Take a look at this jam-packed trailer for the third season of The Flash. This trailer was first seen at Comic Con 2016. It’s looking like we’ll see Barry alter the main timeline of the show – saving his mother from being killed when he was a child, but at the same time changing his relationship with Iris, Cisco, Joe, and pretty much everyone else in his life. Iris doesn’t seem to know Barry. Neither does Joe West. Cisco Ramon is “the richest man in America”. Plenty of quick cuts of characters both good and evil blast by in this trailer, including Zoom and Grodd, among others. Oh, and it looks like this show’s Wally West fulfills his destiny as a speedster, wearing what appears to be “Kid Flash” gear.
