Well, I'm glad to see they've added a bit more to the story than just Kathy suffering at the hands of an abusive and controlling husband. If their lives really are in danger then I can understand more now why she left Ian and Ben.
Kathy should be proud of herself for walking away, but it's like Phil said, "It's only just beginning". Men like Gavin never let those they consider their possessions go, and EE warned us that he's gonna be one of the darkest characters we've seen in a long while.
So I guess Ronnie has finally made a decision over her marriage. I can't say I'm surprised, as it didn't look like she had any feelings for him for a while.
