sherlock/inception crossover: sherlock’s gone to deep, too far caught up in his dreamscape, his wars and his urban battlefields that he’s forgotten what’s real; even forgotten where the dream began. it’s an endless world of cases and it’s perfect for him: able to do experiments and never permanently injure anyone. john had warned him, told him about the dangers of too many levels of consciousness and all that, but sherlock wouldn’t be sherlock if he had listened. mycroft wouldn’t normally involve himself with minor retrieval cases, but this is his little brother we’re talking about and nothing is going to stand in his way. they’ve got the best team on hand, and they are going to get him back, no matter what.
