I have a few questions. 1. Is it possible that Agent/Spartan Locke is a Spartan-II? 2. I'm not sure if it was Serin Osman or Margaret Parangosky (I believe Parangosky) who hated Dr. Halsey for those flash clones and all the lives lost for the Projects. But did she actually hate the Spartan-II's who fought in the Human-Covenant War? 3. Are there other Graveminds active in the Galaxy? 4. Where do the remaining Forerunners stand on Humanity claiming the Mantle? I believe the Didact stood trial at the end of Halo 4, so they must have some different viewpoints on that.
