Both Amaria and Titania get under my skin so much, but more so Titania honestly. At least Amaria we can just chalk up as being severely mentally ill. Titania, however, is just insufferable to everyone for no goddamn reason.
I give Saphira sort of a pass for being this same kind of stereotypical definitive badass character just because I understand her desperation and motivation after being exposed to Dr. Connal and his antics myself in the game, plus she isn't as insufferably aloof as Titania to begin with.
So Titania is basically Saphira but with none of the reasons for me to give a shit about her, which makes it all the more grating when she rags on the player no matter what they do. There is literally no pleasing this bitch. [Unless you give her ice cream, bitches love ice cream]
Pretty much everyone else is aight.
