Kandor

Ok, you might have caught this one "“ in the scout ship, the beautiful voice of Carla Gugino tells Lex that Zod was born in Kandor. And, as you might have known, Kandor is the one Kryptonian city that actually escaped the destruction of Krypton.

Well, this isn't the whole truth. Kandor did escape the destruction, but only because it was miniaturized and stolen by Brainiac himself.

So this could be yet another connection with the future of the DCEU. Who knows? Maybe Superman will defeat Brainiac in the Man of Steel sequel, and maybe he will establish a new Krypton on another planet. At any rate, this is one of the Easter Eggs that opens the possibility of having the Man of Steel exiting the DCEU for a while.
