Caitlin worked for S.T.A.R. Labs, and was tasked with performing an inventory of a Starling City warehouse belonging to S.T.A.R. Labs, along with Cisco. Deathstroke showed up to the warehouse, and Caitlin mentioned an energy gun designed by Arthur Light that they could use to stop him. Cisco and Caitlin reported the incident to Felicity Smoak and John Diggle. Caitlin was visibly angry at Felicity for knowing who that man was. Felicity later showed up to Cisco and Caitlin, asking them to make a Miracle cure.
Caitlin was engaged to Ronnie Raymond before his disappearance, and she acted as the S.T.A.R. Labs resident chemist and analyzed Metahuman samples. During the first season, she was reunited with Raymond, but he sacrificed himself shortly after.
After Ronnie's death, Caitlin began to form a romantic relationship with Jay Garrick, whom she tried to help regain his access to the Speed Force. In order to do this she developed the chemicals Velocity-9 through Velocity-11, which could only give him speed for a limited time. As it turned out, Garrick was really the villain Zoom, and he kidnapped Caitlin and took her to Earth-2, where she formed a shaky alliance with her counterpart Killer Frost. The two nearly escaped Zoom's prison, but they were caught and Killer Frost was killed and Caitlin was taken to the Central City Police Department as a captive. She eventually talked Zoom into allowing her to leave, and she then resumed her place at S.T.A.R. Labs, and helped The Flash take Zoom down.
During what became known as "Flashpoint" Flash rewrote history, and when he tried to put it back together, Caitlin gained ice-centric Metahuman abilities, which she tried her best to hide from her colleagues. She had to briefly abandon her secrecy to rescue the Flash, who had become trapped in a mirror by Mirror Master. While no one saw her do it, her friends became aware of an ice-based entity somewhere in their midst. After saving Barry, her powers began to manifest physically in the form of whitening hair and blue lips, and grew in potency, as became apparent when she froze the water in her shower by mere proximity. She briefly turned rogue while trying to find a way to reverse her powers, embracing her self-hatred and briefly calling herself Killer Frost. After Barry Allen dared her to try and kill him unarmed, Caitlin snapped out of her anger and tried to keep her powers in check with a power dampener. She then tried to renounce the Killer Frost powers, but was encouraged to learn how to control them by Martin Stein.
