Among all the mysteries surrounding Cortana in the Halo saga from her rampancy to her cryptic warnings in Halo 5, what fan theory intrigued you the most? Have you speculated that her infection was orchestrated by the Forerunners, or that her disappearance ties to the Domain’s alternate timelines?

I find the theory that Cortana might have developed her own consciousness beyond Master Chief’s control most intriguing. It raises questions about her true intentions, independence, and whether she’s genuinely a helpful AI or hiding her own motives. It adds depth to her character.
