It was a set-up, basically. Richard's plan was to go to some businessmen who had New Rocket ties, pretending to "expose" them (since Richard's actual, real job is in finance and investment, he can do this on an official level), then have Adrian pretend to be a New Rocket member whose job was to silence everyone who knew the New Rocket cover had been broken and cover up the evidence (while also implying that Adrian "infiltrated" Richard's company somehow). As Richard's narration notes, his plan will presumably result in all kinds of investigations, arrests, etc for the New Rockets while keeping Richard's Team Rocket involvement hidden. Richard intentionally had Adrian shoot him non-fatally as well as killing one of Richard's assistants (who wasn't a Team Rocket member, just an employee of Richard's company) to make the act more convincing, while having the New Rocket businessmen killed because, well, Richard and Adrian are Team Rocket members. They don't play nice. That scene's primary purpose will become apparent next chapter, but its secondary purpose is also to show what the face of the Team Rocket/New Rocket gang war is really like—violence between the two has been described secondhand several times before, but this is the reader's first time seeing the actual ruthlessness of it. I might not have made that as clear as I should have in the story itself, since obviously as the writer I know the full implications of everything, but that can mean trouble if I'm a bit too subtle, unclear, or vague on a point. Sorry for the confusion. Edit: I also realized on rereading that section that it's actually spelled Ninetales. How that "Ninetails" typo survived my proofreading process, I have no idea.
