Hi! I don’t know if anyone told you, but the Pride & Prej series you watched is actually the best adaptation of the book, because unlike in the movies, they actually put the entire book in there. AND, for the Lydia thing: after Elizabeth marries Mr Darcy, Lydia asks her all the time for money, and Lizzie gives it to her, taking it out of her monthly personal expenses budget. And Wickham loses interest in her and their marriage falls apart. But Lizzie and Darcy stay happy and everything.
