The moment his airway was free of whatever it was inside of him, Klaus sucked in a ragged, shuddering breath as his lungs worked in overtime to provide oxygen. Just because lack of breathing didn't kill him didn't make his body any less inclined to crave it. Klaus stood still in her grasp, no longer attempting to escape and instead, waiting for this encounter to slowly take a turn in his direction - as things always did. Patience, while not his favorite talent, was something he was quite good at employing when necessary.
"Not just a vampire, love," he corrected venomously. Anything else Klaus had intended to say evaporated instantly the moment he recognized Caroline's features as they morphed before him. Fury overtook him then, because the sheer thought of this abomination even copying Caroline's features filled him with anger. He roared, pulling all of his strength into attempting to rip away from her. It was an affront to Caroline's grace and beauty, to be so replicated by something so vile.
"Beware your intentions," he growled, voice now quiet. "If you think to subdue me with parlor tricks, you'll be disappointed." There was little to rile Klaus up more than to prey on his attachments to his loved ones - it was a mistake to allow that information to slip with his reaction to Caroline's likeness. But it was one he could handle well enough.
