I thought at the end of that installment she sacrificed herself by allowing herself to be burned at the stake, I think it was because she wanted the coven to move on and felt she was part of the past and the past had to die, forgive me it has been awhile since I saw that season. Regardless, I watched the third episode and I found it strange that they brought her character back from Coven without an explanation. They explained Queenie and Madison, however Myrtle’ s return was never explained. I am hoping they explain how she came back in subsequent episodes, otherwise it is going to be a gap in continuity.
