The gothic man had been locking himself up at the thatched cottage. Up to the point before the revenge started, Harith would not deny being hesitant with the plans. Even when he openly leaked out his identity and that bloody Purist to Sara, he was already wavering.
It made it even harder for him when Sara denied it wholeheartedly, making a thousand excuses for her husband. If he could, he would have stopped there. But it would be a waste to let go of such a perfect opportunity.
However, when Lucas called him that night and was looking for Sara, putting aside worried into one corner, he was feeling a plethora of happiness. Too excessive that it felt forced. He knew that there was no turning back. It was him trying to make a rational judgement on his self-centred action.
