ACT THREE – THE RETURN

Castiel met the Elders again as he came to the Heavens. He bowed slightly. "I've heard that Dean had learned his lesson by now. Can you confirm that?" he asked curiously and looked at the only female Elder, Sandra.

"Yeah, we can," Sandra said and put a hand on his chest. "We listened to the conversation between Dean and Chris and Dean confirmed it himself. He'll listen closely from now on.

"Right. So he knows the difference between good and evil? Though he knew before but witches are a different matter."

"He does, believe us, please." Sandra looked at the other Elders who nodded and then back at Castiel. "So when does the exchange happen?"

"Tonight. If you help me," Castiel said smiling. "All four of them are sleeping. So we can do it easily."

The angel from the past and the Elders of the future changed the consciousness of Wyatt and Dean back into their right bodies—where they belonged.

PAST, 2007 – HOTEL ROOM

Dean jerked awake all of a sudden and looked confused around. He sighed in relief by realizing he was back in the past. Next to his bed laid his baby brother Sammy, yet still his mind was on Chris. He was impressed by the witch!

"Hey, you okay?" came Sam's voice tiredly. "Is it you, Dean, again?"

"Yeah, Sammy, it's me. Sleep on. I just need to think."

Sam just nodded and turned around again, yet Wyatt had brought up some interesting views. He also needed time to think about them.

There was a familiar noise in the room and both brothers sat immediately up. It was Castiel who just smiled at them. "I see that the Halliwells got you both thinking. That's interesting. So what did you learn then?"

"Let me speak first, please, Dean," Sam pleaded and his brother accepted quickly. He turned to the angel. "Wyatt showed me that we can also speak with ghosts, finding their reason for being held on Earth and then only kill one person. And not all. The others then can find their way to the Heavens or wherever they go to."

Castiel nodded. "Quite good. Dean?"

The man sighed. Looking up, Dean explained, "After Chris told me about his brother, me, and his powers, I needed some time to think. Meanwhile Chris was kidnapped and I had to test out these powers and find the triggers. Not easy, I can tell you. Never mind, I also found their special bond and casted my first spell which worked to my surprise.

"Anything else?"

"Yeah, I realized that good witches do exist. They also have a Book of Shadows and many spells, yet differ in another way like we do. Chris told me to still be careful, no matter what. Anyway, if we, in the future, find good witches and no bad news in rumors, we'll let them do their work." Dean turned to Castiel. "Believe me, I've learned my lesson. For sure."

Sam looked at him astonished. "You really have and so have I." He turned to Castiel. "I think you should go and see what Wyatt and his brother are doing. If they're okay—for good."

Castiel accepted this and vanished from view. It seemed that all had gone as planned, yet only the future will show this. It could be interesting to observe again.

Dean turned to him suddenly. "When Chris was kidnapped for revenge, I was afraid for him—just like for you. Wyatt would have killed me if his brother were dead. I was just glad that I could save him and that we could kill these demons. More than happy I was when I could hear him as well. It was strange but a good experience."

"I'm just glad you okay," Sam offered smiling. "As we encountered the ghosts, Wyatt showed me that talking can help as well. Finding the history of the family and the house, he quickly convinced me to only kill the person responsible and let the others go. It worked like a charme."

Dean laughed. "You know Chris told me that they both were born from Charmed power. Really funny." He looked at his brother directly. "Chris reminded me a lot of you. Smart, sarcastic and even more neurotic."

Now Sam laughed. "Yeah, Wyatt confirmed me this. Chris and I are a lot alike. Yeah, I've been told."

"So what's our next order? Have you looked for anything again?" Dean requested curiously.

Sam shook his head. "Nope, I had a lot in mind. But I'll start tomorrow in the morning if you agree."

"Sure, sure. Now let's sleep again. I'm tired." Dean laid down and closed his eyes in the end. It was good.

Sam smiled as he finally fell asleep. Life was good for once.

