Iris volunteers to act as the bait in a plan to trap Girder (Greg Finley) in S.T.A.R. Labs; Barry struggles to go back to his old life.

Barry is back in his mother's arms. But if Joe isn't Joe, then it's more than likely this isn't Nora Allen, either. Is Barry trapped inside the speed force? And what makes it so different?

Barry looks very confused. If he's confused, imagine how we'll be as this all plays out. Who cares? An emotional Barry is always gripping!

Assuming this isn't Nora, what sage advice will she have to give the man who isn't her son? It's going to be a long wait for Tuesday!
What are the odds we will cry at least once during these scenes between Barry and probably-not-Nora?

This is the scene after which the episode is named, "The Runaway Dinosaur." It must have been a book Barry liked as a child.
