Are the Librarian upgrades ever really explained (to either Cortana or the Chief)? Even if it's in the books/comics? I hope they explain that more -- including the extent of what Cortana was able to do in Halo 4 -- in Halo 5. That's the only real story issue I had with Halo 4.
Halo 4 ending spoilers, even though I'm pretty sure everyone already knows the story to that game:
I never understood how Cortana was able to really protect the Chief at the very end after the bomb goes off. How did she have that power since she's really just an AI?
