Don't know if this is relevant here but I just came across this in the latest Community Update.
"Completing the trinity of villains in Baldur’s Gate 3 is Orin, a practitioner in the art of inflicting pain and a grandmaster of murder. Orin has killed for many years, but has yet to be caught, thanks in part to her shapeshifting abilities, which enable her to take the form of anyone – perhaps even someone in your camp.
She hides her cravings to commit murder beneath these numerous masks, disguising her intentions and herself to lure unsuspecting victims. It’s during the act of murder that she is her truest self. At that moment she is murder."
Maybe she shape-shifted to a tadpole.
Or maybe not.
