Caitlin Snow missed her best friend, Jemma Simmons, they had met when Caitlin was four and was living in England with her mother. That was until her mother had to move back to the States when Caitlin was eight, though Caitlin and Jemma kept in contact through all the years they hadn't seen each other since Caitlin left, of course they included some photos every once in a while, but it wasn't the same.

Caitlin told Jemma about Barry Allen and the rest of the team, about all the good work that they were doing together, while Jemma did the same with Daisy Johnson and her team. A part of each of them (Caitlin and Jemma) wanted to run tests on those called meta-humans and inhumans when they first learned about them, but they also knew it didn't really matter as long as those with their power/gift were using those powers/gifts for good.

Caitlin was currently working at one of the Cortex's computers trying to figure out who this new meta-human was when she spotted a team of people entering Star Labs. She immediately notified Barry who said he was on his way and then she and the rest of the team went to meet the new comers.

"Who are you and what do you want?" Barry said as he flashed to be in between the new comers and the team.

"I'm looking for a friend." Jemma said as she noticed that Daisy had stepped in front of her blocking Barry from her. She watched as Barry stepped in front of Caitlin in the same matter.

"Jem?" Caitlin asked in shock.

"Cait!" Jemma practically shouted before racing to hug Caitlin, who embraced her immediately.

"I can't believe you're here!"

"I've missed you."

"I've missed you too."

"Cait?" Barry questioned.

"Barry this is Dr. Jemma Simmons, my best friend." Caitlin answered.

"Hey!" Cisco said a little hurt.

"Sorry Cisco. My first female best friend."

"Thank you."

"Jem." Daisy said wondering if this was a good idea to come here.

"Sorry guys. This is Dr. Caitlin Snow." Jemma replied.

"Sorry, not that this isn't great meeting new people and all, but who are you and what exactly do you need from us?" Cisco asked as Caitlin gave him a stern look. "What? No one ever stops by to just say hello."

"He is right Snow." H.R. said.

"You might want to introduce the rest of us first through. Joe said with his Dad voice.

"You're right Joe." Caitlin said and then pointed to each person as she introduced them. "This is Detective Joe West, his daughter Iris, his son Wally. This is H.R., Cisco, and this here is Barry Allen."

"It's nice to meet you all and put a face to the names." Jemma said and then introduced her team the same way that Caitlin did. "This is Director Coulson, Agents May, Mack, Yo-yo, Fitz, and this is Daisy Johnson."

"So you're Daisy." Caitlin said as she studied Daisy.

"Cait." Jemma said knowing that Caitlin was if Daisy was as special as Jemma made her.

"I'm not doing anything."

"Yes you are. She's different."

"Promise?"

"Promise. And It's not like I'm studying anyone."

"Only because you already did when he first entered."

"True."

"I've really missed you." Caitlin said pulling Jemma into another hug.

"Same here."

"We need your help." Director Coulson said stepping closer to the group. Before he took a step too close Barry was there blocking the way toward Caitlin.

"Bar it's okay. They are good guys. They won't hurt us." Caitlin said.

"Are you sure Cait?" Barry said still not sure he liked them being in Star Labs.

"You trust me, right?"

"Of course."

"Then trust me with this."

"Okay. How can we help?"

"Were looking for an inhuman, who can set himself on fire."

"Inhuman?" Iris questioned.

"I believe you call them meta-humans here." Jemma stated.

"People who have powers or gifts that aren't normal. Though inhumans are turned by Terrigan mist, while your meta-humans were turned by a particle accelerator explosion."

"The meta-human that sets themselves on fire? Is she talking about Ronnie and Professor Martin Stein or Jax and Stein?" Cisco asked.

"Ronnie? As in Ronnie Raymond?" Jemma asked.

"Long story Jem, but Ronnie was pulled into the singularity so it can't be him. And Jax and Martin are in a different time. I'm sure Sara would have told us if they were back in our time." Caitlin stated.

