They're called the Flood, not Graveminds.
yes but the flood relized how much information he had and instantly got to work on making him a gravemind... If you look into it, it states he's a pregravemind, the weak undeveloped form of a gravemind, but still a gravemind.
And the Chief destroyed the brain, which is what they needed, so he didn't even get to be a Gravemind.
I know, but he was still a gravemind.... granted very temporarily... but still... sorry if its a big deal i'll change it
Remember this, he never got to be a Gravemind, but he was a Flood, even if he was close to useless at the time.
yes but PRE-GRAVEMIND is still gravemind, just underdeveloped..... seriously though... I can change it!
