I almost ignored every content of the post after seeing the word "(including Hassan)".
Anyway, so Nulls are heroic beings or reincarnated humans who had a big influence in the history thus getting a second life with or without their memory of the past. Though it was really strange to see those Nulls acting humane, having cities and communities. It may actually mean that those soldiers with Reeva are classified as heroic and now living the life they didn't get.
Zero is playing the major role! And Hassan... Thank you for reminding me that Hassan will be in the Roster. I almost forgot about him.
I wonder what will be the reaction of "Happiness Mc's Mirall" about his Father's death but I guess I'll have to wait for that. Maybe.
