Now we all know that the Artificial Intelligence that we know as Cortana is expiring, due to her service expiry date. In the E3 footage/video we see her turn rampant, or what appears her going insane. She quoted "I will not let you leave this planet." to John towards the end of the video which was pretty scary, her face went all eerie and such and it was quite an intense and scary moment, especially when you're in the dark.
Now, we all know why she's expiring but what do you think will happen between John and Cortana, the message she sends hurtling towards John was threatening and had a serious impact on him, clearly. So, what do you think will happen? Do you think something will be resolved or will he do something to her, after all, she is past her sell by date.
Post all of your thoughts and reasons below, I'm sure everyone is interested in hearing/reading what you have to say.
