Kids have a fascination with being a character in a TV show, they will literally go to war with siblings and friends about who’s the fairy princess with blonde hair.
You’ll say stuff like, “you’re both both the warrior princess.” Or “can’t you both be the homeless bum?” But that’s not an option.
They must inhabit the thing with avengeance, become the character or object like the trained character actors they are.
That’s a good point too, it’s not always a human or even animal character, sometimes it’s a thing, always something pivotal to the plot, but non the less it can be a thing.
Perhaps they see the inherent value in the thing or character, see it’s importance in the native and derive their own sense of importance from that association.
I’m no psychologist but I have noticed the pattern with every show we watch.
