Anyone who wanted to read Pieces of the Puzzle purely for what the OP was requesting (Brian has a heart secrets coming out) could just read the first four chapters, and it would be like a nice standalone. Or possibly through Ch. 7, because the last section of chapter seven has a B/J Truth or Dare game that reveals some more. After that, it becomes a rape fic (starting Ch. 9), and after that, a BDSM fic.
