User blog comment:Blur the Hedgehog/Shadow vs Metal Sonic/@comment-3162983-20110806140849/@comment-3418848-20110806203028

Yeah, but that's Metal's thing... he always tries to be the real Sonic because he hates Eggman for basing him off of Sonic. He doesn't like the idea of being a copy. He just wants to be his own person. It's easier to understand if you see his life story.

It's saying that Shadow just complains about Maria all day. He loved her like a sister and she died almost before his eyes trying to protect him.
