco retrieved the ping pong ball.

"Wait, checkmate?" he asked.

"Checkmate." Wells replied. "I guess we still have a few things left to learn, don't we, Mr. Allen?"

An alarm began beeping. "Armed robbery at 4th and Collins." Cisco said. Adelia set her cards down, and was gone in a moment.

"For the record, I crushed it at Operation, Ping Pong, and Uno." Barry said.

Adelia arrived at the crime scene and took out a couple of the criminals before Barry even got there. One of them shot the driver of the truck that was being robbed.

"Where's the nearest hospital?" Barry asked.

"St. Andrews." Caitlin answered. "Seven blocks north, two east."

"Call the ER, tell them they have an incoming GSW." Barry said. The whirring of motors alerted both speedsters as the criminals began speeding away from the scene on their motorcycles. Adelia ran after them, but one of them seemed to be ready for this, taking out his gun and shooting it at her. She easily dodged the bullets, but ended up tripping in the process, and rolled into the grass on the side of the road. By the time she was back on her feet, they were gone.

"And this is where my team monitors the police bands for criminal activity." Adelia looked up as she heard Barry's voice. Walking in with him was an unfamiliar woman with blonde hair. "We can track anything that's happening in the city. Check this out. We've got our own satellite."

"I know." the woman responded. "I've hacked into it from time to time."

"Rude." Cisco said as he and Caitlin walked towards the two. Adelia stood a few feet back, confused as to what was going on.

"It is, of course, so wonderful to see you again Felicity." Caitlin said. "I'm just wondering how much of our operation she needs to know about."

"I am really good at keeping secrets." the woman, Felicity, said.

"Yeah, Felicity works with the Arrow." Barry said, pointing at her.

"Sweet." Cisco said.

"And you apparently are not." Felicity stated, looking at Barry.

"Now it's all making sense, you know who the Arrow is." Cisco said.

"Hold on." Adelia said. "I'm sorry, who's this, and why does everybody, but me, know her?"

"Oh, right. This is Felicity." Caitlin said. "We met her while you were in the coma. Felicity, this is my sister Adelia."

"Nice to meet you." Felicity said as Dr. Wells came in.

"Welcome, Ms. Smoak." he said.

"Dr. Wells?" Felicity said. "The Dr. Wells?"

"Please, call me Harrison, Felicity." Wells said.

"Oh, you know who I am?" Felicity asked.

"Ranked second in the National Informative Technology competition at age 19, graduated M.I.T. with Masters Degree in Cyber Security and Computer Sciences. I know who you are. I keep an eye out for promising talent in scientific fields. It's what brought me Cisco, Caitlin, Adelia, and I foresaw great things from you."

"Speaking of great things." Barry said, drawing Felicity's attention back to him. "Want to see something cool?"

Minutes later, Barry was on the treadmill, running, while the rest of the team and Felicity watched from the other side of the glass.

"How fast can he run?" Felicity asked.

"He hasn't even reached his top speed yet." Dr. Wells replied. "Theoretically speaking."

"So, is he really okay?" Felicity asked.

"His heart is within normal heart range for him." Caitlin answered.

"No, I mean, the lightning bolt changed him." Felicity said. "Do any of you know how much?"

"We know a fair amount." Cisco answered.

"If everything about him his sped up, is he going to age faster?" Felicity asked. "What would happen if he ran too fast? I mean, would he just be running, and then, poof, he's dust in a red costume?"

All eyes turned on Wells, and he said, "Everything we do here at S.T.A.R. Labs is to protect Barry Allen. Trust us, Felicity, he's in very good hands here."

"Wanna see how fast I can run backwards?" Barry yelled suddenly from the other side of the glass.

"Barry, that's not-" Adelia was cut off as Barry crashed into the wall behind. "-a good idea."

"Don't worry." Caitlin told Felicity. "He heals quickly, too."

"How long has it been missing?" Dr. Wells asked Cisco, who had just made the discovery that some weapon, one he made in case Barry turned out to be a bad person, had gone missing.

"I don't know." Cisco answered, staring into the empty storage space where the weapon had been.

"I'm going to ask you again, Cisco." Wells said. "But when I do, I expect a more specific answer than I don't know. Now, how long has this weapon been gone?"

