Aw man, I love it when you get to a point where you start noticing really small things like that in movies. XD I SWEAR, when Cloud passes out in the church you can just make out two people running towards him. And it's totally Zack and Aerith. Of course.

I can see a suicide note being really cool if it was handled well (which you could totally do, of course X3). Beyond that, hmm... *thinking back to things that have happened in PW XD* Jumping off a bridge...? No, that was just used. Poison? Like, something that makes him seem dead? Hmm... Natural disasters? A bad earthquake that levels the building he's in, fire caused by lightning, avalanches, tsunamis... The missing angle wouldn't be too hard to do with a natural disaster-type thing. *shrug*
