In the last cutsene when Noble Six falls to the ground you clearly see him/her fighting off the remaining Elites but the Red one is very special...Hes the one that killed Kat, so wouldnt you guys think that he would kill the rest of his team off, My answer...NO. Because right after he comes back to finish Noble Six off, another Elite is shown on the Helmet camera. All you see is his foot and a sword poping out from the LEFT side. Take note only certain types of Elites are allowed to wield a Energy Sword on their left. Like the Arbiters!!! Im not trying to say that the Arbiter from Halo 2 and 3 was there to save the day, anyway it was during the war between the Humans and Covenant so he was still bad. But my point is why would the creators add an extra scene to end it off...I mean if Noble Six was going to die then just kill him/her already. Also we didnt finish seeing the Red Elite going all the way down to stab Noble Six. Maybe the Unkown Arbiter told The Red Elite to stop so they would just capture Noble Six to get information about Earth or Oni Secrets Out of him. Fortunately this is just a theory and hopefully a good one too. Leave comments of what do you think, or any other theories too.Thanks for your time.
