Prompt: Threat
"Why did you kill him?"
Esau smirked, pleased to have ruffled Jacob's feathers for once. "I was bored."
Arching one eyebrow, Jacob said, "There's a whole island for you to wreak havoc on, yet you choose a child?"
"Just passing the time, I suppose." Usually only Esau longed to hurt the other man, draw blood or elicit a groan of pain—yes, those desires fueled the man in black, and fury was his domain.
But today, he reversed their roles by some marvelous twist of fate. Who could have guessed how much Jacob liked the little pests? Esau's grin widened as he noticed the muscles in Jacob's jaw tighten, his sharp blue eyes narrowed. Glancing down at the child's corpse, studying every inch of the pale face smudged with dry blood, Jacob said, "This is the last child you will kill." He did not plead or even kindly request it, but rather demanded it.
With that heavy-lidded, bored expression that his counterpart so often wore, Esau said, "Oh, and why is that?"
"Because the day you do will begin an eternity spent only in the form of the smoke monster."
"Don't make me laugh with your empty threats, Jacob."
"That sounds a lot like what you said the day you were sentenced to this Island," Jacob replied, so softly that the chatter of the others approaching the beach nearly drowned out his words.
Stunned, Esau opened his mouth to yell, to shout back some angry retort, to curse his captor with the worst insults he could think of. But with Jacob's pets nearing their location, Esau knew he had to make himself scarce at once. As much as it pained him to do so, hiding his true form was just another one of the orders that he had to follow, lest Jacob's words become more than just empty threats.
AN: Is there any character category for Esau/MIB/whatever? I couldn't find one, but I would so love to include him in the main characters, since this is titled after him and all.