"Different time?" Mack asked.

"Another long story. Do you have any idea who they are or any physical characteristics we can search for?" Barry asked.

"Yes his name is David Jones. We believe that he is a meta-human, but he might be an inhuman. He can set himself on fire and can produce fire without warning. He was in this area when the particle accelerator exploded, but he might have been exposed to the Terrigan." Fitz stated.

"Cisco can you try and vibe him? See if you can find him?"

"Vibe?" May asked.

"I'm a meta-human. I have the ability to get vibes off of items and people. I also have the ability to open portals and send out vibrations. I can try to vibe him. Do you guys have anything of his? It helps to narrow down his location." Cisco relayed.

"Here this was his." Elena said holding out a shirt.

"Thanks."

"Why don't you guys come into the Cortex. Barry, Wally you guys want to get some extra chairs?" Caitlin said as Wally and Barry flashed away to grab the chairs.

"Wow they're fast." Daisy said as she watched them disappear and some of the hair was blown into messes.

"Barry and Wally are speedsters. Do any of you have a gift or power?"

"I kind of have Cisco's power with the vibrations, but my powers are still growing. They also call me Quake."

"I have a power similar to Barry and Wally's, but I have to come back to the spot that I left, which is why they call me Yo-yo. You guys can call me Elena." Elena said with a smile.

"Come on through this way." Caitlin said grabbing hold of Jemma's hand pulling her toward the Cortex, leaving everyone else to follow.

"So Barry's quite handsome." Jemma said leaning against Caitlin as they walked.

"He is. I also noticed that Daisy is quite beautiful."

"She is."

"How is Fitz taking it?"

"He's fine. He knows that I love, just not in the way that I love Daisy." Jemma said as they entered the Cortex and Cisco entered from the other end of the room.

"I've got a vibe on him. He's looking for Daisy. He's been tracking her movements." Cisco said as Barry and Wally had finished gathering all the chairs.

"Why would he be looking for Daisy?" May asked.

"Sorry vibes only tell me what he's doing not why." Cisco stated, "Also he's the meta that we've been looking for."

"How do you know that?" Joe asked.

"He was counting the money from the latest bank robbery."

"All right. That means we need to get him, but now we get to figure out who keeps him. What do you do with the inhumans you capture?" Barry asked Coulson.

"We have a containment facility. Do you have a containment place?"

"Several actually, but most of them we keep in the pipeline that we made in to a containment area. We have several metas there already."

Well if he's a meta and not an inhuman, which I believe that he is, you guys can keep him."

"Sounds good. Now for the difficult part. How do we capture him?"

"I believe if we work together we can handle him. Daisy you can throw him off balance, Barry and Wally can create a vacuum around him which will prevent him from creating fire. We have a gun that won't kill him, but will knock him out."

"You up for a run Wally?" Barry asked with a smile.

"Totally." Wally replied with a smile.

"All right. Gear up." Coulson said to his team.

"Time to suit up. Cisco you'll come to in case we need a breach."

"May, you and Elena will go. May you're our best shot."

"I'm in." May said.

"Three from each team sounds good. Cait will you please get them some monitors and coms." Barry asked Caitlin.

"Yep. These will monitor your vitals. Here are coms for you too." Caitlin said handing each person some devices.

"Thank you." Daisy said taking her devices.

"I can create you two suits that will monitor vitals and surrounding information with coms embedded." Cisco said, "I've created Barry's, Wally's, Jesse's, and a lot of the devices that we use for capturing metas."

"Cisco get your gear on." Iris said sharply.

"Okay, okay."

Once everyone was suited up or had their gear on they left for the last location that Cisco had for David Jones. Leaving the others to monitor the situation at Star Labs.

"Barry, Wally check the surrounding area. Make sure there's no hidden traps." Cisco said over the coms.

