Ep 20. Rupture

As Barry continues to deal with the aftermath of his decision to travel back in time and save his mother's life, a new villain named Rupture arrives in Central City. Rupture, a meta-human from Earth-2 with the ability to create sharp shockwaves, is seeking revenge on Cisco for the death of his brother, Reverb. Meanwhile, Barry and the team face a moral dilemma when they discover that Rupture is in fact a police officer on his own Earth, who has been manipulated into becoming a villain by Zoom. As they struggle to find a way to stop Rupture without causing more harm, Barry realizes that he must confront his own mistakes and learn to forgive himself in order to move forward. With the help of Cisco and the rest of the team, Barry manages to take down Rupture and come to terms with the consequences of his actions. But as Zoom continues to lurk in the shadows, it becomes clear that Central City is far from safe and that Barry's journey as The Flash is far from over.
