LoA I have a prediction In the ad were Locke talks to Chief its a Covenant Ship in the air and not Infinity like the one where Chief talks to Locke. My predictions is that when Chief talks to Locke its symbolizing he beat the UNSC. But when Locke talks to Chief its much deeper. I think that since there is a Covenant ship in the sky, that Chief was trying to find Halsey and get Cortana back. And you know Halsey is with Jewl man dama (probably got that wrong). I think that Chief some how reaches them and the UNSC catches them and they battle it out on this planet. Although these are just predictions
