See you on the 9th green at 9
I agree but the only character I see as indispensable is Harold. As much as I love Root, Reese and Fusco the show would go on if they were killed off.
I meant kind of I could see Root dying protecting the machine. I could see Harold in a position where he and the machine both 'die' together. John finally finds love and moves on with his life. Fusco continues policing. I don't think you can have the show without Harold and Reese tbh. They're the originals.
