As a lie, there are many things I'm afraid of.
Being found out, for instance. When someone realises you're just a lie, not exactly there, the mask you display - a happy shell of false talent in a bid to draw talent. As the saying goes, glass sparkles more than diamond because it has much more to prove.
Lies have everything to prove and nothing to show.
Another fear of being a lie is meeting the truth. You know what I mean. Them people who are really good. Not really good, really good. They know what they do, and they do what they do, and that be the truth, for the truth need not shine; and a well used sword is often dull and scratched - yet these markings are but proof of its ability.
A lie has no scratches or markings for a single one who certainly shatter its glass facade.
Then there is the opposite of the lie, the hidden truth. A lie's greatest fear and one all lies seek to quash. Hidden talent, humble worksmiths, great but reclusive geniuses, all of them the lies seek to destroy - for they are the antithesis of their very philosophy and existance. To a lie, hidden truths are like the mold that grows underneath the wallpaper - ignored unless the risk of them being seen by visitors is too great. And then the lies move in swift and deadly, to remove the talent lest it threatens the lie's hard earned position of pseudo-talent.
But once in a while, a piece of truth leaks out. As it goes, the truth will out, and mold tends to grow everywhere, no matter how much plant-killer you use. And when that happens, all the glass lie can do is hide its mask in shame, as the hidden talents and true truths grow beyond its ability to overshadow, and its light no longer attributed to any inner fire of its own.
The moon was thought a mystical object till scientists realised it merely reflected the light from the sun.
As a lie, I am capable of weaving words. Painting pictures that aren't there. Hiding in shadows so dark they can't be seen at all.
Yet even amongst lies, there is talent. The talent of deception, of charisma, of making glass look like diamonds, and confidence in all things false.
So what about a lie of a lie? What talents does he have?
Since when did a doppelganger need to impersonate itself?
