All this being said, even with their ups and downs, it's clear that Elena and Caroline have one of the best bonds in The Vampire Diaries and there are plenty of emotional and funny quotes that prove just that. They may not have always seen eye to eye, but it's only because they cared about each other too much to let them hurt themselves or others.

Caroline Wants The Hook Up Details

"I Mean, Elena, We Are Your Friends. Okay? You Are Supposed To Share The Smut."

Caroline says this quote after Elena goes on a date with Stefan. Though she was originally jealous of Elena's effect on the Salvatore brother, she's still her friend and wants to support her. Her asking about the specifics is just another way of showing that she cares.

Though Elena is still a little standoffish about sharing much with Caroline for fear of hurting her, she appreciates at this moment that her friend just wants to listen to her and is putting aside her own feelings to show joy for Elena.

Elena Tells Caroline She's Right

"Everything That You Were Saying Was Right. It's Just Hard For Me To Hear, You Know? You Were Just Being A Good Friend."

Elena says this to Caroline a little while after they have a fight about Stefan. Though Caroline isn't jealous anymore, Elena believes that Caroline is trying to get intel on her relationship with Stefan for his evil vampire ex, Katherine. Caroline then tells Elena that she's not been a good friend lately because she's been focused on Stefan.

Though Elena has every right to be upset with Caroline, she just tells her she's right and she's happy that her friend is watching out for her even though it might not be in the way that she wanted. This also helps Elena gain some perspective that maybe her friend just misses her.

This quote only further shows that Caroline is a committed and loyal friend who believes in the "Girlfriend Code" and wants to maintain her bond of trust with Elena because she means that much to her.

"You Have To Admit That You're Kinda Just Letting Your Life Pass You By. And Isn't Stefan The One Who Wanted To Make Sure That You Lived It?"

Elena and Caroline talk in The Vampire Diaries.

Caroline says this to Elena when she becomes obsessed with finding Stefan after he trades his servitude to Klaus for his brother's life. Elena can't stop thinking about Stefan and barely enjoys her eighteenth birthday party because of it.

Caroline is being such a good friend here because she uses the thought of Stefan to persuade Elena to enjoy herself and stop putting her life on hold for an immortal guy. She bluntly tells her friend to start living again, which is exactly what Elena needed to hear.

Elena Won't Turn Her Back

No, Caroline. It's Not Okay...None Of You Asked For This, But Who Would I Be If I Just Turned My Back On Any Of You?"

Caroline feels this because she was turned by Katherine, and Elena just makes sure to tell her in this moment that she knows that was unfair. At the same time, Elena also states that she will always be there to help out Caroline. She will never let her own sorrow get in the way of her friends' happiness.

Caroline Voices Her Opinion

"I'm Sorry, But Stefan Is Your Epic Love. And I'm Not Going Down Without A Fight."

Caroline looks concerned on The Vampire Diaries

Caroline says this to Elena when she is struggling with her romantic feelings towards both Damon and Stefan. Damon did some of the worst things to Caroline and so she's just trying to protect Elena from suffering the same fate.

What makes this even more representative of their friendship is the fact that Caroline listens to Elena's feelings, but she acts as her friend's voice of reason when she really needs it. It just shows that she pays attention to how Elena feels when she's around Stefan or Damon.

Caroline Intervenes

"Fine, Friend-tervention. I Think Your So Called "Feelings" For Damon Are Really Starting To Cloud Your Judgement And I Don't Like It."

This quote is from a scene where Elena is irrationally happy and in love with Damon in a way that kind of freaks Caroline out. She later learns that her best friend intuition was right, because Elena was sired to Damon when she turned.

Not only is Caroline a very observant friend, but she's not afraid to tell Elena when she's being a bad friend in return. She loves Elena, but she also wants her to see how much being with Damon has changed her personality, and not in a good way.

Caroline Doesn't Give Up

"Because We've Been Friends For Forever...I Am Not Going To Give Up On You."

Elena and Caroline go to college in The Vampire Diaries

Caroline says this to Elena when her humanity is turned off and she does some of the worst things imaginable to the people she cares about. Not only does Elena hurt Caroline's mom and terrorize innocent people, but she also doesn't want to turn her humanity back on.

With all this in mind, Caroline still says she will not give up on trying to get Elena back to her normal self. She's faced her family members and close friends hating her before and so she wants to make sure that Elena never has that happen to her.

Caroline On Being Best Friends

"The Day That I Stop Telling You [How I Really Feel] Is The Day That We're No Longer Best Friends, And I Hope That Day Never Comes."

Caroline says this to Elena after giving her a piece of her mind. Again, though she may be a little passive-aggressive with how she voices her concern, she does it because she truly cares about Elena and wants her to make the right decisions in her life.

This is one of Caroline Forbes' best quotes because she admits that she can be rude, but it would be worse if she didn't say anything at all. Their friendship is not like Elena and Bonnie's. It's built more on trying to challenge each other to be better people.

Elena's Wish

"Take Care Of Everyone While I'm Gone, Okay?"

Elena says this quote to Caroline while inside her sleep spell that will last Bonnie's entire lifetime. She knows that she is going to miss out on a huge portion of her friends' lives, but she trusts that Caroline, as the nurturer she is, will make everything okay.

Elena knows, more than anyone, that Caroline is determined and she deserves to live the problem-free life that she had before the vampires arrived. Though that's not entirely possible, she knows that Caroline is the only person capable of keeping in touch with the people she cares for most in the world.
