Well the Worms themselves don’t get any special mention. It’s also symbiotic, so whatever is done to the Worm affects her. It’s like an organ at this point. You need it to function. They haven’t been shown to exhibit any sentience or independence. What we do know is that Hive have been Taken with only their will being affected. So based on what we do know and the lack of mention otherwise, Taking her Worm won’t do her any good.
