I always wondered what the point was of the COTEOF scenes involving McCoy's phaser (ie, McCoy taking it from Kyle, the bum stealing it and vaporizing himself). These scenes didn't seem to be crucial to (or even necessary for) the plot. I'm not fully versed in the original Ellison version of the story; perhaps these were left over from scenes in the original story?
Also, did the bum shoot himself or set the phaser on overload? His manipulation of the phaser suggests the former, but the sound effect suggests the latter. If it WAS an overload, it seemed awfully simple to initiate! Also, aren't phasers on overload shown in other episodes to explode ("Conscience of the King," "That Which Survives") rather than dematerialize?
