Howver Hatfield [[ScrewThisImOuttaHere decides]] the Confederacy cannot win and decides to head home. When confronted by McCoy Hatfield tries to get him to come home as well. McCoy refuses but allows Hatfield to go home, ending their friendship. Not too long afterwards McCoy is captured and spends the remainder of the war in a prison camp. Meanwhile Hatfield has returned home and prospered in the intervening time. Over the next three decades the relations between the two families degenerate into armed conflict, with Hatfield wondering where he and Randall had gone wrong after so much death and destruction.

* This is what happens to Anna and Elsa in ''WesternAnimation/{{Frozen|2013}}.'' Elsa shuts Anna out of her life and refuses to play with her. Anna is convinced that Elsa doesn't love her anymore. However, Elsa did this because she wanted to protect Anna from [[IAmAMonster herself]]. This is because Elsa accidentally almost killed Anna with her powers when they were playing, and Anna doesn’t know this because Grand Pabbie altered her memories so that she doesn’t remember Elsa’s powers so he could heal her. During an argument between the two at Elsa's coronation, Elsa loses control of her powers again, forcing her to flee and causing Anna to realize what Elsa had kept hidden all these years. However, Anna [[TheDeterminator refuses to give up on Elsa]] and continues to [[ThePowerOfLove love her]], believing that they can once again become friends. [[spoiler:Anna even goes as far as making a HeroicSacrifice for Elsa, and saving herself from her DisneyDeath since this was an ActOfTrueLove. After Elsa realizes that love fixes everything, [[HeterosexualLifePartners they reconcile and eventually becomes best friends with Anna]].]]

* ''Series/GameOfThrones'':
** Robb executing Lord Rickard greatly fractures House Karstark's ties with House Stark. Catelyn freeing the murderer of Lord Rickard's children probably did not help.
** Jon allowing the Wildlings to go South of the Wall pisses off House Umber's new Lord so much that he allied with the Boltons despite hating them.
