Tear Jerker / Highlander: Endgame

• Connor's death where he commits a Heroic Sacrifice by forcing Duncan to take his quickening so he can become strong enough to defeat Kell. Throughout the scene, Duncan does everything he can to prevent it from happening, insisting that another way can be found and pleading with Connor not to force him to break their bond, only for the latter to mournfully whisper that it has to end with his death. It all ends with this last exchange:
  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.
  (Connor smiles and nods.)
• Ahead of Duncan and Kate/Faith's wedding, Connor recalls once walking in on Heather using a knife to cut off some of her hair. She looked fairly bloody and pained, so he asked her why she would do this.
  Connor: She said it was the one part of her that would never age; it would forever remain the same as when I first fell in love with her. That's how she wanted me to remember her.
• Duncan burying Connor next to Heather.
  Duncan: I hope you've found peace, my friend.
