Gina didn't say to the others, "I just witnessed racism". I think that is what caused BB to call Jemima in and warn her. They certainly were scared as soon as Gina said that. Bear in mind, BB would have called Jemima in the DR straight away, but they didn't.
Who else thinks that she wouldn't have been warned if Gina didn't say that?
