At first I thought she was Erza's twin sister like Yukino and her sister but Erza didn't know how she was and then I thought back to the beginning where they show that Erza was raised with Jellal so I think hat may be her mother idk but I think she might
At first I think it was her mother but maybe she was her future self. But let see what will happened
I cant wait to see what happens the guessing is the most nerve wracking part
I think it was erza twin sister. Like yukino and angel they are long lost sister who meet in a long time. So I think it was erza twin.... I hope so
