There is a certainty and teleology in the show that I didn't see in the book In Nemesis Games you knew something was about to go down but didn't know what and from where or who was the ultimate mover. Contrast that to not only knowing that specifically marco is up to something but that it's an asteroid attack. It's easy to see it as a wink to book readers however it significantly alters the narrative I think. The inners aren't caught off-guard by some belters who weren't on their radar but they were foiled by a master terrorist because they didn't listen to the hawks and failed to provide the military industrial complex with what it needed.

I'll hold out a final judgement until we see how they introduce Laconia though.
