Yes I know all this history with Debbie, but she's known her dad long enough now, and like you said he's been very loving dad in recent years. Her childhood hasn't been very stable one, so she's not used to that. And she has her Dingle genes! :D But what I meant is that Ross and Cain are very much alike on how passionate they both are. They go to extremes in trying to protect their loved ones.
I don't like how Cain treats his little son at the moment..similarities there too with Ross.
