In the jump to the 31st century, the crew lost everything. History, family, roots, home. There was a feeling in fandom that they magnitude of this loss was not being reflected enough.
I think what we're seeing since then is the course correction...fallout from such changes, which in most cases, after such huge implications in every season, are unprecedented in their finality (no reset buttons, or episodic tv amnesia) in the franchise.
Without spoiling the rest of the season much, keep in mind that the statement of the season is about loneliness and communication, and how we were failing at this in 2021, and still are. The Burn is a metaphor for things that do this to us: politics, Covid, racism, etc.
