LyndaNotLinda, thank you, he was in Teachers, I'm couldn't remember where I knew him from 
Anyway, back to the plot, haven't a clue now what is what, I presume she got the tablets for mil, she told mil her and her son would be fine financially so she could pop her clogs with no worries.
I'm not convinced Kate had a termination, I think her and the bar girl will be good friends and bar girl will tell her that Dr Foster set her up to get to know her.
I do not like Ros, is she meant to be funny, she isn't.
I hated the scene with Gemma and accountant, I think I know why she did it but she could have black mailed him another way.
Sorry, I'm not contributing much to the theories, I will watch it till the end though, because I really want to see what happens.
