I was thinking in season 2 when Catlin was looking for a cure for “Jay Garrick” (Hunter)
She said “Everyone has a doppelgänger”
Which she of course was mistaken.
Catlin on Earth 2 had a brother. But not on Earth 1.
Joe & Cecile has a baby on earth 1, but Joe died on E2 and Joe & Cecile as far as we know weren’t together. So that means Jenna doesn’t have an Earth 2 doppelgänger.
Mia Queen Because her dad ‘Oliver’ died years before he would’ve had her
Anyone else we know of who doesn’t have an Earth 2 Doppelgänger?
