consider this simpler example:
A, B and C are in a line. B is close to A, but C is far away from both.
A............B............................C
A turns on a lamp. It takes 5 s for the light to reach B, that's when B turns on a lamp as well.
A----------B.............................C
Now both light beams travel on and reach C 10 s later.
A----------B==============C
C sees both lamps turn on at the same time. Causality is gone! No, of course it isn't. Only from C's POV does it look that way. Every other POV can see that A was lit first and caused B to light up later.
well done, you’ve debunked physics forever

). It also gives more information about Book and about what happened to the Federation, Starfleet and the Burn. Yet, while it did that, it was largely spoiler free. It just gave a lot of good background on what was going on so when I started watching Season 3 I wasn't mystified by what they meant by the Burn, and other things. So I could get right into the season itself and know what they were talking about.
