As we all know, Cortana got the ending she deserved in Halo 4, the penultimate moments showing her giving everything to protect Master Chief from the Didact and ensure John survived and the ultimate moments showing John-117 mourning Cortana in his own stoic way aboard UNSC Infinity. Now the question looms on the horizon. Was Cortana's death simply catharsis for the ending of the Bungie Halo Trilogy? A closing of the wounds caused by the transfer between Halo 3 and Halo 4? Or will Master Chief's new mission be to restore Cortana using her AI Data Chip, perhaps to imprint a new Cortana using Dr. Halsey's conscious? Or perhaps Master Chief is searching for the Composer; the piece of Forerunner technology used to build digital life and organic life, to create a human Cortana from her AI Chip. It's clear there is a lot to explore in Halo 5: Guardians, and with details thin on the ground we cannot know for certain. However, 343 Industries Bonnie Ross has said Halo 5 will be "a deeply personal journey" and Chief will be searching for answers, "this is about his past and his future." It is almost impossible to say for certain, but hopefully this isn't the last we've seen of Jennifer Taylor's Cortana.
