You know, I was kinda predicting that something like this would happen. You don't just introduce a subplot like 'personalized holographic recordings from beyond the grave' and then not use it - it's just too juicy. (The question is, was it introduced specifically to set up the 'Jason goes whackers' storyline, or did the writer simply go 'oooh, THERE'S a good way to explain it!') And did anyone else think it was somewhat uncouth of Dick to dig out the recording like that? (I was going to say 'dickish', but that brings up some logical problems.) I mean, those things are PRIVATE, man. Sure, they needed to find out a way to stop him, but since when has the 'bring out the thing that turned a guy crazy and say 'this is what turned you crazy'' plot device ever actually STOPPED said guy from being crazy?
'You know, Artichoke Man, I'll bet you dollars to doughnuts that it was this rotten artichoke heart (which I happen to have a facsimile copy of right here) that drove you insane all those years ago.'
'Gosh, Mr. Hero, you may have a point. My, my, now that I have confronted that, I feel my mania ebbing away. Would you mind knocking me out and taking me to prison, just in case it comes back?'
'Glad to oblige.' WHOCK!
It don't work like that. All that EVER happens is that the crazy guy gets even crazier, and well you ought to know it by now, Dick. Respect the man's privacy, for cryin' out loud - how would YOU like it if HE brought out your Bat-recording?
