I do recall seeing the FMV at the end of Disc 1 and I'm like....what the crap? They're killing off the main character already? Now I don't have any huge information regarding him dying though I do remember something about this.

If you look closely in the video, where Squall was actually attacked did not go through his heart. Although he may of lost a lung or a kidney, a human can still survive from that attack...granted they would be lucky, but they could still survive.

As much as I love VIII, there have been loopholes in the game. Specially with Ultmecia, the fact that she just showed up in the game in the 3rd disc was just weird to me but ah well
