1. In the example at hand, a possible solution would be to separate the mechanics of how the episodes aired from the content of the story itself. You don't need story details to have an explanation of how Season 5 of Breaking Bad was broken into two pieces that aired a year apart from each other.

2. The fact that a major character dies, is pretty arguably a spoiler. Obviously not for stories so common and/or old that they are tropes (e.g. Romeo and Juliet). Coming back to the example of Breaking Bad Season 5, knowing that a major character dies is probably universally accepted as a spoiler within the first year or so after it airs.

So how far do you go back? And for what countries and, indeed, cultures? Note that English Wikipedia is not American Wikipedia, but pretty much International Wikipedia. The world is a very big place. You still seem to be assuming I've asked you for "something obviously acceptable people like me", and that's not the case at all. What's a rule for people who are from somewhere that couldn't even tell you who Baba Yaga was, let alone a story about her?
