Character network The Sign of Three

Who meets whom in The Sign of Three?

The network shows all characters, except extras and very minor characters. The size of the dot (small, medium, large) indicates how prominent the character is in the episode. The thickness of the line indicates how many times two characters are in the same scene (once, twice, three times or more). Only on screen interaction counts. Phone conversation counts, but texting does not. All-characters-network-TSoT
