That could be true. I hadn't thought of that. We really don't hear anything at all from the scan Ghost tells us. And we've never heard another ghost talk before so we can't necessarily say we know all Ghosts sound the same. Which, could in fact, be that ghost trying to contact anyone to let us know it'll be there. It would be even more convincing if the dead ghost you found in that area in that alone, super small building near the ship was connected to a Hive grimoire card.
