While this was a plenty entertaining episode, in a Back to lớn the Future sort of way, I sit here afterward thinking that in the end, not very much happened. Which isn’t a horrible thing. Maybe the show is simply so good with those last-minute “stings” that when it doesn’t deliver one, there’s an emptiness.

With everyone (Joe included) beating themselves up over the Zoom/Jay Garrick reveal, Barry is committed more than ever to lớn upping his speed. But, Caitlin asks, “What if you just can’t?,” after they realize that Zoom & Reverse-Flash before him ran faster because their feet made less contact with the ground. Dinner with the Wests proves fruitful, though, when Wally gives Barry the idea khổng lồ pick the brain of a dead man — as in the old Dr. Wells (aka Eobard Thawne).

After KOing himself with a tranq art, Barry goes to lớn S.T.A.R. Labs và nudges Wells to lớn help him out with a tốc độ equation. Wells obviously senses something is up, especially when a speedster-hating Time Wraith surfaces in Central City. Wells then KOs our Barry & locks him up, asking what his game is. At first, Wells/Thawne fears that if Barry is alive in the future, then his plan fails, so he must re-calibrate. But Barry lies that Eobard is successful in getting back to lớn his time — “You won.” Barry just needs more speed in order to lớn stop the singularity that was created. Evil Eobard points out that he doesn’t need this Barry và goes in for the kill, but Barry bluffs that he left a hidden letter for his other self to find, revealing all of Eobard’s secrets. Smart boy.

Shortly after the

Time Wraith storms S.T.A.R. Labs (only to get briefly fended off by the Pied Piper’s gauntlet tech), the other Barry comes to & shows up — face to face with his slightly older self, và leaving Cisco’s jaw on the floor. After some quarrelling over who the “real” Barry is, Wells steps in to spin a version of the truth that sates everyone’s curiosity. Wells then takes our Barry aside to give him the info he needs on the tốc độ equation. (But before going, Barry whispers into Cisco’s ear about Hartley knowing where Ronnie is.)

With help from his other self, Barry zips back into the time tunnel & brings the Wraith with him. Upon plopping back in S.T.A.R.

But afterward, Barry reveals something else he brought back with him — the đoạn phim he asked a still-alive Eddie to record, allegedly for Iris’ birthday video. In it, Eddie gushes about his love’s “fearless, independent, loving & kind” ways, calling every day they were together “a gift.” He then says what Barry sensed Iris needs to lớn hear now, that “you deserve to be happy for the rest of your life,” as tears stream down her & our faces.
