The part I'm most confused about with the ending is why -
Does making Gale go full ISIS against the Elder Brain in Act 2 cause all the people infected with tadpoles to turn into mindflayers, but if you do it in Act 3 it doesn't? And like shouldn't destroying the Elder Brain do that regardless of how you destroy it do that also? What changes between Act 2 and 3 that causes destroying the Elder Brain to not turn people into mindflayers? I'm confused.
