A slim shady
The Slim Shady in YOU is the dark, evil part of you. The Eminem in YOU is the good, sane part of you.
He texted me: 'The dark part of you is Slim Shady, the good part is Em.'
He said, 'Your dark side is Slim Shady, your good side is Eminem.'
He told me, 'The evil part of you is Slim Shady, the good part is Em.'
