As we all know after the whispers Sherry tries to revolt against rick where she is slammed against a table and 'dies'. Seeing as Sherry is MIA right now which character will take her place. I personally think it will still be a girl. Possibly Frankie, Tanya, or Regina
Regina seems to most likely out of the 3 as she is likely still Negan
Frankie seems a darker than Tanya personality wise, and seems like the type who would back stab given the chance as seen when she try to get Eugene to poison Negan.
Tanya is the wild card, she seems rather friendly and chill so i don't think she would do it but never know
