Sorry...yeah I forgot about Gast thinking Jenova was a Cetra, so he wouldn't have known all that.
I dont think it would have made much of a difference if he'd known he had a human mother....I just got to thinking because of his "was I made like this" line, referring to the guys in the tanks. It made out that he was bothered about that....but obviously he didnt really give a shit
Makes me wonder though, Ifalna told Gast all about how Jenova wasn't an ancient and was in fact a
very bad thing. But Gast was all like, "yeah? thats interesting babe. Now lets get bizzay!" *
I suppose he should have done something, knowing that a very dangerous creature was in the hands of Hojo, who was batshit crazy. Though its not made clear in the game, Im assuming Ifalna told Gast all that stuff after Sephiroth was born, but still, they should have incinerated Jenova or something.
Phew...I forgot how bloody complicated this damn game was. I really should stick to things I can follow, like Mario or Katamari!
*This didn't happen.
