Hey, the season established a... second kind of sleeper agent with the chips (we already had Institute synths) - except unlike synths, these are effectively new people post-chippage, which means they can't really engage in any subterfuge, so I'm not sure what the point is, other than pacifying savages?
Honestly, Steph is the most interesting part of the season - being Canadian, her goals aren't going to align with The Enclave / Vault-Tec. That said, her storyline doesn't appear to make much sense either - she wants the E(nclave)-Boy _before_ Woody overhears the conversation with Betty (and Chet finds out she's Canadian), so she doesn't want the E-Boy to pacify the riot, which leaves, what, she wants to Phase 2 Vault 32 so she can chase after Hank? doesn't like being Overseer*? What's her motivations here?
*Also, why is Vault 32 saying "Death to Management"? Overseers are elected - we saw it happen in S1 for Vault 33. Even if you theorize the vaults are rigged to promote overthrowing the overseer, that completely goes against the designed breeding program of Vault 31. I'm unconvinced any of this actually holds together.
Lot of people being reminded of Westworld, which in S1 took an existing sci-fi property, used great plotting and flashbacks to tell a tight storyline... and then fell apart in later seasons as the writers rooms apparently devolved into "Anyone got any ideas for next season, because we sure didn't set up anything?"
