Ep 19. Back to Normal

Barry Allen wakes up and finds that he's not The Flash anymore. In fact, he's just an ordinary man with no powers living in Central City. He discovers that the particle accelerator explosion from years back has caused him to lose his speed, and therefore his superhero abilities.

He tries to adjust to his new life, but it's hard for him to go back to a life without The Flash. His friends are supportive, but they can't help him in this situation. Caitlin Snow, in particular, tries to find a way to help him get his powers back.

Meanwhile, a new metahuman villain named Griffin Grey (played by Haig Sutherland) appears on the scene. This villain has the ability to age at an accelerated rate, and he's on the hunt for a cure. He doesn't want to die because of his condition, so he kidnaps Caitlin in order to force her to help him.

Barry has to figure out a way to stop this villain without his powers. He ends up making a deal with Harry Wells from Earth Two, who agrees to help him take down Griffin Grey. Together, they come up with a plan to stop the villain and save Caitlin.

Throughout the episode, we see Barry struggle with his loss of powers. He's used to being The Flash and using his speed to save people, but now he has to go back to being an ordinary person. He realizes that he took his powers for granted and that being a superhero is not just about having abilities, but also about having the desire to do good.

The episode ends with Barry accepting his new reality and trying to find a way to move forward. He knows that he can't be The Flash without his powers, but he's still determined to help people in any way he can.

Overall, "Back to Normal" is a compelling episode that explores the idea of losing something you thought you couldn't live without. It takes a break from the usual superhero action and focuses on the characters and their relationships. The episode also introduces a new and interesting villain in Griffin Grey, who poses a unique challenge for Barry and his team.
