Single Proposition: Unlucky Childhood Friend

Merge Unlucky Childhood Friend with Victorious Childhood Friend into a third trope with a different name

Pros

The characters are the same in both cases and have no real substantial differences.
UCF's name is based on the faulty premise that the character type usually loses.
Either trope being listed on a page is automatically a spoiler, especially VCF.
Many characters can be both or either of the two, like Left Hanging endings, or Multiple Endings with video games.

Cons

The story's tone often favors one of the resolutions (Victorious or Unlucky), resulting in different plots and treatment of the childhood friend character, depending on which outcome it's moving towards.
