After we ate we went back to the motel. We went to Dad's room because it was too early to go to sleep and we were bored. We sat on the bed while dad was doing a research on his computer. Lane wanted to help but dad didn't allow.
'I found something.' He finally said and we looked at him. 'The wife of the victim died eight months ago. It was a suicide, but the police suspected the husband even though they didn't find any evidence proving that he's involved. And apparently the wife was cheating on him.'
'He found out and killed her, and now she seeks revenge?' Dean suggested.
'It's possible. Take a look at this article.' We all gathered around Dad.
I heard a strange sound and a man appeared next to me. I screamed and hit him with a bottle that was on the table. The glass shattered but his face expressed only confusion.
'Cas, stop popping out of nowhere! Are you allergic to knocking?' Dean shouted.
'I'm not allergic to anything.' The stranger, whose name apparently was Cas, said.
Dean just shook his head and started gathering the big pieces of glass from the floor.
'Um, do you know him?' Lane asked.
'Yes. This is Castiel. He's our friend. Cas, those are Lane and Megan, my kids, and their friend Ryan.'
'Hello.' Castiel said.
'You just teleported here! When do we learn to do that?' Ryan got very excited.
'I don't teleport, I fly. I'm an angel.'
'Really? Cool!' It was Ryan again.
'And you can't learn to do this, only they can.' Castiel pointed at me and Lane.
'What?' Now I was very confused.
'Ah, why don't you three go to the diner and buy yourselves a drink?' Dad tried smiling and we left.

Sam's POV

'Cas, what the hell?' Dean said. 'You could've called. You scared the hell out of them.'
'I'm sorry. But we need to talk.'
'About what?' I asked. 'And what did you mean when you said that Lane and Megan can learn to fly.'
'That's what I'm here to talk about.' Cas looked at me. 'Lane and Megan are nephilims.'
'What? How?' Dean asked.
'Michelle is an angel?'
'No she was half angel and half demon.' Cas explained.
'Was?' Dean said.
'She was killed eleven years ago.'
I rubbed my forehead. It was too much. Michelle was dead? And she was part angel?
'I never noticed. Michelle wasn't acting like an angel or a demon when I was with her.'
'That's because she never discovered her powers. She grew up in an orphanage and never knew her parents. She had no reason to think that she was different.'
'And how do you know so much about her?' Dean wanted to know.
'One of our angels was watching her and was reporting what she was doing every day.'
'Do you know which angel was Michelle's… parent?' I wasn't sure if I should say mother or father.
'We don't know. The angel who was told about the child can't remember the name or appearance of the parent. We think that a spell was made so that the angel forgot completely about him or her.'
'And you never told us about them?' I shouted.
'I didn't know. I learned a week ago. And until now I was busy convincing almost everyone in Heaven that those kids are not a threat for the universe.'
'A treat? How can they be a treat?' I didn't understand.
'They're half angel and half demon. Plus they have Winchester blood in their veins. That makes them the most powerful creatures, right after God and Amara.'
Dean and I looked at each other and then at Cas.
'Wow.' Was the only thing Dean said.

Megan's POV

We went to the diner. We got ourselves cocoa and sat on a table.
'That was weird.' Ryan concluded.
'This Castiel scared the hell out of me.' I said.
'He felt nothing when you hit him. That was amazing.' Lane laughed.
'I like the trench coat. Maybe he'll be cool.' I said.
'What was he talking about? I mean the flying. He said that I can't but you can learn?' Ryan was curious.
'He probably meant that he'll teach us but not you because you're not related to us.' Lane suggested.
'What if he meant that you're angels too?' Ryan thought.
'Don't be stupid!' I threw the plastic fork that was on a table at him. 'We can't be. And last time I checked I had no wings on my back.'
We all laughed but suddenly Lane lowered his voice. 'Why there are so many people here?' He whispered.
Ryan and I looked around. Lane was right. There were more than twenty people around us. In a diner at the end of a small city. And they all were looking at us. The staff included. Suddenly they all flashed their black eyes.
I screamed and the three of us ran for the door. But it closed right before us. They threw Ryan across the room. I was still screaming when the demons pinned us on the wall. I couldn't move.
'The king wants to speak with you.' One of the demons said.
I heard banging on the door. 'Lane! Megan! Ryan!' Dean and dad yelled.
Lane squeezed my hand. The demon was about to grab us. I closed my eyes. I heard a strange noise and suddenly we were free and fell on the ground. When I opened my eyes, all the people were on the floor and there was black smoke all over the ceiling. It soon vanished. Dad broke the door and he and Dean came to us.
'Are you OK? What happened?' Dad looked worried.
'We're fine. Check on Ryan.' Lane pointed the corner where Ryan was thrown and Dean went.
'What happened?' Dad repeated.
'All those people were possessed by demons. Then they were gone. I don't know what happened.' I said and got up.
'One of the demons said 'The king wants to speak to you'. I think.' Lane added.
'Damn it, Crowley.' Dad said and helped Lane to get up.
Before I could ask who Crowley is, Dean and Ryan came to us. Ryan had blood on his face.
'Are you OK?' I went to see him.
'Don't worry. He'll live.' Dean said.
'I saw everything!' Ryan was very excited. 'You both closed your eyes but I saw it. There was yellow light all around you! And then the demons screamed and smoked out.'
Dean and Dad looked at each other and then at us. I had no idea what was happening.
