Earth-38 was full of aliens and Earth-1 is not (apparently)
And since almost 3 billion peoples have come to Earth-1 to take refuge.. among them will be some aliens too, so how are the people of earth-1 gonna react?
In fact in general, people aren't even aware of the multiverse, they don't know their multiple doppelganger exist.
I am looking forward to how they set it all up.
ALSO LOOKING FORWARD TO OLIVER SOMEHOW COMING BACK, NOT NECESSARILY RESURRECTED.. BECAUSE AS MUCH AS IT WAS SADDENING IT WASN'T A 'PROPER' GOODBYE THAT HE REALLY DESERVED.
