Not Broken, Just Bent

John returns from the war and suffers from severe PTSD and Depression. Being uncooperative, John is sent to a mental hospital, where he meets Sherlock, the brilliant but troubled dark-haired patient in the room across from him. Both have pasts that should be left alone, and both are suffering in ways that they thought nobody could possibly understand. Will they be able to find solace in each other in such a place? Or are they truly as broken as most make them out to be.
