In the final scene of Scarpetta Season 1, someone walks through Scarpetta’s door moments after she kills Officer Ryan. The episode cuts to black before revealing who it is, leaving the identity intentionally unresolved.
Based on the final shots of the episode, two characters stand out as the most likely possibilities: Maggie or Blaise. Maggie is shown gathering files for Scarpetta during the final montage, suggesting she may have been heading to meet her. Blaise had just called Scarpetta after discovering Officer Ryan’s connection to the Thor experimental skin graft program, but the call cuts out before she can finish explaining what she found.
Some viewers have also suggested Elvin Reddy as another possibility, although the episode provides less evidence that he was nearby at that moment.
This video breaks down the full investigation behind the ending, including the three separate cases that unfold during the season.
