Really enjoyed Kirsty's nasty jibes to Tom.
As for Helen, it might be more gaslighting but he's perfectly capable of just saying to Helen 'Darling, you're looking very tired. Are you sure you're up to coming out tonight and going to this tiresome meeting? And how about Henry, is it really fair on him to drag him out again after a long day at school? Wouldn't it be better not to upset his routine and get him to bed here at the normal time. You stay with him and I'll go to the meeting. I can update you later. There's nothing that really needs your input at the moment, is there?'
Helen listens dutifully and another little bit of her soul dies. She nods and says yes, she is tired. In spite of herself, she looks unhappy. He presses further and asks if she has a headache. She clutches this straw and says yes, she has a headache. Yes, it would be best to stay at home and not see her family and not tire herself out further discussing her own business venture. Yes, she will get Henry to bed and then have a long bath and an early night. (In her head she is thinking that this makes it a lot easier not to have any supper, so it's a good thing really.)
Rob says 'After all, darling, we've got to think of the baby. I just want to look after you and our boy. It's the sensible thing to do, I'm sure you can see that. I'll tell the others when I get there. Now, off you go and make sure not to overdo it!'
