There's nothing I can really add to Rultaos' very helpful explanation, anything I can think of will actually be covered in the IC.

I will note that your characters shadow isn't a repressed emotion or something that he doesn't want anyone to see, rather it's your greatest desire. You can be as flamboyant about that desire as you like, everyone could know it's what you want. But the Shadow will show your character to just what extent you're actually willing to go for it by subverting and perverting it until it's nearly unrecognizable.
