"Hey" Dean greeted Sam with a smile who was sitting at the floor of Bobby's house and looking at the stars. "Hey, why are you up?" Sam asked. "Couldn't sleep" Dean said and sat beside his little brother. "So... this castiel" Dean started. "Yeah" Sam said. "Can he be trusted?" Dean asked. "Yeah, I know him. He can be trusted" Sam said. "So why do you think angels are here?" Dean asked. "There must be a bigger picture because angels are prohibited to walk the earth" sam said. "So let's ask him" Dean said and sam nodded. "Hey, castiel, we have some questions, so if you have a minute..." Sam strailed off and there was a flutter of wings and Castiel was there. "Hey Cas" Sam smiled. "Hello Dean, Sam" Castiel nodded. "Why did you call me?" Castiel asked. "It's better we step outside the house. Bobby's asleep" Sam said and the three stepped out of the house. "So, Cas, I am happy to see you on earth, but as far as I know angels are prohibited to walk the earth. So why exactly are you here?" Sam asked. "You're right. Angels are prohibited to walk the earth, we are here because of the seal business" Castiel said. "What exactly is this seal business?" Dean asked. "Think of these seals as locks on a door" Castiel said. "Okay, last one opens and?" Dean asked. "Lucifer walks free" castiel said.
Both the brothers were shocked to hear what castiel just said. "Lucifer? The devil?" Sam asked, shocked. Castiel nodded. Sam stumbled a little when Dean caught him. "Hey, you okay?" Dean asked. Sam nodded. "Yeah, just got a little dizzy" Sam said. "So who is breaking these seals?" Sam asked. "Lillith" castiel said and both the brothers had a look of anger on their faces. "I am gonna kill her" Sam growled. "Hey, take it easy, we are gonna stop her" Dean said. "Yes, Sam, we will stop her. You have to stay calm" castiel said. "STAY CALM? HOW THE HELL AM I SUPPOSED TO STAY CALM. FIRST SHE DRAGGED MY BROTHER TO HELL AND NOW SHE IS TRYING TO RELEASE THE DEVIL. HOW THE HELL AM I SUPPOSED TO STAY CALM" Sam panted heavily and his eyes were sparkling red with fury right now. Dean was stepping forward when castiel stopped him. "He is very angry at the moment. He can hurt you by his powers. See his eyes, he can cause destruction right now" Castiel whispered and stepped forward. "Sam, listen to me. You have to control your anger or else this place will be destroyed" castiel said and Sam looked at him and now his eyes were back to normal. "Sam, you are the most powerful human on this planet right now. You can either do good with your powers or really bad can happen. So, Sam I am gonna ask you to stay calm and focus to control your powers otherwise it can kill you" castiel said. "Sam, this is not up for discussion. You matter to me the most, I am not gonna lose you. We will defeat Lillith but I can't do it without you, little brother" Dean said and Sam nodded. "Alright, yeah okay. I am sorry but I don't know how to control my powers" Sam said. "I will help you Sam, you are our best shot at stopping this apocalypse train" castiel said and Sam nodded. They were in for a big journey and Sam was determined to stop this apocalypse train.
