I really like Frank - one of my favourite characters at the moment but, unfortunately, it looks like he's going to turn out to be a proper wrong-un.
Shame. I really like him with Megan.
Rebecca is pretty likeable, too. I don't know what her motivation for getting her family banged to rights is - is it common decency or is it purely spite against her sister?
Either way she's alright in my book if those guttersnipes end up on the wrong side of prison gates. Love her scenes with Robert, too. Sizzle!
