To fill in about some Greys, we have taken enough people to between lives recall that it is becoming commonplace to find a pod of Greys ruled over by a Reptilian. The purpose of their programming and implanting humans seems to be related to having a labour force and to bring the planet up to an ecoenviro that is suitable for Greys.
Here is the thread of my notes on two separate people's sessions. Now there has also been a third person independently confirming what I and another person saw that occurred in our between lives times.
