And it's sad that Caroline herself has been made to feel that in a way, there's mentions of how she likes who she is now more and doesn't want to be human again, but being a vampire only made her physically stronger! It just seemed like characters like Damon started respecting her more once she could kick his ass, it was only then that they started to appreciate her more, and so that made her feel like being a vampire has significantly changed who she is

And idk, all I can think is that it's because Matt has been a pretty supportive friend to Elena and Jeremy, but still as a character in his own right he comes off as having a real chip on his shoulder IMO