"A day, maybe two." Cisco answered. "One of the janitors didn't show up for work this morning. He was probably the one who took it. I didn't think that-"

Dr. Wells slammed the door of the spot where the weapon had been held, and said angrily, "You didn't think, because if you had, you would have discussed with me first your desire to build something that could, in theory, hurt someone, and in particular Barry and Adelia."

"I'm sorry." Cisco said slowly. "If you would just let me explain-"

"You know how I feel about weapons, Cisco." Dr. Wells said. "They do not belong in S.T.A.R. Labs. Now, you are going to figure out a way to locate this gun. And you are gonna do it right now."

Once he finished talking, he turned and wheeled out of the room.

"This thing you built, what can it do?" Caitlin asked.

"Bad stuff." Cisco answered vaguely.

Barry sped into S.T.A.R. Labs. "Snart was spotted downtown." he said.

"Who's that?" Caitlin asked.

"Oh, um, one of the robbers from earlier." he answered.

"Okay." Adelia said, getting to her feet. "Let's go."

Once they arrived on scene, Barry immediately had to push Joe out of the way of some blast, and it instead hit Barry.

"You okay?" Joe asked Barry.

"It burns." Barry answered. Adelia noticed a thin layer of ice had formed over Barry's torso where he'd been hit with the blast.

"Hey, Cisco?" she asked.

"Yeah?"

"What did your weapon do again?"

"Why?"

"Because I think we just found it." Adelia answered, as Leonard Snart shot the weapon at her, she quickly ducked behind a pillar. "Snart has it."

There was a brief pause, then Cisco said, "Don't let it hit you."

"No, I thought it was going to be fun to get hit by an anti-speedster weapon." she said.

"Time for a test run." she heard Snart say. Adelia ran out as she heard the gun fire, and moved a couple out of the way as Snart fired at them. Barry was speeding around to get others out of shooting range, and then Snart shot at a man who was in the doorway of a theater. Adelia sped in the direction, and moved the man out of the way, but not before the blast hit herself.

"It's still numb." Barry said once they were back in S.T.A.R. Labs.

"It's presenting itself like third degree frostbite." Caitlin said.

"I thought he had hyper-healing?" Felicity asked.

"It's been slowed." Caitlin responded. "If your cells weren't regenerating at the rate they are, your blood vessels would have frozen solid, and the nerve damage would have been permanent. You're both lucky to be alive."

"Snart wasn't another meta-human." Barry said as he stood up and began to pace around the Cortex. "He had some kind of gun. It froze things, slowed me down."

"According to his record, Snart didn't even bother to finish high school, so how did he manage to build a hand held high tech snow machine?" Felicity asked.

"S.T.A.R. Labs built the cold gun." Dr. Wells answered.

"They didn't have anything to do with this." Cisco said. "I built the gun."

"You did?" Barry asked. "Why?"

"Because speed and cold are opposites." Cisco replied. "Temperature is measured by how quickly the atoms of something are oscillating. The faster they are, the hotter it is, and when things are cold, they're slower on the atomic level. When there's no movement at all, it's called-"

"Absolute zero." Barry cut Cisco off.

"Yeah." Cisco said. "I designed a compact cryo engine to achieve absolute zero. I built it to stop you. I-I didn't know who you were then, Barry. I mean, what if you turned out to be some psycho, like Mardon or Nimbus?"

"But I didn't?" Barry asked angrily. "Did I?"

"We built the entire structure you're standing in to do good, and it blew up." Caitlin said. "In the wake of that, you can understand why Cisco would want to be prepared for the worst."

"I can understand that, but what I can't understand is why you didn't tell me what you did." Barry said. "I mean, after all we've been through, I thought you trusted me. I thought we were friends."

"We are, Barry." Cisco said.

"I mean, if you would have just told me, I could have been prepared." Barry said. "But instead, somebody could have died tonight."

Cisco nodded. "I know."

"Do you?" Barry asked, and walked out.

"I figure out a way to stop Captain Cold." Cisco said as he walked into a Cortex with a tablet in hand. Adelia looked at him.

"Really?" she asked.

"You gotta stop naming these guys." Caitlin said.

"Barry, listen to him." Dr. Wells instructed. Barry reluctantly turned to face Cisco.

"How?" he asked.

