First this is pure speculation but it has been hinted that the Mitchell sisters especially Ronnie i think has a secret that could tear the Mitchell family apart.
They is also rumours of Ronnie and Roxy's dad Archie Mitchell being cast.
So what is the secret?
I'm thinking maybe Eric Mitchell (Peggy's husband) is one of the girls biological father or vice versa Peggy had an affair with Archie and he his Sam's father
