According to our Spoiler Policy, there should be no spoilers, marked or unmarked, in the description. If the description is a spoileriffic plot summary, it needs to be cut down.
I'm bad, and that's good. I will never be good, and that's not bad. There's no one I'd rather be than me.
I don't know if it is the case, but how about First-Episode Spoiler? Sometimes one plot twist in the very beginning of the show is fundamental to explaining the overall plot. In fact, some times, even the official summary of the show does spoil that part, even if the show itself treats the "spoiler" as a twist.

There is currently no official policy in that case. A strict reading of the Spoiler Policy says that they should be there, but by the nature of First-Episode Spoiler, it's often impossible to properly describe the series without it. (See Ouran High School Host Club for an example of this.) It's probably best to include such information only if it's essential. In the case of Ouran, the spoiler sets up the premise for the rest of the show. On the other hand, the spoiler from the New Jedi Order series of novels is a huge spoiler in the context of the greater Star Wars Expanded Universe, but has pretty much nothing to do with the premise of the series and is more about setting up Anyone Can Die. I would include the spoiler from Ouran in the description, but would edit out the one from the NJO.

The article can't decide if it wants to use spoiler-tags or just assume that It Was His Sled. We should either rewrite the description completely so it doesn't contain spoilers and then add spoiler-tags to examples or simply remove spoiler-tags completely because everyone probably knows it.
