Finally, "The Flash" Season 3, Episode 1, "Flashpoint" has finally arrived. After Barry Allen (Grant Gustin) time traveled, he made a lot of major changes in his life and his friends' life.

After a long time of waiting, finally, "The Flash" Season 3 has been aired on Tuesday night, Oct. 4. Episode 1: "Flashpoint." The latest episode showed what happened next after Barry time traveled and changed the timeline.

In the new timeline, Wally West (Keiynan Lonsdale) is The Flash, but Barry called him as Kid Flash. Barry put Reverse-Flash (Matt Letscher) in a glass box. Back in the last episode of Season 2, Barry traveled back in time where his mom murdered, stopping Reverse-Flash for killing his mom.

Barry still has his power or speed, however, due to the changes he made, there are memories that gradually disappear. Cisco Ramon (Carlos Valdes) is a CEO of the giant company in the new timeline, while Caitlin Snow (Danielle Panabaker) is an optamologist.

Barry is helping the Kid Flash to capture The Rival. After he used his power, some memories disappear. So he asked the Reverse-Flash why some memories were lost. Reverse-Flash said, because Barry is using his powers, memories disappear.

Barry and Wally teamed up to capture The Rival, who also has speed like them. During the fight, Wally was stabbed by The Rival. Barry was able to beat The Rival, and revealed to Joe West (Jesse L. Martin) that he is The Flash and Wally is the Kid Flash.

Due to the tragedy, Barry decided to free the Reverse-Flash and allow him to fix the timeline, which means, allow Reverse-Flash to his mom. Barry was able to go back to the original timeline, however, (this is the ending), Joe and Iris West (Candice Patton) are not in good terms.
