If you’ve been keeping up with The Flash then you know that things have gotten very interesting recently. The show is slowly but surely moving towards a story arc that will involve time travel and next week’s episode looks to progress that story in a big way.
Next week’s episode will deal with Firestorm and Barry’s revelation that he at some point goes back into the past in an attempt to save his mother.
