not always, you see, first that it's been merely stated as an hypothesis not confirmed. there's only so many ways certain things can play out after all. Once you have enough experience with how stories are told. You will be able to figure out possible outcomes. If it is a super hero movie for example, you know by the end of it things will be okay or lead in to a sequel.
the definition of spoilers is too loose. for me a spoiler is information that changes your perspective of the story being told. You tell me minotaur hotel is about a minotaur, well duh. you tell me Nikos is putting an act, now that is a spoiler (but only if you know who Nikos is supposed to be, otherwise it's an obsolete bit that won't be relevant until you know the spoiler yourself)
