im not too well versed in shipping info but i think technicallly they could both? be considered a comship ( aka a complicated ship ) because of the circumstances, i.e. arle literally trying to assassinate furina before finding out she doesn't have the gnosis, furina being afraid of arle, then dottore literally experimenting on scara, and im also pretty sure dottore had things to do with scara becoming a harbinger and somewhat... basically.. cough.. looks side to side scared. grooming him into the fatui. of course theres nothing completely wrong with shipping these ships because technically they are legal and adults, its just a thing of morals basically.
