User blog comment:Itamar20112/Arrow 8x01 - A good episode, but kinda breaks the Arrowverse/@comment-28398860-20191020222101

Why do you question whether Gypsy's alive? She's not from Earth-2; she's from Earth-19. Or, are you just touching on something they haven't explained yet (whether or not other Earth's have already been destroyed by antimatter aside from Earth-2)?
