Timeline 1: Right after Season 1 ends
S2E1
- Bernard & Charlotte finding secret bunker
- Dolores & Teddy causing mayhem
- Maeve & crew looking for her daughter
- MIB (Man in Black) door adventure
S2E2
- Dolores on a mission to "wake" Teddy and recruit those to their cause
- Dolores (and team) and Maeve (and team) briefly meet up but go their separate ways/separate missions
- MIB continues on his adventure where Robert seems very much present (Great acting from Giancarlo Esposito, but not really needed plotwise)
Timeline 2: Two weeks later after Timeline 1
S2E1
- Bernard & "Rescue" team
S2E2
- [nada]
Timeline 3: The Past
S2E1
- Appeared in some of Bernard's flashes
S2E2
- Arnold and Dolores in the real world. Quick appearance from Ford
- Presentation put on for Logan Delos with Angela and other hosts - agrees to financing Westworld (I think this is the first time is last name is revealed.)
- Sometime after William's first visit, he visits Westworld with Logan's father and his father in law Jim Delos
- William and Dolores have a private chat. William appears to have come to his senses and has an awakening of his own.
- Dolores plays piano and talks to Logan in real world years later as it seems Jim Delos is retiring/sick, and William and wife have a daughter
So this episode added more to the past, a lot more, with little to no explanation about underlying motives, but there was a lot of exposition, almost too much. Dolores remembers everything so she was collecting data before William thought about the idea of collecting data, so who's really in charge, right?
Since we got so much Past, we didn't get any Future concerning Bernard, which I assume we won't visit again for a while. The Present continued the plot lines right after the finale of Season 1 and it was mostly setting up future events. Not sure how much of a rush they are in. Maybe Dolores knows how long it's going to take for the rescue team to show up.
