Abaddon gains an advantage over Crowley by kidnapping his son Gavin MacLeod, and uses it to turn him against the Winchesters. On the other side, Castiel learns more about Metatron's plan.
- Eye Scream: Abaddon plays on Crowley's paternal protectiveness by melting Gavin's eyes out of his skull. Luckily it's reversible.
- Fish Out of Temporal Water: Gavin McLeod, son of Crowley.
- Killed Off for Real: Abaddon and Malachi.
- No Sell: The first blade makes Dean immune to Abaddon's telekinesis.
- Oh Crap: Abaddon's smug smile slips off fast when she sees Dean juiced-up on the Mark of Cain and the First Blade becoming immune to her demonic powers.
- Papa Wolf: The newly found humanity in Crowley makes him more concerned for his son...which pisses him off.
- Perp Sweating: Interrogating Ezra, Dean seems ready to just start cutting, but then he and Sam play on his insecurities by talking about what a loser he is.
- Suicidal Overconfidence: Part of what finally brings Abaddon down. Despite being a former lover of Cain himself, she didn't appreciate what the blade and the mark could do.
