"Just think of it, Sam. All the tender loving care Dean gave me made me what I am today." The happy grateful tone of her voice made Sam's skin crawl. I love how vividly you describe Dean's revulsion at having to hurt others, his weariness and desire to stop hurting, to end his torture and stop hurting and his fear that he wouldn't do a good job and Alastair would put him back on the wrack. It was exquisite and raw. I felt it as I read. Sam's understanding of Dean's guilt, and his explanation as to why he would never cover the scars was fantastic! He turned something bad into a positive, decided to wear it like a badge. both brother's did things that they regret. Both have been forced by circumstances to be people they didn't want to be and do things they didn't want to do. I'm glad he was able to make Dean see that by destroying the bond between them was exactly what the demons wanted.
The happy, grateful tone of her voice made Sam's skin crawl.
I'm glad you liked the story. If demons ever did try something like this I know they'd fail. I believe Sam would forgive Dean much quicker than Dean would forgive himself. Killing himself and ending right back in hell sounded like a plan to Dean.
Thanks for reading and reviewing, I appreciate it!
