With Joe (Jesse Martin) finally behind Barry’s (Grant Gustin) new “job” with the S.T.A.R. Labs team, Barry finally settled into his new role as the Flash in episode 2 of “The Flash” on the CW. However, episode 3 would test the new superhero against his deadliest foe yet – the Mist.

Things got going in the new episode when an entire crime family was killed by poisonous gas during a secret meeting. Joe and Barry investigated the crime scene where they determined that the murders could only have been committed by another meta-human capable of controlling airborne substances.

While Joe and Barry searched for their new enemy, the S.T.A.R. Labs team began to devise a plan to hold meta-humans that they capture. Harrison (Tom Cavanagh) realized that the now out of use particle accelerator could be turned into a makeshift prison that could disable meta-humans’ powers. However, returning to the particle accelerator inspired some flashbacks from the S.T.A.R. Labs team revealing how Caitlin’s fiancé, Ronnie (Robbie Amell), died helping to contain the blast.

Back at the station Barry, with help from Caitlin (Danielle Panabaker), worked on identifying the poisonous gas used to kill the crime finally. When no gas was found in the dead bodies’ lungs, Barry deduced that the meta-human they were looking for did not control gas, but became it. Just then, Barry was alerted to another gas attack at a shopping mall and sprung into action.

At the mall, Barry came face-to-face with deadly new meta-human (Anthony Carrigan), which Cisco (Carlos Valdes) dubbed the Mist. Barry tried to stop him, but was poisoned in the process. Barry made it back to S.T.A.R. Labs where the team was able to get him breathing again. Harrison did manage to get a sample of the gas in the process.

Studying the gas, the team discovered it contained a sedative compound given to inmates on death row before being executed. After searching for inmates who were executed the night of the particle accelerator explosion, the team discovered that Kyle Nimbus, a member of the crime family that was killed earlier in the episode, was the identity of the Mist. The people he had been killing had been those responsible for putting him away (the lawyer in the mall and a rat at the meeting). The only person left on his list was the lead detective on the case – Joe.

Barry got to Joe just in time. The Mist had poisoned Joe right after the detective met with Barry’s father (John Wesley Shipp). In front of his father, Barry gives Joe an antidote that Caitlin reverse engineered from the poison. Barry then went after the Mist himself.

Outside Barry was able to keep the Mist in gas form long enough to wear him out, allowing Barry to take him down. The Mist became the first prisoner in the S.T.A.R. Labs prison.

The major reveal in the episode, though, came after, when in one last flashback the show revealed that Harrison seemed to know Barry would be struck by the blast the night of the particle accelerator explosion. Did Harrison choose Barry? Fans will have to tune in next week to find out.
