Lavinia should have ended up with Carlisle

Rather than killing Lavinia, who was such a greta character, she should’ve ended up with Carlisle. Maybe her exposing her uncle was because of her father’s debt and maybe she admired Carlisle. After they meet again at Downton, they spend more time around each other. They discuss Mary and Matthew, both realize that they are in love with each other and in the process fall for each other. Carlisle and Lavinia would’ve been a great couple, he would’ve mellowed down a bit maybe
