Why this must be read: "The Possibility" is a fabulous crossover which uses the Mirage of Blaze mythology and characters to play with some very interesting themes and ideas in the Death Note 'verse. L is the focus of the story, and
labingi gives him a very innovative and intriguing backstory which is revealed slowly through some of the Mirage of Blaze characters - Chiaki in particular - and though I don't want to give away what that is, I will say it leads him to having more in common with Light than he would have thought. Additionally, this incarnation of Light is a beautifully human, even sympathetic one, who nonetheless is completely unrelenting in his devotion to his dream;
labingi writes him so we can see both why L is drawn to him and why he must be stopped.
My favorite element of this story is the convincing nature of the Light/L, often an incredibly difficult pairing to pull off, but it's also absolutely worth reading for the wonderful plot, the depth of the (highly in-character!) characters, and what it says about the human experience.
