It's pathetic the way she seems to view Matt as her role model for being human so she'll let him constantly walk all over her, exactly the way he once condescended too and dismissed Caroline! Urgh I really dislike the writers blind spot for that character, he is such a judgemental douche, yet the way the show presents it he's the most pure and wonderous human being ever

And urgh if Elena does kill Katherine I am very likely to just skip next season entirely, unless I hear REALLY good things about it. It's not like the actress isn't available lol, so it would be such a waste to not keep Katherine around for an occasional visit each season
