A member in the "Cortana's screams" thread has stated that a symbol appears when Cortana speaks about the shield and sword.
Indeed it does. Pause it at 55 seconds to see that it is a blue ring.
That's not all, though.
Look at it this way: "I am your shield, I am your sword." *A ring appears*
Get it? She (or Gravemind) could be implying that harnessing a Halo could be used for defense and a devastating attack.
If it is Gravemind speaking, then he could very well be saying that he is going to use Delta Halo as some sort of assisting weapon, and he is using Cortana as a means of communication.
Sorry that I created a separate thread for this; I haven't seen this theory anywhere else, and the other Cortana threads have nothing to do with this theory.
