Alek snuck through the window with a practised finesse and stealth that would be envied by every cat burglar ever. He had no wishes to wake Cara  and most likely neither did Aconite.

As Alek brushed away the billowing curtains from around his face, his bright marvelling vampiric eyes instantly drank upon the scenery of the room, those two deep mesmerising pools of fierce determination froze time as they absorbed and took into consideration every minute detail available. 

Alec had an attention to detail on an extraordinary level that no human (and even most other vampires) could even fathom. 
It all locked away to memory. 
The indentations on the bed, positioning of posters and bed side clutter alike. The airflow of the slight breeze and the individual scents upon it. Carla, the fluttering of her eyelids, the decompression of her breaths, the colour in her cheeks. And Aconite.

Aconite the assassin.
Truth was Aconite wasn't what Alek was expecting. But seeing him standing over Cara caused an ill sickening feeling in Alec's gut. It burned within him like a diseased rage. 
Despite all his internal boiling spite and hatred Alec remained cool, calm and collected. He took his position with a casual grace, nonchalantly leaning back against the windowsill cleaning his nails as he talks calmly and quietly.

"You know, Aconite, on a different day I might have you address me differently, but no. Not today. Today you are truly dealing with a Dracula."

He chuckles softly as he looks up from his hands to grant the assassin a wickedly devilish smile. 

"Unlucky you!"

While calm and in control in his demeanour, Alek was studying every hidden detail for the slightest clues of what made this creature before him. His clothes, the stains, the weapons, his stance, posture, speaking pattern. All of it.

"You enjoy your job don't you." He whispers across to him. He rolls his eyes back as he opens his hands.
"And why wouldn't you!?" 

He takes a small step forward and points at the assassin.

"But if you dare kill my human..."
He lets the sentence trail off not having to say anymore. He lets him think about his extinction.

His arms fall to his sides as he relaxes and rolls his shoulders. "If you leave her now I will repay you with a five second head start. Don't waste it." Alec growls excitedly as his fangs snap out with a warning snarl.

"Run, run, runaway!"
"Live to kill another day."
