- or finding out what was going on behind them...

Or breaking them down 

Yeah...Gordon's vision was the one part of this episode that has me intrigued.

Why he would have a vision of Laura when opening the door for Albert is a definite mystery.

Knock-knock

Who's there?

Laura

Laura who?

Laura who is the one

It looks like Gordon Cole replaced Cooper as a smart agent working on mysterious case(s), open to visions, dreams maybe? Time will tell, but remember this disturbing Lynch's Cole in one of the teasers?

That scene gave me a chill and the follow on with Tammy walking in the hallway, a lot to do with the sound and speed.

Also, not sure if it's always the case, but when Albert indicated in that scene for Gordon to up the volume on his hearing aid, I recall it sounding a lot more like it's 'changing frequencies' or turning through the AM/FM band of the radio.  Perhaps he uses the hearing aid to 'tune in' and listen to different frequencies.

Maybe he was tuned into an intuitive / frequency maybe and that inspired/helped him visualize his drawing and also triggered the Laura Palmer vision.  Maybe that explains why he can't understand some people (maybe when tuned into certain frequencies they don't make sense) (but I also really like how Albert called his BS one time, so not sure if that matters).  After that, I felt that the hearing aid serves more of a purpose than just an acting crutch and comic relief.

Such a intense, mysterious scene. But I'm trying to understand...

What was the significance of Cole's vision of Laura? Before I saw what Gordon saw, I was convinced he was going to get shot when he opened the door, because the ominous feeling. Then, when I saw that it was Laura crying, then fading over to Albert, I saw it as a "warning". As in "beware of this person". Like a memory/feeling of something terrible that has happened and that has lingered on.  But when I heard that the footage is of Laura from when she asks Donna if she is her best friend, then I thought of it more as a vision of someone who is desperate for help and that something awful is going to happen. 

Why is Tammy walking in slow motion and ominous music playing when she arrives in the hallway? 

I have to say while watching the scene Agent Preston looked to me as if she was unconfortable/not feeling well, but as the scene went on I stopped focusing on it and I just thought I was wrong on that, so did anybody else had that same feeling? Which is somehow weird if you also think about the scene earlier this season when it's Albert the one who's not feeling well.

I, too, have wondered about Agent Preston's walk, her facial expressions, and her body language throughout the series. In The Secret History we learn she's a meticulous researcher with a sharp, logical intellect. But all that seems juxtaposed with a demeanor that seems (dare I  say) either perpetually agitated and/or aroused. The way she touches Cole's shoulder while watching Albert and the forensic investigator appeared to be one of the few occasions she's actually appeared comfortable.

Loved the scene! i was like whaaaaaat? it was amazing, i thought something will happen when Cole opened the door for Tammy too. As for Tammy's style, walk, body language etc i found them awesome, it's all in her character which imo she plays extremely well!
