The day Sherlock jumped from Bart’s, John thought his world was over. He’d known other Omegas that hasn’t survived the loss of their Alpha. But John had never been a typical Omega. Even at the funeral, he thought he caught a bit of his Alpha’s scent, but of course when he looked there was no one there. At least his heats had never been that frequent. But the first one he had after Sherlock’s death he spent in misery and heartbreak, using toys in the bed where they had made so much love and his scent still lingered. As soon as the heat was over he moved out.
For the next year he threw himself into work. He could swear sometimes he could still feel Sherlock, like the moon pulling tides. But he’d seen Sherlock die. John chalked it up to the strength of their bond and tried to move on with his life.
In late January he had a particularly vivid dream. It was bitterly cold like only Russia could be. Sherlock walked in the darkness, bundled against the cold, following someone. John cried out as he saw someone about to jump him. Sherlock turned at his cry and knocked the knife from his assailant’s hand. John watched helplessly as three more men moved in on him. Sherlock tried, but they beat him unconscious, one of them picking up the detective, saying something to the others in Russian and tossing him over one shoulder. John woke, bolting to a seat. He put his hand on the bond mark, finding it warm. He shook his head, heart racing. Sherlock was dead. He’d seen him jump. He scrabbled his hands through his hair and went to take a shower, wondering how long his former mate would haunt him.