IN THE FUTURE

Wyatt and Chris had nearly reached their destination as Castiel appeared in front of them. Both turned around but said nothing and only shrugged. "Nice welcoming here, I see," the angel greeted them smiling.

The Halliwell brothers looked at him not happily. "Castiel, what are you doing here?" Wyatt asked confused. "Is everything okay back in the past?"

"It is. Dean has learned his lesson quite well," Castiel explained smiling and turned to Chris. "Whatever you did and told him made Dean change his mind. Care to share with the folks? How long have you known that it wasn't your brother?"

"From the start," Chris said and turned to his older brother grinning. "As if you didn't know your own powers. Dean was very confused to begin with. Still, I was impressed that he managed your powers and found the triggers, even for healing."

"Yup, he was immensely proud of that fact," Castiel offered grinning as well. "Anyway, what else have you told him, Chris?"

Chris only shrugged his shoulders. "Nothing much. Only not to think in two straight categories. There's not black and white only but also very many steps of gray. Yet he should still be careful. Bad witches do exist in our universe as well."

"Yeah, known as warlocks," Wyatt added.

"Okay, though I'm not in need to understand your universe," Castiel explained in a calm tone. "Anyway, thank you for your help and I hope you made my job a bit easier in the past."

Chris and Wyatt looked at each other baffled. "Easier?" they asked at once. "How can we understand this? It's not fair."

Castiel shook his head amused. "Creepy, when you both speak as one. Never mind, again thank you but I need to go now!" He slowly vanished from view.

After he was gone—for good, the younger man turned to his big brother perplexed. "He was a very strange angel, not the like the ones we know but you can tell me now what you really did."

Wyatt rolled his eyes. "Nothing much what I already told you. We only were hunting ghosts but we only killed one as he was responsible for trapping the others. It was not easy."

"Why not easy? Ghosts are daily business for us as we summon them usually, dumb ass. So what was your problem?" Chris asked with his hands in the air. "I really had the easier job here."

"Again nothing, Chris," Wyatt repeated with knocking on his brother's head. "It was easy for me but not for Sam, Dean's brother. Yet he was fond of this way of dealing with ghosts."

Chris rubbed his eyes warily and yawned all of a sudden. "I'm still tired. Being kidnapped was not on my list for today, though it were demons from my past life. So not fun!"

"Be glad that Dean could save and heal you in the end." Wyatt hugged his baby brother tightly. "For one second I thought I'd lose you. I'm just happy to be back and have you back in my life."

"Thanks. But now I'm going to bed."

"Yeah, okay. Have a good sleep! I'll be watching over you."

The older brother did as promised but was glad to be home again. For once, he was happy to meet his whole family, cousins included. Though he had the feeling that they were called home for a certain purpose. Maybe the brothers should return home—for good. Their parents were not happy when their sons had moved out and so far away. Sighing, he watched over his brother's sleep until sleep called himself. Tomorrow they would be in San Francisco.

CASTIEL & THE ELDERS, AGAIN

The angel of the past was once again called back to the Elders but to his surprise, only Sandra was there. "What's going on? Why did you call me here, Sandra? I've got things to do," Castiel said and crossed his arms over the chest.

"You're like a child right now," Sandra replied smiling. "Never mind. We wanted to thank you for your little idea with switching the older brothers. So, once more thank you."

"You don't have to thank me. Dean needed his lesson and your Chris seemed to be a good teacher. He learned it for good, I think." Castiel smiled as well.

"Chris will be and Wyatt has learned as well, it seemed," Sandra agreed nodding. "You can go to your own time now. We'll look over these two Halliwell brothers."

"Yeah, and I will over the Winchester ones. Not easy, I can assure you." Castiel greeted with his fingers and vanished finally from view.

Sandra took a deep breath and looked down on Earth, especially on the Halliwells.

TBC ...

Hope that satisfies your expectations and there will be some action for sure. With the other chapters it might be goody, goody and too easy but please, be kind. As said above: first crossover!

Let me know what you think!
