Yes, there are. In some fanfictions, the characters eventually understand each other better. They might have a heart - to - heart conversation where they realize that their differences were based on misunderstandings.

Molly Pitcher was a woman who showed great courage during the American Revolutionary War. She is often remembered for taking over her husband's cannon-firing duties at a crucial battle.
Yes, there are many Sherlock Molly pregnant fanfictions. Writers like to create this scenario to see how the characters, especially Sherlock, will react to such a life - changing event.

I'm not entirely sure specifically what 'Molly's Game' is about without more context. It could be the story of a person named Molly and some kind of game she is involved in, perhaps a personal game, a sport - related game, or a game in a more abstract sense like a game of life situation.
