This interview Michael Cole conducts with Charlotte and Ric Flair seems to be entirely about planting seeds for an eventual break up. When Cole asks Charlotte if she can defeat Natalya at Extreme Rules in a Submission match without her father there, she pretends she doesn't understand the question and moves on. When Cole asks the same of Ric, he responds as such:
"Nothing is guaranteed. ... I said there are no guarantees but... I think she'll win, yes."
This leads to Charlotte going off on Cole and eventually walking out on the interview. Ric follows suit and all seems to be well by the end, but there are at least signs they could be thinking of splitting the two up.
