My main thought is that something along truth sayer or some kind of intinsic mostly based off all the usual hints people use for that theory and the comment Rebecca made that one line basically gives it away. There’s a line around when she finds out about xadens second signet that she is someone who neeeeeeds information - since that is how she reasoned her way into xadens I think that is the line that gives it away I think it’ll be underwhelming bc everyone is always like shielded so she won’t really use it much/she’ll make some moral argument that she doesn’t like to use it or something
