TM7 tag. Envy was taunting Sam.  I know things.  Sam looked up and saw fear in Dean’s eyes.  Not from the danger of facing the seven deadly sins personified.  No.., Dean feared something else, something more.  Sam shook at the realization.  Dean feared the truth. 

He felt like he was betraying Dean by allowing this monster to defile his good name and all the great accomplishments of his life, and a part of him wanted to bust the demon’s jaw himself for daring to speak Dean’s name.  But a part of him needed to know and Dean wasn’t talking.  It was sordid and unsavory and so very wrong on so many levels… but God help him, he needed to know.
