The relationship between chief and cortana was great, truely amazing. A story worth telling, but after cortana saved chief at the end I nearly cried. And I’ve seen a lot of clips about halo 5 and something is a bit off about cortana. To be honest I think cortana ‘died’ in halo 4, it like a hollow shell or ghost has taken the place of her. I feel sad. I wish cortana came back.
