Editor's Note: In this week's Fan Video article, LK goes far beyond finding videos that interpret an episode's theme. She has done extensive biblical research and shares with us her insights on the Mark of Cain's plot line. She also tackles the confusing canon issues on whether the Mark was shared or given to Dean, the lock and key idea, Lucifer's role in the Mark and much more. Given that, I've made this a Let's Discuss article, so you can freely discuss your questions, confusion and theories. I also highly recommend the thirdvideo that is linked at the very end of the article. LK was too modest to showcase it, but it is her own creation about the MoC...and it is outstanding. - Nightsky
aka Cain and Abel, story about two brothers, foreshadowing and the MOC
"8 Now Cain said to his brother Abel, “Let’s go out to the field.”While they were in the field, Cain attacked his brother Abel and killed him.
9 Then the Lord said to Cain, “Where is your brother Abel?”
“I don’t know,” he replied. “Am I my brother’s keeper?”
10 The Lord said, “What have you done? Listen! Your brother’s blood cries out to me from the ground."
- Genesis 4:8-10, New International Version (NIV)
