the machine... >SPOILER<

I think at first the chief was human and cortana was machine but as the wars went on they switched
seems ironic hes human yet he acts like a machine and she is machine and acts human

BUT I have a few questions:

  1. why did cortana stay behind she could have been saved ?

  2. is the Didact dead or is he going to do a 343i thing like at end of halo CE ?

  3. at the end after the didact fell did Cortana turn physical and touch the chief ? if so how ?

  4. was there a legendary ending ? how is there going to be H5 if didacts dead ?

  5. what happened to that one elite who order to keep the humans away from the planet who hated humanity ?

the first part of this was to be a discussion anyone ?
