<p>as you all know, Dumbledore intended to hire Alastor Moody to be the defense against the dark arts teacher in harry's 4th year. Moody agreed, but was overpowered by Barty Crouch Jr before he could actually start teaching. </p><p>
</p><p>so my question is, after the events of book 4, why did the real Moody not take up the position? he had already agreed to become the new teacher for the class, and dumbledore wouldn't have to accept someone from the ministry to take over the position.</p>
