I had considered making this post the previous week when I heard a voice line where Failsafe mentioned individual Vex units seemed to be communicating with each other. But I completed this week's storyline, and the Nessus Vex are up to all sorts of strange behavior. Vex units breaking formation. A trio of Minotaurs staggering shields in combat like Titans and going straight for a Hunter's Ghost when they appeared to resurrect her. Seemingly building sandcastles. A Vex Hobgoblin excitedly waving at a Guardian (before a Titan blew it to smithereens). A Hobgoblin running when it spots a Guardian. A Vex Minotaur breaking its own radiolaria container to dump its contents into the radiolaria after being damaged. Another thing the entry made clear, which is true in gameplay but something I didn't notice before, was that only the Nessus Vex have the energy collars on them. The Precursor Vex you see throughout Echoes activities, on the other hand, lacked the collars. In fact, other Vex showed up and wiped out the collared ones, ripped out the radiolaria cores, and were going to go back through a portal with them. Before a Titan Thundercrashed them. So far, the Echo that crashlanded on Nessus seems to be causing drastic changes to the Vex residing there, and the rest of the Vex Collective seem to be trying to get things under control. Whether this new, potential individuality is due to the Echo fragment, or a product of our mysterious figure from the trailer harnessing the Echo to gain control of the Vex, we'll just have to wait and see.
