The C's have already answered a question in a session not long ago. There are 3 million 'undergrounders' Nation of the 3rd Eye already here. Especially in the positions of power and control.
As to how they create and gt these 'hybrids' down here, the best book on this subject is The Threat.
Alll of us would already have met some or are aware of them in power positions.
It was also posited that Zuckerberg of FB could be one of the undergrounders, and the C's did not deny this.
All abductions are about this experimenting and impregnating into women here. Who also have 'minders' who ensure the 'safety' of the embryo, and also the continual abduction of that person, and persons in that woman's family.
I was discussing with the Forum here :
I wonder if these "workers" are becoming the militarized police? I just have found it so odd the behavior of the police in recent years. It just amazes me the amount of brutal police they can assemble in no time, like after the Boston bombing, or at protests. It's funny, I've often thought of...

They said 3 vehicles with 12 million Nephilim each, that is 36 million, plus they said if I remember right 2 million grays, 300 000 lizards and about 30000 or 60000 oranges, Aryan sts specie, already here(many variables of Grays, 3 variables of lizards and Aryans, not mentioning reinforcements coming and those workers in underground bases and other underground Aryan civilizations which are eagerly awaiting to go to surface and C s said they are under 4D STS control and they maybe went underground to escape cataclysms, maybe descendants of Atlantian people). It is going to be slaughter if some of us live long enough to see it.
Probably you can expect full blown invasion after comets but they will appear prior to that I think, probably Aryan species because of similarities and little bit of peace propaganda and high tech marvels will do the trick for people that when the chaos through comets strikes they will go with them to underground bases or ships. Some abductees are programed to direct people in right direction when the time comes but everything is open so do not take my word for some scenarios.
