Actually, Caroline plays a fairly important role aND matt was the reason for elena becoming a vampire and without elena becoming a vampire, a lot wouldn’t have happened so matt is relevant
Ah yes, the very important Elena vampire plot where she becomes even more dead weight and is more useless than she was as human. And it’s not like there were a thousand other ways that could have happened WITHOUT MATT *insert sarcasm*. He is sooo relevant.
And Caroline when she’s not a Klaus distraction she the glorified babysitter for plot hole characters. That makes her so relevant like I don’t know how the plot could have went on without. It’s almost like the show would have been better without her getting an unnecessary amount of screentime contributing absolutely fuck all to the overall plot.
For more information on why they’re irrelevant read here, here, and here.
