Scream in the woods while she was being saved by good Coop exactly the same as scream from Texas Laura at the end.

Whoosh sounds during the Sarah stabbing picture scene (which was a small time loop) same as whoosh sounds in woods as Laura disappears and scream is heard.

Motel Mr C(?) and Diane go into is a hotel when C leaves.  Because it expanded over the years? Also, the car the night before was old fashioned and also the same I believe Mr C crashed early in the season. (check that, i'm too lazy)

Why would good Coop want to lead Laura to Sarah when Sarah is clearly a very evil being who wants to harm Laura.  Even if Laura is "the one" she hardly has the faculties to do battle royale with the face eater.  And it sure seemed like good Coop had been briefed fully on the events of the future by Major at some point.  So he should know Sarah is not very groovy.

Last evidence of good Coop existing is when he leads Laura in the woods and then seems to go back to the lodge briefly after she vanishes.  Who's to say the Coop we see exit the lodge is the Coop that went in? Or that those two events are actually linear or connected? We also see Mr C burning in the chair but he doesnt go the same way the Tulpas did, not exactly.

I'm thinking maybe everything after Coop leaves the lodge to meet Diane is all bad Coop.  Also that Laura is the antithesis to Sarah, and they are both in a perpetual cycle of annihilation. Bob was created by the entity that infected the young Sarah Palmer, and somehow Coop was manifested by Laura.  The horse represents death, then rebirth to try for a better life, then death rebirth etc.  Laura repeatedly screams like she is being killed. She is often sucked away while screaming, only to come back, whisper again, scream suck away etc.  Sarah stuck in time loop. Karma is obviously a theme given Dougie's super luck (good Coop's Karma).  This seems to be all about atonement for the massive sins of humanity (A-bomb being only an example).  And regardless of the whisking about through time, a better job must be done in order to finally save Laura and Sarah et al from the endless cycle of suffering and death and happiness and life.

Just ask Dr Amp, get a golden shovel and shovel your shit, in order to save Laura.
