I did enjoy Rayner flinging the breen to the barrier.
But...he said it'll take them decades to get back suggesting they still have standard warp.
But...book mentions a run in with talaxian pirates and we've seen at least one other delta quadrant species in the alpha quadrant this season which to me suggests that faster warp is ubiquitous.
So surely the breen can get back sooner than Rayner suggested? They can't be that far behind even the talaxians in terms of warp can they?
Yeah... pretty much everyone still uses standard Warp (the Breen included).
But regardless, some things don't make a lot of sense to me.
It looks as if they can make runs throughout the Galaxy at normal Warp easily if its in the inner spiral section of the Milky Way, but if a vessel is far enough away, it will end up taking them decades to get to a certain location (it was said that Disco would take about 70 odd years to return home from Species 10-C location - which isn't too far away from the Galactic Barrier (the original 10-C planet was about 2.5 Ly's away from the barrier, and their new home was not too far away either - so I think Disco remained within 10 LY distance of the Galactic Barrier after breaching it - its the tens of thousands of Ly's on the inside of the galaxy, from the barrier back to Fed HQ or the location of the binary black hole system that matters).
This suggests that Warp speeds didn't fundamentally advance beyond the 24th century it seems. Or they did, but in very small increments that it was negligible.
Either way, Warp speed remains inconsistent on Disco as it did on other shows - though its possible they used TW corridors here and there to get around more easily to certain locations... its just that where Rayner flung the Breen Dreadnought there weren't any TW conduits of subspace corridors to lessen the trip.
