I still think the key moment from this episode is of course when Data is being beamed back and his phaser is in discharge. Did Data lie? Was it simply a natural deduction of his program to attempt to kill Fajo, and it was simply good timing that he didn't end up doing so? To me this is one of the most intriguing questions from TNG and it was a shame it wasn't somehow followed up later.
I remember that part of the episode even though I haven't seen it since it was on originally. I thought it was cool that Data "decided" to get rid of him but then seemed to lie about it. I wish they built on that.
