I just had a thought about the title. If Kasumi's name is suppose to mean
hazy, misty, foggy and mirror seen as just devices to show various 
reflections of objects, then this title can refer to either Kasumi's change
in a subtle way or foreshadow the illusion or magic of what happens (i.e.,
it was done with smoke and mirrors, she is dead, she is not dead) or I am
reading way to much into this. Or it could just be referring to the Nanban
mirror and the smoke that follows destruction and death. I wonder if they 
are ticked off about that. (The Sandman fans should get that one.)
