Priestess Gut can learn of the tadpole if you let her put a non elven/half elven party member to sleep. She is convinced it is a normal tadpole until you don't transform. She, and by extension, the Absolute, don't understand why you don't transform. But outside of mind probing, which she acknowledges, Priestess Gut seems unaware of any other powers.
You can also mind-probe her tadpole in an earlier part of the conversation. Her tadpole doesn't appear to be aware like the one the party member have, too busy being "high" on faith.
