I think the tapole thing should be at 100% only a main character thing tbh. Strange choice to give it to everyone. Now every origin character has it's own backstory in the game + the tadpole and we are just the average Tav with a tadpole. And shadowheart hates us. Pyfekt.
If it would be so, Lae'zel would just kill your Tav on sight, Astarion wouldn't be even able to walk with you in the daylight, Shadowheart, Wyll and Gale would go away telling you "your problems aren't mine". It's part of their backstory that they won't be there and won't be your allies if not the tadpole.
