 Tessa 's death was a turning point in Highlander : The Series . It marked the first time that a regular character died in the show ; it would be followed by the deaths of Charlie DeSalvo and Richie Ryan . Horvath recalled that " ... it changed the tone of the show . It made Highlander the show where you couldn 't be positive that the characters were safe because they were in the credits . " Tessa 's death also gave the show a pessimistic tone that influenced the remaining characters . Rosen explained that " ... in the years that followed without her and with [ Kirsch 's character ] becoming Immortal , ( ... ) you had to play the show differently . " Lineberger said that " Richie and Duncan relate to each other differently from now on , and Duncan is bereft of much of his joy [ and ] moodier as well . Tessa is no longer around to lighten him .
