The LAPD office who orders Rafi and Seven out of the stolen police car is a rookie as their shirt done up to the collar but is missing a tie. Non-rookies show a white undershirt.
Raffi and Seven take a bus to get to the LAPD station. In Assimilation (2022), Raffi robs the mugger and is shown removing a wad of bills from his wallet and stuffing them in her pocket as Seven shows up.
As seen in Time's Arrow (1992)/Time's Arrow, Part II (1992), Guinan appeared in 1893 as played by Whoopi Goldberg. It makes no sense for Guinan to appear 20 years younger a century later and then back to normal for TNG.
Depending on how the rules of time travel work, Guinan should have known who Picard was since their first meeting in 2024 was before Q changing the timeline. Thus, she should have recognized Picard from their time together in "Time's Arrow" set 131 years prior.
