So i was thinking about acotar specifically, and about why amarantha was obsessing over Tamlin and I had a hypothesis that she and him were mates, but bc he has a literal heart of stone he can't actually feel love or notice the mate bond. I think he just latched onto feyre bc it was a mix of: having a trophy concubine, having proof that he destroyed amarantha, a sense of guilt over having her killed, and that he was trying to fall in love with her to break the curse, but had no idea what to do, so instead of dumping her, he stayed with her to keep up appearances with the courts. But this would explain why amarantha went so berserk over having tamlin, bc she was feeling the mate bond, and just overly expressed her "notice me senpai" feelings. What do y'all think?