"Got it." Barry said as he flashed around the area with Wally. "There's some sort of device on the front door. Cisco you'll need to vibe them inside. Wally and I will phase in."

"On it." Cisco said taking a look at the location before opening a portal. "Go through here you'll be inside the building."

"Okay." Elena said with a nod from Daisy.

"Barry look out!" Wally called out as David Jones threw a fireball at Barry. "Cisco, guys he's not in the building."

"Where is he?" Daisy said getting ready to fight.

"Back of the building in an alley."

"Here this will take us behind the building and into the alley."

"Ahhh!" Barry called out being hit by several fireballs.

"Barry!" Caitlin cried into the coms. Jemma had taken her hand in hers in hopes to calm her down.

"I'm okay. Cait." Barry said sounding out of breath.

"We're here Barry." Cisco said quietly as he and the others appeared out of the portal behind David Jones who was facing Barry.

"Daisy you're up." Coulson said.

"You got it." Daisy said and quaked David off his feet. Barry and Wally flashed in circles around him preventing him from flaming up or firing fireballs.

"May do you have a shot?"

"I have the shot." May replied.

"Take it." Coulson said.

David Jones was suddenly struck and fell to the ground the bullet was absorbed by his body.

"Caitlin, Jemma get ready to test if this guy is inhuman or a meta. He should stay out for a few hours." Coulson stated to Caitlin and Jemma who got up and headed to the exam room that Barry and Wally were going to bring David to.

"Wally help me get him back to Star Labs. Cisco, you want to portal everyone back?" Barry said as he and Wally grabbed hold of David.

"Yep. I got them." Cisco said as he created a portal.

Back at Star Labs Jemma and Caitlin were gathering equipment that they would need to test David, while the others talked about different missions that they had worked on.

"Cait. How do you tell if it's a meta-human you're dealing with?" Jemma asked as they waiting for Barry and Wally to arrive with David.

"They have a certain about of radiation from the particle accelerator explosion and they have a change in their DNA and sometimes their blood." Caitlin said then asked, "How do you tell?"

"They have the terrigan mist DNA in them. Once they are exposed to the mist their DNA is changed and has certain genes included." Jemma replied.

"Here you guys go." Barry said as he and Wally dropped David on to the bed.

"I'll get the DNA sample and blood test sample." Caitlin said.

"I'll test for radiation or terrigan mist." Jemma said as she moved in the equipment.

Barry and Wally left the girls to do their work and joined all the others in the Cortex.

"Do they have the results yet?" Mack asked.

"No, they are just getting started." Barry stated.

"So how long have you known Caitlin?" Daisy asked Barry when they sat down next to each other, but all the others could hear their conversation.

"A few years. How long have you known Jemma?" Barry asked Daisy after answering her question.

"Same, few years. Caitlin a good person?"

"The best. Jemma?"

"Definitely the best."

"Are you two done seeing who's girlfriend is the best?" Cisco exclaimed. "What?"

"Barry, you are hopeless." Iris said.

"How do you know about Jemma and I?" Daisy asked a little surprised.

"When we first met you stepped in front of her when you thought there was a threat. You also were holding her hand when she went to join Caitlin to test David." Barry said.

"Well you're not too subtle yourself. You did the same thing when we met. But you kept your eyes on her when she went to check David too."

"Caitlin and I aren't dating."

"And why is that?" Cisco said.

"Because you don't want her to get hurt because of what you do." Daisy stated.

"Yes." Barry replied.

"Well you're an idiot. She loves you. And you both deserve to be happy." Iris said from her spot next to Wally and Joe, on the other side of the room.

"Iris."

"Barry I've been your best friend since we were kids. You've loved her since you met. And she has become my friend, she deserves to be happy."

"Who deserves to be happy?" Caitlin asked as she and Jemma entered the room.

"Everyone. Everyone deserves to be happy." Barry practically shouted and got pointed looks from everyone in the room, even May. "So is he a meta or an inhuman?"

