Pretty great episode!
So that reveal on Bernard was what I anticipated (somewhat) and Dolores also implied that she was into "a bit of a timeslip" - so I think the multiple time loops is definitely what's going on.
Also, I was watching with my friend Rio and when Ford had that little speech about repetition and variation she googled it and she came up with this classic philosophical book, Difference and Repetition by Gilles Deleuze: [link]
Check out a couple of key quotes especially in relation to the lives of the hosts, but it's much concerned with memory, patterns, individuation of self...
***********
Passive synthesis is exemplified by habit. Habit incarnates the past (and gestures to the future) in the present by transforming the weight of experience into an urgency. Habit creates a multitude of "larval selves," each of which functions like a small ego with desires and satisfactions. In Freudian discourse, this is the domain of bound excitations associated with the pleasure principle.
2. Active synthesis[edit]
The second level of time is organized by the active force of memory, which introduces discontinuity into the passage of time by sustaining relationships between more distant events. A discussion of destiny makes clear how memory transforms time and enacts a more profound form of repetition:
Destiny never consists in step-by-step deterministic relations between presents which succeed one another according to the order of a represented time. Rather, it implies between successive presents non-localisable connections, actions at a distance, systems of replay, resonance and echoes, objective chances, signs, signals, and roles which transcend spatial locations and temporal successions. (83)
Relative to the passive synthesis of habit, memory is virtual and vertical. It deals with events in their depth and structure rather than in their contiguity in time. Where passive syntheses created a field of 'me's,' active synthesis is performed by 'I.' In the Freudian register, this synthesis describes the displaced energy of Eros, which becomes a searching and problematizing force rather than a simple stimulus to gratification.
