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 (Andy Mientus), as well as old friend Eddie Thawne.
Iris (Candice Patton) makes peace with her past in order to embrace her future.
