These cant be the 2 PSP undercover dudes who were stationed at Sheetz? (holding Crooks hand) and recalled to the AGR complex or are they?.
Is black beard on the phone saying “is a go” To Nicols?

They certainly knew who Greg was before the shooting took place. Take a look here and the post that one references. What I believe is that Crooks deceived them at some point.
