Re: Cause and Effect (??)
If tyhe Enterprise had changed course, the Boseman would have emerge, hit nothing, and found themselves in the future.
The Boseman "looped" exactly as many times as the Enterprise did. When the Enterprise exploded and reset (how many hours?) the Boseman still being in the area of the explosion also reset the same time period.
This is pretty much exactly what I got out of this episode. The Bozeman was flying around in 2278 then flew into a temporal anomaly leading them 90 years into the future. They collided with the Enterprise and the resulting warp core explosion interacted with the temporal distortion in some way as to create a temporal loop of some arbitrary length, resetting both ships back a few hours in their respective timeframes. Bozeman wasn't trapped in the loop for 90 years, they were trapped for the same amount of subjective time as the Enterprise. They just happened to travel 90 years into the future during the loop.
That is what I always thought as well.
Also, remember that the Bozeman
crew (what little we saw of them) didn't show any signs of deja vu or uneasiness like the Ent-D crew did. Captain Bateson had absolutely no idea that there had ever been a time warp.
