DOCTOR: I'm not a hero.

ROBIN: Well neither am I. But if we both keep pretending to be, perhaps others will be heroes in our name. - Robot of Sherwood

Ultimately the moral of the story is very simple, never meet your heroes! Because your heroes never match up to the legend you created. Or in this case, your hero is someone that you created yourself and was never real at all!

But it also is a story about independence. 

Sure, fictional heroes that inspired you as a child to be who you are now may not be real, but that doesn't matter. Sure, J.K. Rowling may actually be an awful person, but don't let that ruin what Harry Potter meant to you. The point of heroes isn't to bend space and time to fangirl over how great they are, the point of heroes are that they inspire you to be great. And maybe, just maybe, by the very action of being great, you'll inspire someone else to be great after you.

And that's exactly what Charley did.
