The first trailer for the back half of season 3 of The Flash has arrived. At the beginning of the year, Barry vowed to himself and his friends he would never change the past again but he never said anything about the future. After Barry saw a glimpse into the future where the speed god Savitar killed Iris in the midseason finale, he and Team Flash must figure out a way to stop that future from happening
The Flash returns Tuesday, January 24 at 8 p.m. ET/PT on The CW.
