Ok so many good omens enjoyers have read The Doc making its rounds on here and I want to discuss the supposed hidden significance of the eccles cakes that op mentioned:
In short, I disagree that they meant anything important for season 3 because their symbolism was shown in its entirety through the context of the two scenes they are in.
The first we see of them is in the coffee shop when Aziraphale asks for something that calms people down, then in the next scene the cakes are shown, Crowley is leaving the bookshop in a barely suppressed rage. This leads the camera to focus in on a shot centering the eccles cakes, the established option to “calm down”, and Crowley’s glasses, basically the option to leave the bookshop in anger and go blow up outside.
I really think it’s as simple as that and that their significance is confined to these two scenes. I guess it’s a little peculiar that they vanished afterwards without being eaten, but what reason would Neil have to continue fitting them in without making them seem even more important than they are? Three is a pattern after all.
