It came to my attention that there was dispute over the identities of Irene and Dan, the old couple that re-emerge throughout the film, as the word 'grandparent' is not used once in the film. Having now read the original screenplay, I'm almost certain that these two are indeed her grandparents, as confirmed by Coco:
COCO
"I guess it was your grandfather, was
it ... he called me to check in, said you
were on your way and for you to call when
you get in. Nice man... farmer I hear.
BETTY
Yes, he is. He raises corn.
COCO
Damn lot of corn raised in Hollywood
these days too."
The phonecall exchange Betty has with her Aunt in the film was also originally a conversation with her grandfather. (The fact that their conversation is jovial does nothing to disprove the abuse theory, as although the Diane character exists in the pilot, there is no indication that Lynch has realised the Diane we know as of yet.)
The annoying part (
) is that the old couple are still referred to as 'Irene' and 'The Old Gentleman'. Can anyone help me with this? Here is the screenplay: http://www.lynchnet.com/mdrive/mdscript.html
