Levi never wanted to get involved. He thought this Eden's Gate stuff would fade eventually, or someone else would fix it. He wasn't a fighter anyways; hurting and/or killing people unerved him. He was content with hiding out till it was over. That was until he accidentally killed this Deputy fellow; the guy getting rid of his problem. Thanks to guilt and being irrational, he went and ahead took their identity. Maybe if he wanted something gone, he should do it himself. Now he finds himself with a whole range of new problems that he's gotta figure out; preferably without getting bloody.
