Quick note on this: This is now the third time something along these lines has been mentioned - the Visual Guide stating that the UNSC don't know whether the Ur-Didact is dead (don't remember the exact quote), the science team in Primordium questioning Chakas about the Ur-Didact and his history with humanity (as well as Chakas saying: "We have faced the Didact before, and now, and perhaps ever after. This is combat eternal, enmity unslaked."), and now this.
