Did anyone else notice the marks on both Locke's and Chief's armor in the live action trailers? It looked like a mark the flood leave. If a gravemind was messing with their realities, it could also explain the dual perspective. If the gravemind targeted both Locke and Chief, it would create an alliance between them, similar to the one in halo 2 between Chief and the Arbiter. It would make sense that 343 is trying to do what bungie did so well. Well, that's it really. Any comments? Agreement? Disagreement? I wanna hear what you guys think.
