Death Note 'L' fans, take some time to read this interesting article:
It may seem that L has Asperger's Syndrome.
His parents might have left him after noticing his autistic traits. (But it makes him so special!) Hmm. That's just my opinion since his background wasn't stated anywhere. We only know that Watari brought him into Wammy's house.
I just love the way the Authors wrote the whole story.
But we still love him, don't we?
