Oh yeah...the other brother
Ok an idea for an episode ending I came up with when talking to my friend. So Sam and Dean finish a case. As they are leaving the motel room they open the door and...Adam (mind him?) is on the other side. He has his back to them and when they say his name, he slowly turns around, looks at them with a smirk on his face and says "Hello 'brothers' remember me" Then the screen goes to black and credits roll.
