The CW/Warner Brothers released season 3 trailer of The Flash, which picks up after the events of the season 2 finale, wherein Barry Allen had travelled back in time to save his mother from the Reverse Flash aka Eobard Thawne.

The promo opens with Barry saving his mother from the Reverse Flash, with actor Grant Gustin saying, "There is only one thing I know about life. I know some things happen by chance, and some things happen because we make them happen."

After this the timeline sort of collapsed and the events of season 1 and 2 are erased. Fans are then introduced to the new Flashpoint universe. In this timeline, Barry is happily living with his parents, Nora and Henry Allen. "I am finally free, I'm home," says Barry. Then we are introduced to Iris West, Cisco Ramon and Joe West and in this timeline, they are not a crime fighting team.

Barry and Iris run into each other at Jitters, where the latter questions, "You look very familiar, I have seen you before... Haven't I?" Following this, he introduces himself as Barry Allen to her and they share a moment.

Looks like Barry and Iris will be friends, or even more than that in this Flashpoint timeline, as the speedster says, "Some people are just meant to be in your life."

Amid all the developments, Barry suddenly gets a headache and sees the word "Alchemy" written on a glass, and finds himself at the Star Labs facility, but in this timeline it is called Ramon Industries, owned by Cisco – who is now the richest man in America. Barry reaches out to Cisco and Joe West, who turn him down (as they do not remember him), but it is Iris who believes in him.

Meanwhile, the Reverse Flash, who is seen in captivity in a cell, says, "This isn't your home Barry. It's a mirage, it's already screwing with you and everyone you love and pretty soon it's going to take me right down along with you."

"What should we call this brave new world that you whipped up for us? I was thinking Flashpoint" remarks Thawne, as we are introduced to new villains, Kid Flash aka Wally West. The promo ends on an interesting note, as Thawne calls Barry a villain. "Now who's the villain Flash? Now who's the villain?" yells the Reverse Flash, as we see Barry simply walking away from him.

Is Barry the new villain? He did put the whole world in jeopardy and whipped out a new timeline just to be with his family, but does this make him a villain? We will let fans decide when The Flash returns with season 3 on 4 October on The CW Network.
