Klaus saves Caroline during the battle with Silas but at a costly price.
Ringing pounded in Klaus' ears as he attempted to open his eyes gain his bearings. His eyes were iron weights refusing to open, trilling whizzing whistling past him as turfs of dirt flew up around him, disorienting him. A piercing wailing sound rent the air quickly followed by the sweet smell of blood. It was the announcement of death. The smell of blood anchored Klaus as he shook his head to rid himself of the stinging sound in his ears. His shirt was being pulled on, sending Klaus closer to the dirt as another series of whizzing sound sailed through the hair flying right where his head had been, something frying the top of his hair.
Everything rushed back to Klaus as he finally opened his eyes to see himself face to face with none other than his favorite baby vampire. The usual cheerful smile and twinkle in her eyes were gone, a terrified horror frozen on her face. Caroline's bottom lip was quivering her deep blue eyes searching Klaus' gray ones for something he didn't know.
Another series of blasts shot over their heads Caroline and Klaus were both pressing into each other trying to disappear into the warm earth below them. Caroline buried her face into his heaving chest, her nose rubbing on the skin peaking just of above the neckline of his shirt. Klaus pressed his body completely against hers, wrapping his arms protectively around her back and placing his stubbled face into the top of her matted hair.
The minute the scatter burst of shots ended Klaus rolled them over completely into the dense undergrowth, until he was back on top of her as her living shield. The thick vegetation covered them providing their only cover. Klaus held a finger over her mouth when she tried to part her pink lips.
Tilting his head so his mouth was placed directly next to her ear, he whispered, "Don't even breathe."
He made such little sound that he knew that Caroline was the only one who heard his demand. He pulled back to look into to her eyes to see that she understood. Caroline blinked her eyes up at him too terrified to move. The sounds of the battle around them stilled for a minute their sensitive hearing picking up a snap of twigs on the forest floor. Caroline froze her hands on his shirt, stopping the steady rise of her lungs. Klaus mirrored her movements, looking nowhere else but Caroline's panicked eyes. Her whole body was rigid as sounds drew closer to them and the flurry of magical blasts began shooting in all directions over their heads again.
Klaus saw tears forming in Caroline's eyes when more screams sounded off in the distance, Klaus closed his eyes in recognition of the screams. It was Kol's voice and it took everything in his power not to flash off and help his brother. Trying to focus on keeping Caroline alive he curled his hands into the dirt to keep himself from racing to Kol's pained howls. Caroline yanked him tighter into her, knowing the voice too. Tears were following freely now as the sounds of death and blood seemed to spell their fates. There was only one shot at this or the world would burn and them with it.
Klaus gritted his teeth, his target close enough now that he could hear the steady heart beat with little help from his vampire senses. The steady thumping of the human muscle was a beacon, calling out to him to focus only on that sound. But Caroline forgot to be still and drew a quick intake of breath pressing her chest against Klaus'. He widened his eyes to stop her but it was too late, a flurry of blasts shot over them, burning straight threw the green and grazing over Klaus' body burning the top layer of his skin.
He growled in frustration, the blistering burn already healing over but leaving a gaping hole in his clothes. Caroline was going to die if he didn't get her out of there. With all the speed he possessed, he yanked Caroline up and threw her as hard as he could, watching her sail through the air at an inhuman speed disappearing from sight. At least she would be safe now he reasoned. Klaus could handle her yelling at him for the stunt later.
A dark laugh sounded over his shoulder and Klaus whipped around fangs bared to meet the horror that had caused all the death around him. Klaus stood face to face with Silas the harbinger of death in the form of Shane the professor the doppelganger knew. Klaus let the fury ripple through him that he contained as he had held Caroline. Wolf instinct took over giving Klaus the senses needed to study his prey.
In flash of movement Klaus whipped out the bewitched dagger Bonnie had given him and stabbed it into the heart of Silas, crippling the immortal warlock. Klaus was not prepared for the black lash of magic as Silas' magic imploded on itself creating a sonic boom sending Klaus flying through the air. Twice now in the same hour, Klaus was knocked off his feet and lying face down smashed into the dirt. He lay there for a minute completely spent before climbing up to all fours and stumbling onto to his feet.
The surrounding area was totally burned, the blast radius of Silas creating a crop circle effect in the middle of the jungle. Klaus looked around surveying the damage, the smell of burnt wildlife overpowering any other scent. A devastated cry brought Klaus' head to the east and he could see Caroline zooming back into view. He was at her side in an instant but she was already bending over screaming down at the lifeless body on the ground.
"Stefan, no, no please." she was begging him, shaking Stefan's body but Klaus could see the stake jutting from his old comrade's chest and the ashen pallor of his face.
Klaus stood there shell shocked and emotionless, his friend was gone. Caroline was sobbing, dirt and tears marring her porcelain skin and Klaus just wanted to wrap her up again and shield her from the scene surrounding them.
The entire plan had blown up in their faces and that was what caused all hell to break loose. All the teams racing for cure ended up in the same spot and Shane used their anger against each other as a distraction to wake Silas. All he wanted was Silas to bring back his family and instead Silas possessed him. The first victim of the battle was Elena, Silas ripping her heart clear from her chest letting her body turn to ash and drift away in the breeze rustling through the trees.
After that was a blur of action and chaos. Klaus just remembers pulling Bonnie aside to have her bewitch a dagger while Kol tried to keep them alive. Bonnie struggled to keep a hold of herself but her power consumed her and Silas and the young witch began dueling with their magic. Caroline ran in to try to knock over Bonnie to get her out of the slippery pool she was drowning in but Klaus stopped her just in time, Caroline almost getting incinerated from a fiery blaze.
Now the blonde was crying over her the still, cold bodies of her friends the heart-wrenching sobs tugging at Klaus' heart. Her mewling pleas for the friends to come back grew as she raced across the blast radius finding Damon, Bonnie, Tyler, and Elena all lying with the lights gone from their eyes.
"Klaus!" she shouted in desperation.
Klaus turned slowly at the sound of his name not fully understanding he was still too in shock at Stefan crumbling away in the wind. She called his name again, fear and panic waking him from his stupor. Flashing to her side, Klaus saw her hunched over another body, one that Klaus knew too well. Drifting up the body Klaus was met with the cold dark eyes of his younger brother, dried blood splattered on his face.
Caroline was staring at Klaus trying to formulate something to say but failing to do so. Klaus crumbled to his knees whispering, "My little brother."
He buried his head into Kol's chest, clenching the fabric of the torn and bloodied shirt. Tears fell of their own volition, as Klaus screamed unearthly curses to the sky. Kol wasn't supposed to die; he was an original only the white oak stake could hurt him. A grief he had not felt since Henrik's death paralyzed him as he once again failed to protect his younger sibling. Klaus didn't know how long he knelt there in the scorched dirt over Kol's body but Caroline did not leave his side. She sat there knees curled into her chest, covered in specks of dirt with lips trembling and drowning in her own grief.
At some point Caroline crawled around Kol and gingerly put her hand on Klaus' shoulder. Klaus closed his eyes at the warmth her small hand provided, surprised by the comfort emanating from her. His need to be touched by her warmth consumed him and he grabbed her and pulled her into his lap. Caroline wordlessly kissed his cheek, her salty tears mingling with his and wrapped her arms around his neck, letting him bury his face into hers.
They didn't talk about what happened, they didn't talk about the fact thousands of vampires around the world were going to die, they didn't talk about the only reason Caroline made it was because Klaus saved her, or the fact that they hadn't seen Rebekah yet. They both knew they were the only two who survived the destruction and for now they just held unto each other grateful that the other survived.
