I love jen taylors voice. I love Cortanas epic lines. I don’t want her to die. 
It’ll make me so sad. Is there another option? I hate how cool people died in Halo 3… I don’t want anything morbid to happen to her
It’s likely Cortana will die by the end of the Reclaimer Trilogy, but I would love to keep her around for the majority of it. Her rampancy could make for some truly amazing plot points.
By the end of Halo 6, however, I believe both the Chief and possibly Cortana are going to parish.
