I am in 2 minds as to whether Rob just got lucky there or whether he set Henry up to tell Helen.
Worked out well for him though
Ursula though, her motivations are, to me, not as machiavellian as they might seem.
She made it clear by siding with Jess that her main interest in Rob is a df to her dgc.
She wants Henry out of the way to clear the path (not directly to abuse Helen but because she doesn't give a flying fuck about the wife of the father of her dgc).
She could see the plot had been rumbled. If she said oh yes Rob and I were planning on sending H to a lovely private school.next month she looks like an evil duplicitous cow.
So she lied to cover her own arse. She needs to be in a good light to maintain access to the golden gc.
Plus she thinks thete is fuck all wrong with sending a troublesome child away. She did it with her own son. (That rather than education seemed to be her motivation when she and Rob talked about it).
Plus she doesn't know Rob told Henry so she would have to assume they were overheard.
So she barely lied at all.
We discussed sending H to school - true.
He must have overheard us - also true as far as she knew.
She and Bruce were offering to pay - also true although note she appears to have made that important decision without even consulting him.
Helen is erratic - she has been a bit irrational.around Ursula - with good reason.
I think Ursula is mostly interfering, overbearing, self serving, narcissistic and cold. I don't think she is volluding with Tob directly just protecting her own interests vile bitch.
