Am I the only person who didn't notice the car at the end at all?
When she was "Daddy's girl" she was running around in a smart yellow car with a '58 reg plate. (They took Tom to school in it)
When she left for London as "Simon's pregnant mistress" they drove off in a tatty blue car with a '04 reg plate.
Taking the bus and moving to Middlesbrough would have been more of a sign of skintness
And what have you got against the place of my birth 2rebecca? 
It was despicable the way both adults used the boy to wage a war against each other - I couldn't agree more pinkfrocks, particularly when Simon committed his act of horrendous DV against her when he knew that Tom was alive. Simon was lashing out for frightening him by allowing him to believe Gemma had killed their son.

INTERVIEW WITH BERTIE CARVEL (SIMON) ON 'THIS MORNING'
Apparently the dinner party scene was shot over 2 days. It was 12-15 pages and the continuity was very difficult to get (hence they had to do it many, many times). Bertie Carvel said that Mike Bartlett was writing about real people who were morally ambiguous. All the characters were flawed, full of light and shade - including the neighbours and colleagues who were complicit in covering-up the affair. Simon was the 'villain' but his actions were borne from flaws in his character, possibly because of the low moral standards of his father.
Bertie Carvel said that he didn't feel safe out in public this morning with people shouting abuse at him!
