Oh man, when I saw Frakes name I had high hopes for this. Not going to write too much about the episode but I have no clue how they are giving this series a satisfying finale in that very last episode after this!
One thing though, what the hell was going on with Discovery when they tried to find that clue within the two black holes. They go in, get out of the two black holes, see the container and are like, let's talk this over how to get this thing. Then the Breen swoop in and tractor that bucket into their cargo hold within 5 seconds! What gives? That was just needless incompetence. The Discovery crew is seriously not that stupid.
Why not having the Breen swoop in as Disocvery is attempting to escape. Then while Discovery is heading out the Breen grab the clue. Could have made up some technobabble about how some radiation from the black holes obscures Discovery from the Breen or whatever.
Anything else but what was shown. Damn. How is this so hard?
