Imagination

You have a LotR Sue to kill. Do you:

a) shoot her with a non-canonical weapon as it is the quickest and easiest method of dispatch,

or

b) strangle her with her own 'gleaming strands' of hair which she spent so long talking about in-fic, and then leave her for the Wargs, seeing as she claimed to have been raised by wolves?

If you picked b), congratulations, you have an imagination.

Imagination is closely related to creativity.
