In the morning, Dean's eyes open after his nightmare about Mary. He and Sam both wake up on the cabin floor in the nursery, the replay for last night's replay in the brothers mind. Wait, what was that? Dean was about to ask before Sam cut him off. Lucifer's son and Michael's daughter. As both of the hunters got up from the floor. Dean then grabs his gun as they both exit the cabin together.
Can they teleport? Dean shouted at Sam as he turned around to face him. Huh? Sam replied back as he wondered what Dean was talking about since this is the first time that a Nephilim and a Nephalem have been born. The kids. Do they have wings? Dean asked, he wasn't thinking about anything except killing the cousins, as he viewed them both as a threat considering who both of their father's are.
I don't know. Sam replied, clearly lost in thought as the two look around the empty cabin yard. Not a single trace of the two offsprings of Lucifer and Michael was around.
