Another's Happiness

Molly and Greg are set to marry in a few months time. However, when old feelings and past relationships are rediscovered after a mysterious kidnapping incident, emotional confusion begins. Molly/Lestrade, Mystrade, Mary/John (barely), hints of one-sided Johnlock, and a bit of smut, all mixed up in a big bowl of angst. Open-ending. Complete. I'm so sorry.
