The Greys, and most extraterrestrials for that matter, communicate with humans exclusively through a form of telepathy, which we called suggestive telepathy because to us it seemed that the Greys communicated in a such a way that they were trying to lead a conversation to a particular end. In other words, they always had an agenda, and we were never certain if we were a pawn of their agenda or we arrived at conclusions that were indeed our own.

I think that’s why Fifteen didn’t trust the Greys. He felt they used communication to manipulate outcomes to their own best interest in favor of shared interests. And because of this lack of trust, Fifteen refused to form any alliance or TTP that was comprehensive or integral to our operations at either the ACIO or the Labyrinth Group.
