What exceptions can you point out? Do you mean for example, like they can choose to believe an imaginary character is "real" to them if they want to?
Like I said, I'm not against people having an imagination for an imaginary person in this case. People choose what they want to believe or see as real to them in their life, just like I see Timon as a friend to me. "Fictional" doesn't automatically mean that something is fake which I find is a common misconception.
So I don't think someone seeing Kion as "real" to them means it's the end of the world at all. It just means that they see this differently (just like some do about Santa Claus) and I think this really also depends on the context of the character as well. So I'm sorry if any of my statements sounded dramatic or not very clear in any way.
But I just won't agree that a 5 year old is capable of knowing everything between reality and imagination is all I'm saying, because of my own experiences.
