It doesnt matter if you win by an inch or a mile.
But that doesnt mean, win or lose, that race cant have major, life-altering implications.
With Henrys death looming over him, it wouldnt be a total shock to see Barry reach that point.

Hes a hurricane of emotion with one target on his mind Zoom.
He wants a plan to stop him without giving into the darkness Zoom so desperately wants to consume Barry.
Hes not willing to let his prey off easy, either.
Zoom threatens Barry that hes willing to take more from him unless… they race?
Yes, Zoom can kill with ease.
What he really wants is to prove hes faster than Barry, and so he wants to race Barry.
Should the scarlet speedster win, Zoom promises to leave them alone.
If he doesnt agree to these terms?
Well, then Zoom will continue to pick off his family one by one.
Barry sees no choice but to race Zoom.
But Joe can tell theres more lurking beneath Barrys decision he wants to kill Zoom, too.
Barry openly admits to that being a possibility.
When he awakes, he finds the entire team gathered to explain themselves.
Hes too angry and too willing to let Zoom determine the terms to have a hope of winning.
NEXT: Run, Barry, run!
Then, the group strikes.
The situation only worsens as Wally appears, now aware of Barrys secret identity after the last episode.
When Zoom gained his powers, he easily took control of Earth-2 but craved more.
Creating Velocity 9, he propelled himself to other universes, only to slowly kill himself in the process.
So he needed another speedsters power because even attempting to manipulate the Speed Force proved impossible.
Zoom discovered this poor soul on another Earth but couldnt take his speed.
Then, as he tells it, the clouds parted and he discovered Barry.
For now, he keeps this man as a trophy, just like he plans to do with Barry.
But this man in the mask proved useful in one respect, as Zoom stole his name Jay Garrick.
He frees Barry while the others are occupied, also freeing Barrys furor in the process.
Revenge will only get Barry so far, and the team worries it wont be far enough.
But Barry knows theyre running out of time and convinces the rest of the group to help him.
They return to the site of the magnetar, Zooms planned multiverse-destroying gadget, and Zoom quickly follows.
In true villain form, he reveals his master plan he wants to destroy everywhere but this Earth.
Zoom gives the team a moment to say their goodbyes, but they all refuse to leave Barrys side.
So the race begins.
The machine needs a certain amount of power to run, charged by their race.
But theyre not a fan club.
Theyre the thing that will ensure Barry wins because he has something greater to fight for than Zoom does.
The remnant is creating its own pulse to counterbalance that one and does so successfully.
Yet it requires the remnant to kill himself in the process.
Barry finally subdues Zoom; his hand quivers with the threat of death above his foe.
Zoom knows Barry doesnt have the gall to kill him now just like he didnt earlier.
NEXT: Barry makes a life-changing decision.
The day is won, but that victory comes with some powerfully conflicted emotions.
Hes a speedster from Earth-3 who suits up yet again, but his appearance freaks Barry out.
But as Joe acknowledges to him, this guy doesnt know hes the spitting image of Barrys dad.
It wasnt originally the real Jays, but it stood for hope on Earth-2 according to Harry.
Even with their world, and really all worlds, saved, Barry is still not at peace.
He feels like hes lost even though they just won, and thats because he has.
Barry wants to fix whats wrong with him, to find some sense of peace.
And just as Barry waited for Iris, Iris promises to wait for Barry.
Whenever hes ready, shell be here for him.
With a kiss and the two telling one another they love each other, she leaves him alone.
He runs, runs, runs to the starting point of everything for him his mothers death.
Whatever that means, Barry pays it little attention.
He instead turns to his mother and tells her shes safe now.
And she may be safe, but what of the rest of Earth or the other Earths?
Barrys decision will certainly have major ramifications when the show returns.
Does this world reboot itself, and if so, for how long?
