Dean, Sam and Donatello are arguing about if Jack is good or not. Dean wants to find a way to kill him since Jack is Lucifers son. But since you are also Lucifers child you were hurt. You and Jack were half siblings, ofcourse it hurt when a loved one wants to kill your half-brother. "Okay, that's it I'm done, alright. Cause he's not God, he's not Cass, he's not Simba. He's the frigging devil!" Dean said pointing to Jack who was supposed to be on the couch but was gone.