"The cold gun is powered by an engine control unit, a microcomputer that regulates air to fuel ratios so the sub-cooled fluid in the chambers don't overflow and-"

"Explode." Felicity said, cutting off Cisco, who turned around and pointed at her.

"Right." he said, before walking around to the desk. "This E.C.U. was receiving updates wirelessly from my tablet. If I boost the signal using Central City's network and send a false update, we'll get a ping back, and then-"

"We can locate Snart." Wells said.

"How long will it take?" Barry asked.

"Uh, first I have to hack into the city's network, so, I don't know, thirty minutes, maybe?" Cisco said.

"I can do it in less than one." Felicity volunteered, going to one of the computers. "When it comes to hacking, I'm the fastest woman alive." She cracked her fingers. "Ugh, that was not as badass as I pictured. Alright, I'm in."

"Are you kidding?" Caitlin asked.

"Alright, I'm sending the updates." Cisco said. "We're connected."

"Network is triangulating the location." Felicity said.

"We got him." Caitlin said. "He's heading west on Nelson toward the train station."

"If he's leaving, it appears Mr. Snart may have gotten what he came for." Dr. Wells said. Barry quickly changed into his suit.

"When we put our minds to it, nothing can stop us, dude." Cisco said, then Barry turned his comms off. "Oh, you turned your ear piece off. How are we gonna talk to each other?"

"I don't feel like talking right now." Barry answered, then he was gone.

"Such an idiot." Adelia muttered, before she and her suit were gone too.

She followed him onto the train Snart was on.

"There's nowhere to run." Barry said, and Snart pointed the cold gun at them.

"I didn't see you before." Snart said. "Your mom know you're out past your bedtime?"

"If you wanted to get away, you should have taken something faster with a train." Barry said.

"That's if I wanted to get away." Snart said.

"Meaning?" Adelia asked.

"I've seen your weakness at the armored car, then at the theater. See, while you're busy saving everybody, I'll be saving myself." Snart said, then pointed the cold gun at the floor, and fired it. Then the train began to shake and the lights flickered. Passengers began to scream, and Snart pried the doors to the train open. "Good luck with that!" he yelled, the jumped out of the door. The train began to topple off of the tracks, and Adelia raced forward, grabbing passengers and speeding them off of the train, and Barry began to do the same. Adelia landed in the grass after all the passengers were off the train, Barry not far from her.

She heard the sound off the cold gun firing, then she felt it hit her torso. She rolled onto her back with a grimace of pain, and saw Snart with his gun up. "You're pretty fast." he said. "But not fast enough. Thank you."

"For what?" Barry asked.

"You forced me to up my game." Snart answered. "Not only with this gun, but with how I think about the job. It's been educational."

"Drop it." Cisco said from behind Snart. Snart turned his head to look at him, but kept his gun pointed towards Barry and Adelia. With Cisco was Caitlin and Felicity. "This is a prototype cold gun, four times the size, four times the power."

"I was wondering who you were talking to." Snart said, looking back at Barry and Adelia.

"Hey, unless you want a taste of your own medicine, I'd back the hell up." Cisco said.

"Your hands are shaking, you've never killed anyone." Snart said.

"There's a first time for everything, Captain Cold." Cisco said, and adjusted the gun in hand. "I will shoot you."

"You win, kid." Snart said, lowering the gun. "I'll see you around."

He turned to walk away, but Cisco said, "Hey, leave the diamond."

"Don't push your luck." Snart said.

Once Snart was gone, the gun was turned off, Cisco shook his head. "Couldn't shoot him if I wanted to." he said, with a small laugh. "This is actually the S.T.A.R. Labs vacuum cleaner with a lot of LEDs."

Caitlin and Felicity pulled the two speedsters to their feet. "Let's get you warm." Felicity said.

"Thank you." Barry said.

"We've been trying to track Snart, but he must have disconnected the signal somehow." Cisco said.

"We'll find him, Cisco, somehow." Barry said.

"You have a great team here, Barry." Felicity said. "Speaking of teams, I should probably get back to mine."

"It was nice meeting you, Ms. Smoak." Dr. Wells said. "Please extend a hello to the Arrow for us."

"I will." Felicity said.

"Goodbye, Felicity." Barry said.

"Bye, Barry." Felicity said, and the two hugged before Felicity left.
