Sherlock Season 4: 9 Big Questions After 'The Lying Detective'
8. Have We Seen The Last Of Mary?
After the death of Mary Watson last week, it was expected that we'd seen the last of Amanda Abbington on the show.
However, she made a return this week as a vision of Watson's, serving as a means to help him deal with his grief, guilt, and anger. Serving as his inner monologue, it was an effective way to bring the character back and help progress the storyline.
At the end, though, it seems that some degree of closure has been found, and Mary can leave John behind. Does that mean we've now definitely seen the last of her, or will her vision be popping up again next week?
