Hehe, love the last line. The tension and the responsibility of being a Prime Minister was built up very well; I liked the analogy of the soldier who gets his head blown off. So true. Great description of the Graveller's attack. I couldn't help but wonder why the guy was so anti-trainer though. I think I would have empathised more with him if he mentioned that the money from taxes could go to better causes like, I don't know, public housing. The way he was portrayed it sounded like he was just making trainers' lives difficult for the heck of it. Also, while the Nurse Joys being robots thing amused me, I thought the revelation was really too big to just be a side comment. It deserves a plot point of its own.
Great job, and I'm looking forward to more of your work.
