Also note that when you win the last battle, you command the netherbrain to destroy all tadpoles first and then itself. That also indicates that the worms will outlive the Netherbrain and turn their victims when it is gone.
I didn't remember this bit, but you're right. The question is, does this only affect any tadpoles on the loose or also those which have already merged with a host organism.
Well, given their insight into how Gale explodinating the Brain instantly transforms all infected (That aren't also caught in the blast), would suggest that it would affect the tadpoles that have merged.
It does make me wonder about some things...
Firstly: The Astral Tadpole. This seems to be an even more unique tadpole and you can apparently pass it around your group, meaning it's doing its thing and then leaving your brain. What's its deal?
Secondly: I wonder how this removal of tadpoles would end up affecting people. Seemingly the powers disappear (Though what of the Astral Tadpole that doesn't stay in your brain?) so I'm expecting either heavy brain damage or neuroplasticity.
Thirdly: Imagine being a person who stuffed their brain with tadpoles during BG3 and then had them all destroyed. Maybe you were lucky and neuroplasticity made you continue to function. What happens if you get infected by a new tadpole after that? Would it look at your swiss cheese brain and be like "Nah fam, I'm out" or would it be able to figure out your brains adaptations and know where all the new areas are located? (I suppose this also goes with the question about how tadpoles interact with different races, as surely different races have different brain configurations? Or are we dealing with crappy writing where every sentient race has a brain that is identical to human brains?)
