Ok guys this my theory on the vex and have been thinking about it for a while now. So what if the Awoken control the vex? I mean think about it ya know. In the Archon priest strike the queen needs the priest dead alive or whatever. And also if I remember correctly the cave to start the mission is normally filled with Fallen but you enter it's filled with vex AND Fallen. Even your ghosts says why are the vex here. Also think about how the vex show up just randomly UNTIL the Archon priest was let out. So that's my theory. What do y'all think?
