Someone else thinks that after seeing Laura in his hotel room Gordon seems more sensitive, with an improved perception?
After seeing her he saw the vortex in the sky, had the dream with Monica and in last episode he just felt Diane was outside the door.
He also spent some time listening to the FBI equipment beeping which I think links to some kind of communication with Dale.
I was quite....impressed?.....that he knew Diane was on her way.
But then Gordon has always been a little "spooky."
The beeping of the machines segway into the exact beeping of Coop's heart monitor in the very next scene. I think Gordon is very in tune with a lot...
I think he machines are monitoring Diane and her communications.
They knew she was coming after sending the incomplete co-or that she got from Albert.
