Saw the e4 episode yesterday - Kathy was at it again, i get the feeling that more of Kathy's past will be explored due to how she is behaving which connects to the swimming and also the men she had in her life.
I cant believe Kathy would do anything to keep Rhys away from Sarah, and she would risk her marriage and her daughters, just to get Rhys out of Sarah's life.
What do you think???
