Heartwarming / The Mystery of Edwin Drood

• The moment Helena "thanks" Septimus by kissing his hand.
  Septimus: Tut! I am much overpaid.
• The echo of that scene at the end of the BBC version, as they are sitting together on a garden bench.
  Septimus: Did I just ask you something?
  Helena: No ... but I said yes anyway.
• After finding out from Mr. Grewgious that her engagement is not inescapable after all, Rosa hugs him. His bewildered, but happy reaction is completely adorable.
