Do you have any theories as to how Cortana even stumbled upon the Domain in the first place? Also, is it plausible to theorize that Cortana's corrupt sub-personalities that she "injected" into the Didact's ship are the ones that survived and made it to the Domain? Is it possible that, throughout Halo 5, we're not seeing the Cortana we've come to know and love, and instead we're interacting with some corrupt bi-product of the detached sub-personalities that were left behind on the Didact's ship and made it to the Domain?
