The subjugated elder brain is an interesting concept.
What if the illithids who captured the player character are trying to save the elder brain in question by making the player being their pawn to join the absolute and discover what's going on and where it is located? It would explain why the tadpole is dormant.
I doubt this, the Flayer onboard the Nautiloid thinks you are his thrall, after all.
But he's the one who put the tadpole inside your head. So are you suggesting he doesn't know it's a special tadpole which has a different purpose than the ones they usually use?
