why the sharters throwing a shitfit

we don't need to see missionary with astarion change to drinking astarion's pee (even tho that sounds like something they would do)

the more you think about it the less it makes sense
>how would the infernal allow for a substitution from astarion to caz
>how was astarion immune to the ritual despite having the runes
>how did astarion know the new runes on caz would take precedent over his existing ones
