Virus!?

[Kadaj]

I heard a while back from somewhere (I forget) that Sephiroth or Jenova had a Virus or something.

I never remember there being a virus. I know someone can get injected with Jenova Cells, but can you "catch" them?

[Yin&Yang]

Yes, Jenova carried a virus that turned the Ancestors into monsters and did more bad things...

[Ringlets]

I knew there was Star Scar, but didn't hear that. Sounds like another one of those hidden FFVII things that wasn't announced on the game. Or it was and i missed it
