Can we talk about how Ford, a character who canonically suffers from insomnia and is know for his sleeping troubles, falls asleep in the same room as Dipper in a relatively short amount of time?
I mean… look at him, he isn’t even tossing and turning like how we see once Dipper starts watching Ford’s memories.
Look at him, look at how much he must TRUST Dipper in order to just… fall asleep like that?
I think this may be part of the reason he gets angry at Dipper for placing that machine on his head (that and Dipper was fumbling around with the Rift). He felt it was a breech of trust, like Dipper had gone behind his back. Dipper was so scared because Ford himself was hiding his true motivations from him, so there were many unanswered questions that Dipper could only speculate on. Ford realized withholding information from Dipper caused him to become so suspicious and paranoid of him, which was why he decided to tell him about his past with Bill… sort of a show of solidarity and placing full trust in the kid. When he says “no more secrets between us” it was him realizing that holding onto secrets not only hurt him but also Dipper. Now if he only realized this for Stan and Mabel… although I think it was partly because he thought “they couldn’t handle it” whereas Dipper can handle it better due to his interest in the supernatural.
