Barry thinks he is ready to fight Zoom.
Barry is definitely not ready to fight Zoom.
And for that bullheaded thinking, Barry receives a crippling injury.

Zoom doesnt show up simply for kicks, though.
Barry wants to lure Zoom to their world, and he believes Dr. Light will be the perfect bait.
Luckily, theres someone else who can wear it, since Dr. Light has an Earth-1 twin.
So the disparate parts of the plan coalesce.
Barry still wants to send his emblem through to the other side, forcing Zooms hand.
Earth-2s Harrison can develop a speed-dampening serum.
And with surprise on their side, the two of them believe the plan will work.
Everyone else isnt so sure.
Lights escape is a sign that their current plan may be a foolish one.
Iris brings her to S.T.A.R.
Labs, where Barry, in his Flash suit, asks for her help.
Linda eventually catches on to aiming and hitting only her targets.
No one thinks shes ready, but Barry plans to convince Linda to remain involved.
Barry brushes the latter idea off for now but takes to heart that he has to consider Lindas part.
Barry tells her he believes in her, though.
So he removes his mask and reveals his true identity to his former flame.
(I made out with the Flash, she exclaims in an episode-best line.)
With that show of faith, she agrees to don Dr.
Lights outfit and hold a fake duel with Barry out by the docks.
Grant Gustin channels Wentworth Millers scenery-chewing Captain Cold performance in his inflection before the fight finally commences.
A few hits and Barry takes a fake fall.
And so they wait, over an hour passing without a sign from Zoom.
They pack it in, Wells particularly displeased, while Barry comes to terms with his perhaps reckless behavior.
A death like the one Barry faced does leave a void, and its only magnified in his case.
He finds Patty, whos feeling particularly left on the sidelines at this point.
That happiness is short-lived, however, when Zoom actually comes into town.
He kidnaps Linda from outside the newspaper office, bringing her to the roof of S.T.A.R.
Zoom grabs Barrys bolt out of the air and hurls it back at Barry.
Barry leads his foe into the air, forcing the two to fight in freefall with an equal velocity.
He collapses, shocked by the hit, but still speeds away, leaving a bruised Barry behind.
While Barry recuperates in a coma, his vitals having stabilized, the tension at S.T.A.R.
remains at an all-time high.
He saw Harrisons daughter Jesse in a cage being held by Zoom.
For now, he believes he may have been wrong.
Earth-2s Oliver Queen is dead, while his father Robert is the hooded vigilante.
END ASIDE)
And it remains to be seen how much help Barry will end up being.
Earth-1 Harrison Wells wheelchair is still around, right?
