What I see: A man of high rank who looks crazy, but is enjoying his reflection in the mirror. However, the reflection does not show the top of that dagger the dismembering hand is gripping, just as it does not show the candle he is gripping in a perfectly lit room.
What I feel: If the mirror on the wall is NOT showing you something, you are in trouble. You just don't know it yet.

Milady Maleficent's mirror obliged by not showing him the dagger in the hand that would carve a line across his throat.
Milady later smiled triumphantly upon finding Lord Looney dead, her pretense at defeat and retreat having worked.
