Why did the Borg go after the Romulans and Federation outposts along the Neutral Zone and just stop there? But when encountering the Enterprise-D in the Delta Quadrant the Borg pursued them all the way back to federation space after being rescued by Q. It always did seem disconnected from the Borg plot. It turns out it was. I read the Borg were supposed to have been introduced after episode "The Neutral Zone" as a 3 part trilogy of episodes but a writer's strike prevented it. So why did the Borg stop further assimilation after the destruction of the outposts originally?
