Barry Allen's (Grant Gustin) time line woes are far from over. The Flash will turn back the clock one more in episode 17, and his trip down memory lane will bring him in contact with Hartley Rathaway (Andy Mientus).

After photos surfaced of Mientus filming an apparent shot for shot recreation of a scene from season 1's "The Sound and the Fury." we did a little digging.

"Hartley Rathaway, aka Pied Piper, the arrogant former protege of Harrison Wells and employee at S.T.A.R. Labs who lost his hearing when the Particle Accelerator exploded, returns to wreak havoc once again on his former colleagues when the Flash impossibly revisits an earlier timeline," The CW told EnStars on Tuesday.

The episode will be appropriate titled "Flash Back."

Gustin and Danielle Panabaker (Caitlin) both recently took to Twitter to tease the upcoming episode, informing fans that it will elicit both tears and laughter.