"Meta looks like he's staying with us."

"Okay, I'll go put him in the pipeline." Wally said as he flashed into the exam room and then to the pipeline.

"You okay Barry?" Caitlin asked putting a hand on Barry's shoulder that was a little charred from David.

"Yeah, yeah I'm good." Barry stated.

"Did you get hit anywhere else with his fireball?"

"No, but I'm all healed.

"Let me double check."

"Cait I'm good."

"Don't care."

"Okay."

Caitlin then led Barry to the medical room leaving everyone else to talk about what to do to get Barry to talk to Caitlin about the way that he felt for her.

"So has he finally admitted he's in love with her?" Jemma asked everyone.

"How do you know he loves her?" Iris asked.

"From the way that he looks at her. And they way he stepped in front of her when we first arrived."

"He won't tell her." Daisy mentioned.

"Because of the whole hero's don't get the girl things?" Jemma asked.

"Yep."

"Let me talk with him." Joe said, "He normally will listen to me about this type of stuff."

"Are you sure Dad?" Iris asked.

"Yeah. I'll get him to talk to her."

At that moment Barry and Caitlin came out of the medical room only for Joe to pull Barry aside and they took a walk out of the Cortex for a moment.

"So you guys talking about anything interesting?" Caitlin asked as she took a seat by Cisco and Jemma.

"Nope, nothing interesting, just talking about the weather it's pretty nice outside right now." Cisco said quickly.

"When do you guys have to leave?" Caitlin asked turning to Jemma.

"I'm not sure, Director?" Jemma asked Coulson.

"After a few days we will need to get back to base. I'd like to see a little more of what you guys do here and I'm sure we could share some of what we've learned." Coulson said.

"We should have dinner on the roof." Barry said with a smile as he and Joe entered the room again.

"On the roof?" Caitlin asked.

"Yes on the roof. I have actually set up a few tables and chairs up there with a grill. We always eat here in the Cortex and I figured it'd be nice to eat outside sometimes."

"That's sweet Barry."

"Caitlin do you mind if I talk to you for a minute?" Barry asked as Caitlin moved to stand.

"Sure." Caitlin said as she followed Barry into the hall that he and Joe had entered from.

"I wish I could be there for this." Jemma said, only to get looks from everyone, "What? She's my best friend and he's finally going to tell her he loves her. It's my job to want the best for her."

"Well now that you mention it. We have camera's all over Star Labs with listening capabilities." Cisco said pulling up where Barry had taken Caitlin too. Soon that computer was surrounded by both teams wanting to hear what was going on.

"Are you okay Barry?" Caitlin asked as she watched Barry pace for a moment.

"Yeah. I'm good. I just…" Barry stopped for a moment before continuing. "Caitlin we're good friends right?"

"Of course, the best."

"Remember when we were talking in the hall after capturing Peek-a-boo?"

"Yes."

"When I said that we had been hung up on people for too long and you said that it was time to move on and be crazy about someone new. Well I think we were right. You deserve to be happy, we both do. Caitlin, I like you a lot. I think you feel the same way and I want you to know that whatever happens in the future. I want you by my side." Barry said as he grabbed hold of Caitlin's hands.

"Barry." Caitlin said squeezing his hands to get his attention. "I love you too."

"Really?"

"Yes really. Now shut up and kiss me."

Barry didn't need to be told twice, he leaned down and kissed her. In the back ground they both could hear the cheering going on in the Cortex and laughed (after their kiss of course). Barry picked Caitlin up in to his arms and flashed to the Cortex, where their new friends and old friends congratulated them.

The next few days both teams worked together on different projects, helping and guiding, to lead to completed projects. Cisco of course made suits for Daisy and Elena, who loved them. Jemma and Caitlin promised that they would keep in touch with each other and that if either team ever needed help the other team would be there. Barry finally took Caitlin on a private date that she deserved and after they took a long walk around the shoreline.
