I just played through Final Fantasy IV (FF2 on the SNES) yet again, and I think that Sephiroth should've just sent Yang to jump in front of the Sister Ray's cannon when it was fired toward the North Crater. I mean, Yang can handle that sort of thing, as is proven historically. And he'll actually be back in good health, fairly quick.

It's a shame that Sephiroth didn't think of this. I mean, seriously, even if you aren't upset about what happens to Sephiroth, you've gotta feel bad for Diamond Weapon.
