Hey! So this is just an idea that has been dancing around in my head ;) Things you should know about this:

-It's not set during any particular time of things happening in the show

-And there are many characters that died in the show, but they are still alive in this fic :)

-Castiel and Gabriel are both full angels!

Coming: Destiel and maybe, just maybe, Sabriel ;)

Two weeks till the wedding:

"Gabriel." Castiel called quietly. "Could you come here, please?"

"What's up Cassie?" Gabriel smirked from the couch. Castiel threw something to Gabriel.

"You see what that is?" Castiel asked quietly. Dean and Sam went to visit Bobby, so they asked Castiel and Gabriel to stay and keep an eye on everything.

"Hex bag. Powerful." Gabriel said and burned it immediately.

"And who...-" Castiel started to ask when Gabriel interrupted.

"Witches." Gabriel said. "I'll try to find that bitch; you stay here and DON'T TELL Dean-O and Samsquatch." Gabriel disappeared and Cas was alone.

Castiel was happy. He and Dean were together and everything was fine. But that hex bag had brought another dark cloud on top of their heads. Someone is trying to kill Dean or Sam. He didn't want to lose them. And he knew that Gabriel had been looking for his mate since humans were created. And when Gabriel had left heaven, he said that he was going to find his mate. And now finally Gabriel found Sam. Just like Castiel had found Dean. He had to leave, he had to help Gabriel. In a flutter of wings, Cas was gone.

"Cas?" Dean asked as he walked into the motel room. Dean walked into Sam's room and he found his brother, who looked like a lost puppy.

"They've left." Sam said sadly. Dean wondered where their angels had gone.

"They'll be here soon." Dean said "I'll call Cas." Dean walked back to his room and waited for Cas to answer.

Dean: Hey babe? Where are you?

Cas: Umm... I'm with Gabriel.

Dean: Yeah, but where are you?

Cas: I'm not going to lie to him (said to Gabriel)

Dean: Cas? What are you not going to lie about?

Cas: We found a hex bag in your room! We found the witch.

Dean: Awesome! But you two... hunting? You should have asked me and Sammy to help.

Cas: I didn't want you anywhere near her.

Dean: Bullshit. Who is she?

Cas: *coughs* Memebiah.

Dean: That bitch is also a witch? Come back. I don't want you anywhere near her either.

Cas: Come on Dean! I'm an angel of lord, I can handle one witch. And I have Gabriel to help.

Dean: That is not the reason...

Cas: You're still mad at me because of that? Dean let's talk when I come back okay?

Dean: There is nothing to talk about.

Cas: Bye.

Dean threw his phone onto his bed. He turned the TV on and saw that his favourite show was on.

From: Dean

They r huntin a witch. They'll be back soon.

To: Sam

Dean sent the text to Sam. He waited for a second until Sam answered.

From: Sam

K

To: Dean

Soon there was flutter of wings, and Dean saw two bloody angels, lying on the floor.

"What the...-" Dean started "SAM! SAMMY!"

Sam ran there quickly."Oh my... Gabe? Gabe?" Sam kneeled next to his boyfriend.

"Cas? Hey, what the hell happened in there?" Dean carried Cas to his bed. Blood was dripping from his eye. It looked like he was crying blood.

"Dean, It was a trap! There were 7 witches, waiting for us, then they started mumbling something and Cas started bleeding and I tried everything and I started bleeding and then I snapped us out of there." Gabriel started talking when Cas didn't say a thing.

"We should have come with you." Sam said as he hugged Gabriel tightly.

"NO!" Gabriel growled as he wiped blood from his face. "You both would be dead now! And this affected Cassie more, because he told her that he is an angel of lord!"

"Cas told her? You mean Memebiah?" Dean turned away from Cas. Gabriel nodded and stood up.

"Is there any chocolate in here?" Gabriel asked and Sam gave him his snickers. "Since when have you carried chocolate all over the place?"

"Since the day we started dating." Sam said and blushed slightly.

"How do you know that Cas told her?" Dean asked and watched Sam oddly.

"Cas told me as we went there. It was that time we got drunk, remember?" Gabriel smirked as he ate his snickers.

"How could I forget?" Dean growled. He was still pretty mad because of that.

Cas started moving and whined a bit. Dean turned back to Cas and looked worried.

"Cas are you okay? What happened?" Dean asked even though Gabriel had just told him.

"Dean it was a trap." Castiel said and started wiping blood from his face.

"I know. We must talk about it." Dean said. He hated that he had to talk with Castiel about his emotions and stuff. But Dean was pretty sure that he had to break up with Castiel. Dean just couldn't trust him anymore.

Gabriel and Sam left the room in silence.

"I can't trust you anymore. Every time you're not with me, I just keep thinking that you're with someone else. I wanted to be the one who makes you happy, makes you smile. But when you cheated on me, it broke me. I'm used to everything. People leave me all the time and I just keep fighting. But what you did, it was a lot worse than anything I've ever experienced. I trusted you and you just... I can't do this anymore, I can't keep pretending." Dean sighed as the tears floated down his face.

"You don't love me anymore?" Cas asked as he tilted his head. He started feeling things again.

"I do, love you. More than anything, but..." Dean started as he wiped his tears away from his cheeks.

"And I'm not the one who slept with someone. It was you. You slept with Memebiah. I only kissed her." Cas said and stared at Dean. "And I was meaning to speak with you tonight." Dean puckered his eyebrows.

"Why?" Dean asked and stared as Cas stood up. His eyes expanded when Cas got down on one knee. Cas took something from his pocket. It was a velvet box.

"Dean, I love you and I always have. And I always will. I was going to ask if you would want to get married." Cas explained. Dean was in shock.

Tears floated down Dean's cheeks again. "I'm sorry, Cas. I can't." And with that, Dean ran away. Out from the room and straight to the Impala and he decided to spend the night driving around the town. It's not like he could sleep anymore.

Dun dun duuun! Yeah, this is complicated, but EVERYTHING will be explained in the next chapter. And remember my lovely beta-reader, more-profound-bond.
