Little Goldfish

Sherlock Holmes isn't a goldfish, and those who aren't goldfish don't have problems. So why is everyone acting like he has? Perhaps it's because in the aftermath of his relapse and Moriarty's reappearance, certain... cracks are beginning to show. And even if he had problem... Why would some part of him seem convinced that Molly Hooper can help? That's the greatest mystery of all.
