Why didn't Violet and Cora push the other girls on Matthew?
I understand the reason is "storytelling" because they were the central couple, but what was the in-universe reason why Violet and Cora only ever tried to get Mary and Matthew married? It seems a bit odd to me: They didn't really know Matthew and his personal preferences in the beginning, but they immediately pushed Mary on him - the most arrogant and snobbish of the sisters. When Cora told Mary that marrying Matthew would solve all issues, Mary thought of him as some sort of uncultured peasant.
So what was their reasoning?
- Cora and Violet just wanted Mary to be the future Countess, no matter whom she had to marry for that (after all, that was the plan with Patrick)
- They thought no man could resist Mary and that Matthew would of course agree to the marriage (fair point)
- They thought Edith was too unappealing for Matthew and the thought of a match didn't even occur to them (poor Edith, lol)....but does it really make sense they immediately thought an Earl's daughter was not good enough for Matthew (a man they barely knew)? Did they really think nobody could potentially want Edith?
- Sybil was still a bit young (but not too young). But she always had good chemistry with Matthew (+ Isobel!) and didn't mind middle-class people
What I find particularly odd: Even after Mary rejects the idea of marriage and moves on to other suitors, they don't even mention the possibility of a match between Matthew and one of the other sisters.
