Canon
PRE-META Caitlin and Cisco meet for the first time in S.T.A.R. Labs when Cisco is hired in January 2013. Cisco is given a tour by Hartley Rathaway, who immediately feels threatened by Cisco and establishes an acrimonious relationship with him, in spite of Cisco's friendly demeanour. Caitlin remarks casually that Hartley seems to have met his match in Cisco's brilliance and introduces herself. Cisco eyes follow Caitlin as she leaves the room. He smiles and comments on how nice she is. They like one another immediately and become fast friends, along with Caitlin's boyfriend (and later fiancé) Ronnie Raymond. The three of them become really close friends and work together with "Harrison Wells" on the particle accelerator. In December they are ready to launch, but something fails and causes an explosion, which kills Ronnie as he tries to stop it.

Following the catastrophe and its effects on Central City, all the employees leave S.T.A.R. Labs with only Caitlin and Cisco remaining with "Dr. Wells", who is now in a wheelchair. Caitlin and Cisco are there for each other as they mourn Ronnie, and a few weeks later Wells brings Barry Allen to the labs for the three of them to care for as he suffers a coma as a result of the explosion. They meet Felicity Smoak, who comes to visit Barry in January 2014. In April, Caitlin and Cisco are tasked with taking inventory of their S.T.A.R. Labs facility in Starling City, after Starling cancels the lease on the building. Cisco tries to remind Caitlin that the explosion was an accident, but she is still suffering from the pain of losing Ronnie.

They are attacked by Slade Wilson and narrowly manage to escape with the help of Cisco's handling of a weapon designed by Arthur Light who was fired by Wells in Spring 2012 for making crazy things. Felicity and Diggle go to the scene and meet a shaken Caitlin and Cisco, who won't reveal what Slade took as they don't know that Felicity and Diggle actually work for Green Arrow.

Season 1
Cisco and Caitlin join Team Flash as Barry decides to become a masked hero to protect Central City. When Caitlin discovers Ronnie might be alive she goes to Cisco. Something Caitlin will continue to do throughout the series, showing how close their bond is. Cisco and Caitlin investigate finding “The Burning Man” a.k.a Ronnie. Cisco holds Caitlin as she cries over Ronnie being someone she no longer recognizes. The intimacy between them shows how much Cisco cares for Caitlin.

When Caitlin is taken by Captain Cold. Cisco is extremely concerned and he rescues her, along with Joe, letting her know he will never let anything happen to her. Cisco feels guilty about Ronnie’s death the night of the particle accelerator explosion and he opens up to Caitlin, who eases his burden, letting know it isn’t his fault. They later giggle and share ice cream together in a nice moment between them. When Cisco is abducted Caitlin is worried about him. It mirrors his concern for her when she was abducted. When Cisco is saved, Caitlin is overjoyed.

Similarly, again later in the season Cisco gets into a few scrapes, when stung by meta bees, Caitlin is worried and runs over to him. Again, when almost attacked by Bates, Caitlin runs over to Cisco to make sure he's okay.

Season 2
Cisco continues to be the main support for Caitlin as she mourns the loss of Ronnie. Their friendship continues to go from strength to strength, as they assist in Team Flash to help save Central City. Cisco observes Caitlin's bond with Jay and comments on it the most. Meanwhile he himself starts a budding relationship but it ends as quickly as it started. Unfortunately for Caitlin, it turns out Jay is actually Zoom and he betrays her. Barry finds out that Caitlin helped "Jay" with the Speed drug and is angry. Cisco jumps to Caitlin's defense and the team quickly move on from the incident. Cisco is Caitlin's rock as she deals with first "Jay's" death and then his betrayal. Cisco is the only one incredibly concerned about Caitlin's possible future as Killer Frost. He worries about it when travelling to Earth-2. He pleads with Earth-2 Killer Frost and insists that he shares a bond with her. Ultimately, she betrays Zoom, no doubt because of the conversations she had with Cisco who seemed to believe in her redemption. Also when she finds out about Jay's betrayal and is kidnapped, Cisco is frantic as Zoom carries her out the Lab. Cisco helps Caitlin deal with the trauma of being kidnapped. In a tender moment she leans on him for support.

Season 3
When Flashpoint causes Caitlin's powers to emerge, she is not sure who to turn to. Cisco is the person that Caitlin confides in. He is concerned about her and wants to keep her safe. So he semi-reveals to the Team her predicament. In Episode 5 Caitlin goes to visit her mother in an attempt to learn about Killer Frost. The team takes her absence in stride, however Cisco, knowing Caitlin so well, can sense something is wrong. They share a private moment in the speed lab, where Caitlin tells Cisco that Star Labs is home. When Killer Frost is unleashed Cisco is worried and very upset with Barry over Flashpoint. He gets into an argument with Barry where he aggressively pokes him blaming him for what is happening to Caitlin. It is evident how deeply he cares for Caitlin. When all is resolved and Caitlin is back to normal. Cisco watches her like a hawk. He always checks whether meta bracelet is working. Caitlin pouts telling Cisco they are running out of battery and aren't very handy. Caitlin is later presented with a necklace to dampen her powers which she happily receives. Caitlin helps Cisco deal with the death of his brother. When Savitar tricks the team, Cisco believes he can get his brother back and is willing to use his powers to do so. Caitlin talks him down by reminding him of their connection and reality. She is a comfort to him which allows him to defeat Savitar's control.

As she talks him down she reminds him of the times he helped her when she was struggling. Constantly through the show Cisco and Caitlin are able to get through to one another and share things which they don't share with anybody else. Cisco eventually comes to accept his brother's death and spends the second half of the season being consumed with trying to save Caitlin from turning into Killer Frost. He and Julian, who she is dating, clash over what is best for her and how to help her. Cisco is rather snappy with Julian who seems to believe he knows what's best. Whereas as Cisco being her long time best friend and confidant is grappling with what he believes will help Caitlin the most. Caitlin "dies" and Cisco wishes to respect her wishes of not turning into Killer Frost. Julian disagrees and rips off the necklace to revive Caitlin. Also the prophecy suggests that Cisco will have to destroy Killer Frost as he's the only one that can stop her. This scares Cisco as he says he doesn't want to hurt her.
