Samantha Miller (H1)

Samantha's DNA was taken by an unknown source and was used to clone her. Her brother forced her to stay with Sherlock Holmes and John Watson for at the time an undisclosed amount of time. After finding out that she had a clone she faced the clone and Moriarty in a highrise. In the ensuing fight, a full-length mirror was shot out and caused the clone to almost fall to her death when Samantha grabbed the clone's wrist and was able to pull her safety while also causing herself to fall to her presumed death.

Her body wasn't found at the bottom of the highrise and is presumed dead.
