Canon
Caitlin Snow is an intelligent and resourceful woman, who works as a bioengineer at S.T.A.R. Labs, where she first meets fellow scientist Ronnie Raymond. Ronnie is an adventurous contrast to the more structured and logical Dr. Snow and the two soon fall in love, and eventually become engaged. When the particle accelerator explodes, Ronnie risks his life to save everyone else and Caitlin thinks she loses him forever.

After rescuring Barry Allen, he and Caitlin quickly develop a close friendship, bonding over losing loved ones and the mission they have created with The Flash. Their relationship is very intense and there are hints and indications that they could develop into something more. This has yet to develop on the series.

Through their ex-colleague Hartley Rathaway, the team learn that Ronnie is actually alive – now as Firestorm with Dr. Martin Stein. After separating the two, Ronnie and Caitlin reunite shortly, before discovering that Firestorm's rising temperature will lead to a nuclear explosion. Thinking she will again lose him forever when Ronnie sacrifises himself yet again, Caitlin is awestruck to discover that Ronnie and Stein survive. Ronnie suggests they leave town and start anew, but Caitlin wishes to stay on with her mission with The Flash – and Barry.

Ronnie and Stein go away to figure out their new common identity and goal, and return to help Central City fight new foes. Ronnie re-proposes to Caitlin, who accepts and the two marry. Sadly Ronnie is lost when trying to close a portal opened in Central City to new dimensions.
