“	Sometimes the only way to move forward is to revisit the things in your past that were holding you back. You have to deal with them head on, no matter how scary they may be. Because once we do, you'll see that you can go further than you ever imagined.	”
— Barry Allen^[src]

After the shocking revelation that Zoom is Jay Garrick, Barry is more determined than ever to get back to Earth-2 to stop Zoom forever. 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 nemesis, Dr. Harrison Wells/Eobard Thawne, to teach him how to run faster. However, things don't go as planned and Barry is stunned to face familiar foe Hartley Rathaway, old friend Eddie Thawne, as well as the real danger of time travel.
