Barry and the team at S.T.A.R. Labs work to capture Kyle Nimbus, a.k.a. The Mist, a dangerous new metahuman who can turn into poison gas and is going after the people who charged him with the death sentence. Upon realizing they’d need a prison to house the metahumans that are not killed in battle, they realize they could use the particle accelerator as a makeshift prison for people with powers. They revisit the painful night the particle accelerator exploded and killed Caitlin‘s fiancé, Ronnie; an engineer who helped build the machine, Ronnie singlehandedly recalibrated the blast so that it would go up instead of out, saving everyone at S.T.A.R. Labs, but died in the process. Meanwhile, Joe decides to finally visit Henry in jail after all these years, but things take a dangerous turn when Nimbus shows up looking to punish Joe for arresting him years ago. Barry is able to save Joe with an antidote, and eventually stops Nimbus by tiring him out, as he could only stay in his gas form for limited times. Meanwhile, Iris and Eddie reveal their relationship to Joe. Caitlin faces the particle accelerator again, and realizes it only reinforces her love for Ronnie as a hero rather than causing her more trauma, allowing her to be more open and happy again. In flashback, we learn that Dr. Wells had a video feed of Barry getting hit by the lightning the night the particle accelerator exploded.
