Okay it's very clear that sharp tongue knows about nothing being cursed but when did she find out and how I like to believe that either before or after her birth is when she met cansu and I think it is in a dream sequence and she told sharp tongue nothing is The Reincarnation of kyoga and that she has this curse that causes her light and karabi to be reborn in each life and that they were under their protection and it's possible that she also gave sharp tongue the ability to see things and to know things that others do not cuz I think that it's possible that cansu had a conversation with sharp tongue possibly on the day before she was born and after her and her brothers were born Cansu told her that one of her grand Sons was also under the curse and the protection of the goddesses which is fire but as for me I like to believe that it was sometime after nothing's birth that those two meet but I'm not really sure I also like to believe that if possible that cansu told sharp tongue when she got sick that nothing had to leave the step to go find the shifting place and to go on to the stretch possibly because it was more safer there it's possible that nothing is grandmother thought that she was the only one protecting her which I believe her mother was secretly protecting her without anyone knowing and that cansu knew said she would meet nothing on the stretch and possibly feather to but then again this is just a theory that I have and I'm sticking to this Theory at least for now no matter what but what do you all think do you agree with my theory or do you have another theory in mind on Sharp tongue and her connection to the goddesses
