Just watched the movie [b]Oblivion[/b] again and thought that the [b][i]Scavengers[/i][/b] look a lot like [b][i]Fallen[/i][/b] and the [b][i]Drones[/i][/b] look a lot like the [b][i]Servitors[/i][/b]. At the final scene We get to see the TET from the inside and looks similar to [b][i]Vex[/i][/b] constructs.
