This theory is completely incorrect! You say that the Arbiter is still working for the Covenant? Did you play the last level of H2's campaign? Right at the start, quite a bit before you reach the humans, you are killing the remainder of the Covenant. Also, you do this a few levels back where your only allies are the Elites. The Elites are no longer part of the Covenant. And the Covenant are not in league with the Flood. Why bring this up? Because Cortana was (for the most part) taken by the Gravemind at the end of H2. At the largest speculation, she is now evil blah blah blah...it's in like five hundred threads by now.
