When Grey attended Lockwood high, he met Ney.
Just because one never likes to talk, or listen, does not mean they're heartless.
Grey knew that although Ney was cold towards others he was kind.
He talked, only to people who he trusts.
He listens, he just doesn't like to look like he is.
And he has those huge headphones because noise just sucks.
He wasn't bad... He was awesome. Grey fell for that.
