Episode 17 of The Flash season two is called “Flash Back” and it looks downright intense and freaky. It also looks like the name of the episode probably inspired the plot – well, it’s too good a pun not to use. If you’re watching at UK pace and wondering whether to risk watching it, we’ve just seen episode 13, and we reckon this trailer is only moderately spoilery – it doesn’t seem to give away any major revelations in between. Like Barry losing an arm or Iris growing a beard or something. But it does feature the return of a familiar character or two…
Here’s the official synopsis (with a massive spoiler removed): “Desperate to find a way to increase his speed, Barry decides to travel back in time and masquerade as his earlier self in order to get his arch-nemesis, Dr Harrison Wells/Eobard Thawne (Tom Cavanagh), to teach him how to run faster. However, things don’t go as planned and Barry is stunned to face familiar foe Hartley Rathaway (guest star Andy Mientus), as well as old friend Eddie Thawne (guest star Rick Cosnett). Iris (Candice Patton) makes peace with her past in order to embrace her future.”
It’s directed by Alice Troughton who did a few Tennant Doctor Whos a while back.
