Knowing Jesse is in Zooms hands, Harry wants to head home, save her, and defeat Zoom.
Even Wells himself doesnt think he should stick around, despite Caitlins attempts to convince him otherwise.
That plan failed, and so he needs a new one, which he thinks going home will facilitate.
Hes set on going until Caitlin mentions the breaches between their worlds.
Close all of the breaches except the one in S.T.A.R.
Labs, then set a trap for Zoom to speed right into.
Those plans are put on hold, though, when Caitlin is kidnapped.
He uses mind control to lure her out of S.T.A.R.
The rest of the team wastes little time in realizing Grodds threat level.
Labs security footage shows Grodd with Caitlin outside.)
Harrison shows up in S.T.A.R.
Theres a method to his momentary lapse in judgment, though.
Barry agrees to the plan but admits he wont be of much help back at base.
So the gorilla throws his fake father across the room.
NEXT: Like father, like son
Despite the setback, Wells attempts to fool Grodd.
Its another case of fatherhood defining the characters before us.
Of course, Barry is still quite unsure of himself by this point.
Henry makes a welcome return to the show thanks to a call from Iris.
And with his return he wants to restore his son to the proud hero he knows him to be.
At a time in Henrys life when all seemed lost, Barry saved him.
He expected to spend his life in jail for a crime he didnt commit.
So hes here to return the favor to his son.
So Barry heads into combat.
Why do all of the breaches in Earth-1s Central City open all around Earth-2s globe?
She asks Grodd to trust her to bring him to safety, to give him peace.
The Grodd conundrum solved, team Flashs efforts are rewarded with a little family time.
Its a woman, specifically Kendra.
And it looks like there will be plenty of explaining to do in this relationship as well.
Good thing a crossover looms in the not-too-distant future, huh?
