Between flashes of his alternate self, and a brief heart to heart with Detective West thanks to Barry tampering with the timeline, Wally appears to be cracking under the pressure. A chilling appearance from the villain Dr. Alchemy ends the trailer as he threatens the Flash, saying, "You have no idea what's about to begin."
