Schrödinger's (theoretical) experiment: An enemy Garen is MIA

The observer cannot know whether or not Garen is in the bush and consequently, cannot know whether or not he will be killed if he enters it. Since we cannot know, according to quantum law, the Garen is both in the bush and isn't, in what is called a superposition of states. It is only when we facecheck the bush and learn the condition of the Garen that the superposition is lost, and Garen becomes one or the other (in the bush or not in the bush). This situation is sometimes called quantum indeterminacy or the observer's paradox: the observation or measurement itself affects an outcome, so that the outcome as such does not exist unless the measurement is made. (That is, there is no single outcome unless it is observed.)

We know that superposition actually occurs at every elo level, because there are observable effects of interference, in which a single particle is demonstrated to be in multiple locations simultaneously. What that fact implies about the nature of reality on the observable level (Garen, for example, as opposed to entire teams) is one of the stickiest areas of quantum physics. Schrödinger himself is rumored to have said, later in life, that he wished he had never met that Garen.

Schrödinger's famous thought experiment poses the question, when does a MIA stop existing as a superposition of states and become one or the other? (More technically, when does the actual Bush stop being a linear combination of states, both empty and containing a Garen, and instead begins to have a singular classical description?) If the bush is facechecked, it can only be one. Our experience says that no bush can be both empty and containing an enemy; yet the bush, it seems from the thought experiment, can be such a mixture. Is Garen required to be an observer, or does his existence in a single well-defined classical state require another external observer?
