The Flash gets a bit surreal this week, but then, with the title of “The Runaway Dinosaur,” it wasn’t going to be one of their more normal episodes. The STAR team is trying to figure out what happened when Barry suddenly disappeared when they get another surprise. After Jessie and Wally don’t answer the intercom, Wells and the Wests find Wally and Jessie on the floor of the hallway. Wally comes around, but Jessie is out cold and initially even her heart seems to have stopped. Henry, after he’s shaken off the shock of Barry’s vanishing, agrees to use his medical training to check her out. Cisco uses his powers to figure out Barry is still alive, but trapped in some weird energy vortex.
