General chit chat, theories about who frankie is on eastenders?

[Ghosts2020]

Who do you think frankie is on eastenders? Just a light hearted chat. I think people may be right and she's micks long lost daughter, I would potentially go so far as saying her muam is also callums mum, but that's less likely?
What's your theories

Ooh interesting theories...! I just thought she was new/unrelated but fixed on Ollie because of her little brother. I'm a few episodes behind so maybe I have missed something
