I know I've not watched it for a while, but what's happened to B & H? Last I saw, they'd just handed over Petal to foster parents. Honey was just talking about taking someone swimming, presume Petal (?).
They were gonna give her up for adoption but in the end Honey couldn't part with her and they re-named her Janet, after Honey's dead mother i think. And yeah, thats who she was talking about going swimming with.
