That's one of the most underrated aspects of the death scene to me; you see how the other characters react to it. It makes the scene more powerful in my opinion, seeing your party go through their own emotions after seeing their friend die. And the fact that Square took the time to give each character a unique reaction gives the scene a kind of replay value, seeing which characters react in what way. I especially like that there's no dialogue, and even the limited animations are able to communicate so much emotion, like Tifa running off with a hand covering her face or Cait Sith slinking off in shame after realizing the comedy act isn't working.
