>>6172058Deep Winter lasted a long time for an AI too. Along with Loki and Mack. Juliana remained functional for an unusually long time as well.
>>6172129Halsey was really protective of her Spartans, even the 'dead' ones, who she hoped were revived one day. And the 'scans' to create smart AI are invasive and destroy brain tissue, so I doubt she'd go along with ONI doing that given she was against autopsies.
Stanforth (ONI Section Three head) is also a reasonable guy and supports her, so being in his sphere, she has enough protection and influence in ONI to let the Spartans keep some dignity. Parangosky I guess could overrule it, but she begrudgingly accepts Halsey's quirks (compassion for the IIs) when the Spartans almost immediately start proving their value.
>>6172138The funeral service with closed caskets was just symbolic for the Spartans as a form of closure. Halsey put them into cryostorage, hoping to revive them later. A similar thing happened to Linda during the fall of Reach - technically died, immediately put in cryo, later revived by Halsey.
