So with Halo 5 having the story it has, where and when does the conversation between Arbiter and Lock from Halo 2 happen? Is it on the way to the battle of Sunaion? Also are the events of Hunt the truth cannon? If so when did chief go and stop the attack on the diplomatic mission? Has he gone rouge multiple times? Where did the Brutes in Halo 3 Odst come from? They must have been in another area of the city while Chief was there?
