I think it's actually just Tav. And by that I mean, ONLY Tav, and not PC Gale, for instance.
Everyone has their own special story thing going on, and Tav's revolves around the tadpole. Astarion about the people he bites, Gale's is about the books he eats, and Durge's about the Urges.


Fear my wrath, for it is great indeed.
