Tear Jerker: Highlander

  • Heather's death with "Who Wants To Live Forever" playing in the background.
  • Pretty much all the main character deaths of the series.
    • Tessa, killed at the very beginning of Season Two in a completely senseless death by a mugger, just after she and Duncan had decided to get engaged.
      • All the more so, since Duncan proposed to her immediately after remembering a gypsy telling him that he would love many women, but never marry. In an attempt to Screw Destiny, Duncan may have actually cosmically caused Tessa's death.
    • Darius, the kindly immortal priest, was murdered in his own church after centuries of forswearing The Game and doing no harm to anyone.
    • Richie is killed at the end of Season Five by Duncan himself after the demon Ahriman tricks them both with illusions into fighting a duel against each other.
      • The worst part of this is the immediate aftermath. After Duncan kills Richie, he endures the quickening but at this point both he and the audience are still unsure whether he killed Richie or demon!Richie. He calls out Richie's name uncertainly. Richie steps out from behind a pillar nearby... and then smiles wickedly.
    • The scene is made even more painful by Joe breaking down in tears at the sight and Duncan demanding Methos(who turns away in disgust) take his head.
  • The It's a Wonderful Plot shown in the series finale presents cases for the majority of the supporting cast when they didn't have Duncan there to influence them. Horton ends up taking control of the Watchers and ruins their sense of morality, leaving Joe without any hope for humanity, Methos loses one of his great loves and ends up rejoining Kronos to wreak havoc on society, and Amanda ends up degenerating into a more deadly life of thievery, eventually killing off a rich spouse of hers before getting gunned down and decapitated by a group of Watchers. Even characters that died during the run show, like Tessa and Richie, are shown to have lived unfulfilling lives, with the latter eventually suffering just as unfortunate a death as in the main timeline.
  • Connor's death in Endgame.
    Connor: One of us has to die now, old friend
    Duncan: No.
    Connor: And you know it.
    Duncan: No.
    Connor: Good-bye, Duncan, my true brother.
    Duncan: I love you, Connor.
