"Caroline is dating kol and try to help silias when the gilberts kill him, she goes for revenge. she and the originals try to find a way to take advantage of the other side being down to bring him back." –P.M
I tried but...it's not my best I admit to that. Still, I hope it's alright.
Caroline looks down at the scorched body and feels empty, so many emotions passing through her that she ends up feeling hollow at the end. She wants to make someone hurt, she wants to do anything to make this hollowness inside her disappear. She wants someone to feel what she feels. And she wants it to be Elena and Jeremy Gilbert.
Elena spouts all sorts of excuses but none of them she wants to hear. She wants Klaus to make them suffer, she wants them to burn. She wants anyone to get in the way of avenging Kol to burn. She snaps Bonnie's neck without remorse and lets Klaus tear the Gilberts to pieces, their blood decorating the walls and floors of their home.
But still with them gone, Kol isn't back and she looks in despair at Klaus who is on his knees on the floor, hands bloody and crying out in anger. He understands perfectly. Kol is still gone. And all this death is only a temporary relief.
With the Gilberts gone and the only map to get to the cure gone, the Salvatores are furious but Klaus who is tormented every second by the Hunter's curse takes care of them. He talks to himself and disappears for hours at a time, his already damaged mind cracking from the horrible visions he sees. He tells her sometimes at night when he can let himself be vulnerable and she shudders as he describes to her what he sees.
She undaggers Rebekah on an especially bad night and even as furious as the girl is for being daggered, she swallows her anger and comforts her brother as he screams at something only he can see. On another bad night, Caroline calls Elijah. The eldest Original arrives one night and Caroline watches the small family in the parlor, talking about days of horses, playful swordfights and their humanity all so long ago.
The dynamic in this house is like this, the four of them trying to live with the sorrows that haunt all of them before it all stops almost half a century later. And as Silas roams the earth and destroys all he can find, The Other Side starts to fall apart and Caroline imagines Kol crying out for her. They find a young witch, a relative of Bonnie who performs a spell and Kol finally returns to them.
They're all staring at him, relieved and disbelieving all at once and he laughs at them. "Why are you all so glum?"
Caroline laughs but its stained by tears and he pulls her into a hug and breathes in the scent of her hair. "Don't cry, Forbes. I've returned to you after all."
"I'm happy, that's all." She holds him tighter, never wanting to let go again. "I'm happy you're back."
"Well, so am I." He grins at his siblings behind them, watching. "So am I. Very much."
