It's the final episode in what's been a fantastic drama series, originally airing on the BBC a few months back and earning its lead Suranne Jones a well deserved National Television Award. Tonight however, is the night we have been waiting for. When we left things last week, Gemma and Simon were heading into what's bound to be the most awkward dinner of all time. We won't ruin anything but this is going to be one hell of a finale, as we see that Gemma has carefully devised a plan which will ensure her final act of revenge is as explosive as it can possibly be.
