Should all characters get along? #writetip. Definitely not. But why not spice up a scene by forcing two characters who don’t get along into a situation where they must.
Put their lives in danger. Make them rely on each other. But the whole time, they really can’t stand each other.
Then give a character a life altering decision. Character A must risk their lives to save Character B. Do they do it? Or do they leave the person to die. This will say volumes about your character, and maybe scare your reader at the same time.
Farley playing with the cat made me think about odd pairings and how sometimes life surprises you, but also how fiction should surprise you.
