One chance out between two worlds
The Giant's scene: is it future or is it past? He is the older version of himself, and you could well put that on the aging of the actor, but it puts some pressure on the idea that he is there operating in the 40s or 50s or whatever. And whatever is going on with the Laura orb. She clearly wasn't born until the 70s. And then there is the Bob orb...
Weird temporality is at play.
"between two worlds" - I don't think we saw the origin of Bob, or the Woodsmen/Dugpas, but maybe a chance out of this liminal space or something like that.
(one chance of course ignores that if it took a nuke going off they would have had about 3000 chances)
