I wouldn't really know myself 😅 but there are some things in media that will randomly come up in my head and i'll be like "oh yeah i love when they write that kind of stuff!"
Recently i've been thinking on how sometimes the conclusion of a story where characters are at eachothers' throat is them meeting randomly and unexpectedly. This can seem like lazy writing, but if done well it can be really entertaining. I have two examples for you today, they are a boiling point in both stories so, spoilers ahead for Pulp Fiction and Jojo's bizarre adventure part 4.
Butch Coolidge meets Marcellus Wallace
So for context, by this point in the movie Butch has crossed Marcellus, they arranged Butch to loose a boxing match, but he went back on it for personal gain. So Marcellus has people looking to kill him. However things are looking good for Butch, he has an escape plan and everything, but his girlfriend left his watch back at his apartment. After we see how much it means to him, he only has to look for it.
So there's an extended scene of how he goes and looks for it, he's real sneaky while going to his apartment, and he strucks luck when he gets the upper hand on a goon ready to kill him. He gets what he needs, and gets out of there without much of a problem.
Normally that would be the end of it, but Tarantino is messed in the head so he likes to make things fun. SO he probably thought "What's the worst thing that could happen after all has gone so smoothly? What's possibly THE LAST thing Butch wants to see right now?" Tarantino gives it to him: Marsellus Wallace, the man that wants him dead, in front of him. They both take a moment to realize what's going on before Butch tries to run him over and Marsellus goes for his gun.
Josuke Higashikata Vs Kira Yoshikage
We go over context again: Jojo is a shonen, so anime baddie, yeah. He throws goons at the protags and they fight them off, possibly the plot progresses. Thing is Yoshikage has been sneaking from the protags for a while, and has known what they've been doing the whole time. The way he has gotten around is by stealing someone's face and living in their house.
It isnt until the son of the house, Hayato, notices Kira's not his dad that the plot progresses. Kira has gotten a new power that resets the day and can end all of his enemies if they find through Hayato. But for how convoluted it is, it's really satisfying seeing how the kid figures it out and makes attempts to stop Kira.
The protagonists are going to the place where the effect of Kira's power is taking place, the day resets so they keep going there. The thing that ends up happening is that Hayato sneaks a call to one of the protags so he will still go to that place but through a different route. By this point Kira thinks he's too powerful for Hayato to trick him, so in a careless joy rant HE says his real name out loud, just when the protagonist, Josuke, was arriving at the place.
The thing why i like this trope so much is because it removes all bullshit from a conflict, no preparation at all, just your strenght against your foe. While Marcellus and Butch wouldn't ever try to fight each other, and Kira and Josuke don't have all of their allies with them at the time, or the situation might not favor them, there's not a question to ask. There he is, you want him dead? Go.
