in consequence of the missive, Lucy and blame, penned by Mary Anne
I think this means that Elinor felt persecuted, being in the company of a woman engaged to Edward. And Lucy always spoke of Edward.
Earlier Elinor too takes pains to be with Lucy to find out more about her relationship with Edward.
So I don't think why Lucy shouldn't do the same. Even more so as 'she' is engaged to him. But I doubt if she was deliberately 'cruel' to Elinor. With her she had to be on friendly terms to find out things.
She was cruel to Marianne yes, whose attitude towards Lucy was also been nothing to sing about :)
