Context:

In the world of movies and TV shows, it is not uncommon for key characters to never share a scene, despite being central to the plot. Iconic pairs like Doc Brown and Biff from 'Back to the Future', Jesse Pinkman and Walt Jr. from 'Breaking Bad', and Luke Skywalker and Darth Vader in 'Star Wars: Episode IV' are examples of characters who never interact directly. This phenomenon extends across various genres, from fantasy, as seen in 'Game of Thrones' with Ned Stark and Tyrion Lannister, to superhero flicks like the Marvel Cinematic Universe where Steve Rogers and Pepper Potts never meet. Such narrative choices highlight the intriguing dynamics of storytelling, where even without direct interactions, characters can profoundly impact the narrative and audience experience.

Dive Deeper:

• In 'Back to the Future', despite Marty McFly interacting with both Doc Brown and Biff, the two never meet in the first movie, as Doc is mostly away from the school setting, which could have otherwise facilitated their interaction.

• Jesse Pinkman and Walt Jr. from 'Breaking Bad' never share a scene together, even though both characters appear across all 62 episodes, highlighting a deliberate narrative choice that reflects their separate story arcs.

• In 'Star Wars: Episode IV - A New Hope', Luke Skywalker and Darth Vader, the central hero and villain, do not meet on screen, with Luke only becoming the clear protagonist later in the film and Vader having limited screen time.

• Ned Stark and Tyrion Lannister in 'Game of Thrones' never interact, despite both being significant figures in the early seasons, which is consistent with the original book narrative and Ned's inherent distrust of the Lannisters.

• The Marvel Cinematic Universe, known for its vast array of characters, surprisingly never features a scene between Pepper Potts, a crucial part of Iron Man’s story, and Steve Rogers, 'The First Avenger', a gap that showcases the complex web of relationships within the franchise.
