Bacon burger turbo, large chilli cheese fries and a... health quake salad shake?

Not his, Sam's.

Always the healthy type.

So why was Sam ordering a cheese burger with extra bacon and a fried egg on top just like his? That wasn't like him at all. In fact, Sam wasn't... Sam at all today. First, it was the random request of wanting to drive Baby, the Impala. Then, it was turning up the volume when one of Dean's songs played. Saying he had an 'awesome day' after hunting a random D-list ghost? Sam didn't really do 'awesome days'. And now he was drinking. ACTUALLY drinking with his brother. The list goes on.

"Who are you and what've you done with Sam?"

He asked bluntly with a sarcastic undertone. Sitting in a local bar, waiting for those juicy burgers to arrive. Leaning forward, elbows on the table as he stared his 'brother' in the eyes. You looked like Sam, sounded like Sam, but you didn't act like him at all. Because you weren't Sam.

You'd stumbled across a book. A not very good book. A black magic book. For witches, of course. And maybe used it to cast a spell to swap you and Sam's bodies.

But he didn't know that. All he knew was that his brother was acting odd today.

"An 'awesome' day, really?"
