Who has Mrs Hudson, Greg Lestrade, Molly Hooper and Mycroft Holmes met?

A while ago, I made network maps showing who met whom in each episode of BBC’s Sherlock. I wanted to explore the individual characters as well – who had actually met whom throughout the show? I decided to focus on Mrs Hudson, Greg Lestrade, Molly Hoope and Mycroft Holmes, since they are present in most of the episodes but they don’t usually get much screen time. Perhaps a visualisation would show some surprising connections that I had missed?

The tables show everyone that each character has met, except extras and very minor characters. Only on screen interaction counts. Phone conversation counts, but texting does not. Fantasy sequences count as if they were real, for my sanity’s sake.
