"I hate it when this happens," Dean complained, "Seriously, why does this happen to us so much?! A second time!" Sam looked at his brother with annoyance and didn't comment on anything.

You, Cas and the Winchesters were zapped into the real world once again, just like when Balthazar had done it years ago... but this time it was different. You didn't take place of the actors in the other dimension, you were just added to this other world. The real Jensen, Jared and Misha are walking around right now as well.

You snapped out of your thoughts and looked at the boys with alarm. "We cannot be caught by our counterparts. It could cause something bad to happen," You warned, "Something related to time and space."

Sam looked at each one of you one by one with concern. "Alright, everyone split up and try to find something to get back. Don't get caught. If any issues, call," The younger Winchester instructed and you all nodded, choosing a path to follow.

You walked ahead, completely alert and frightened at the fact that you didn't want to see the 'you' of this dimension. You looked ahead, then turned-

"Hey Nina!" A voice called out and you looked at the source sharply.

It was Cas... but it wasn't him exactly.

Oh no, it's that guy Misha, You thought with a look of horror on your face.

"Nina, I've been looking all over for you. They'll be shooting soon and we need to prepare," Misha told and you looked at him with slight confusion, not used to being called 'Nina', your name is Spencer.

Must be the actress' name who plays me on the show, You thought.

"Okay... Misha," You said, slightly flinching at saying his name. You didn't want him to be suspicious of you so you smiled at him.

*****

Sam and Dean hear voices up ahead, around the trailer's corner.

"I just got a call from Danneel. She said she got the package," Jensen told Jared and his friend smiled. "Oh that's great! I hope it turns out good," Jared commented.

Dean looked at his brother, "I've got an idea. Follow my lead." Sam looked with confusion but listened to his brother, asking no questions.

Dean sneaked upon the unsuspecting Jensen Ackles and hit him on the head with the back of his gun. Jensen stumbled and fell to the floor, unconscious. Sam was alarmed but quickly did the same thing to Jared.

"Okay now what?!" Sam questioned anxiously. "Well," Dean chuckled, "I didn't think we'd reach till this point and-"

Sam rolled his eyes and wrapped Jared's arm across his shoulder, pulling him behind the trailer. Dean did the same and the brothers decided to put the two unconscious actors in one of the trailers.

They dust their hands in a job accomplished then walk out, closing the door tightly behind them. "Where's Cas?" Dean asked and Sam shrugged. "Where's Spencer?" Dam questioned and the brothers huffed.

*****

"And ACTION!"

"Listen Spencer, it's not safe for you to go on this hunt. I do not want you hurt," Castiel stepped towards you and sighed, "You mean a lot to me."

You shivered slightly. It felt so real all of a sudden, as if Castiel was actually saying it to you. You tilted your head slightly and looked at him deeply.

"Oh Cas... it'll be fine. You'll be watching over me right?" You said, coming out naturally even though you're not that much of an actress. "I'll always watch over you," Castiel moved closer and cupped your cheek. He bent down and placed his lips to yours.

You felt a bit shocked at first but then melted into the kiss, your mind constantly thinking of Misha as being Castiel. You wrapped your arms around Misha's neck and ran a hand through the hair on the back of his neck.

You felt an unscripted moan approaching but you held it in, not wanting to ruin the take.

Castiel watched closely, boiling with rage as he saw you act compassionately with this... imposter Angel Misha. He clenched his fists and glared at you.

You moved your head a bit, your eyes fluttering open for a moment and finding Castiel standing slightly away, behind all the crew.

You gasped slightly at the sight of Castiel. He was told to be hidden and not to be spotted but he stood there out in the open.

Misha pulled away. "What's wrong?" He asked with worry and you looked at him with embarrassment. "I... I'm sorry. I got distracted," You kept eyeing Castiel then sighed with relief s you watched him walk away.

Misha looked at you with a questioning look. "Alright, we got enough for the shot. Let's do the next scene. Richard!," The director announced and Misha moved away.

He started walking then turned back, "Hey, do you want to come to my trailer and practice the next scenes?" You looked at him hesitantly then nodded with a smile.

Misha led you to his place of relaxation on set and you got a bit comfortable, taking your jacket off. It was quite nice and cosy inside, you could get used to this life.

"Okay so the next scene involves Cas and Spencer really close and they have a conversation and all that," Misha explained and you nodded.

He sat beside you on the couch and scanned the paper he had infront of him. He shook his head then looked at you. "I think it's better if we stand up," He told and ran a hand through his hair.

You did as he said and he the you the script, saying that he knows all the lines and doesn't need it.

"Look Spencer, I care about you and I will not allow this. Sam and Dean can handle it," Misha delivered his dialogue. "But Cas, I can't just sit around and do nothing," You say, "I feel useless and weak. You can't protect me or tell me what to do and what not to do-"

You were pushed to the trailer wall behind you, you gasped slightly and looked at Misha, who held you down, with fright.

"Sorry, I should have warned you but that's how the scene goes. You should have known," He said and looked down. You bit your lip, hoping he wouldn't notice that you're not 'Nina'.

"You mean so much to me Spencer. How many times should I tell you before you understand?" Misha said, clearly saying his lines.

You didn't need to look at the paper, you replied with the way you would to the actual Cas. "I can already see it in you Cas. You don't need to tell me," You said and looked into his beautiful blue eyes.

He kissed you, this time harder than in the scene you had filmed earlier on. He was pressed against your body, hands on your hips while yours were snaked around his neck.

He pulled away after a few seconds and looked at you nervously. The scene goes like that but he made the kiss much more deeper, his slight crush on you being the culprit... well not you, but 'Nina'.

You looked at him, feeling unsatisfied, and pulled him towards you by his neck. You kissed the life out of him, causing him to groan slightly.

You slipped the trench coat he was wearing from his Castiel costume off his shoulders then the suit blazer. You wrapped your hand around his tie and tugged on it, pulling him closer.

You moaned but then a feeling of regret filled inside you.

You like Cas but you'll never go anywhere with him. Your relationship with him with be nothing more than friendship and it made you sad. You're willing with Misha because atleast you have a chance with him, he seems to not mind kissing you. You're not even sure if Cas knows what a kiss is.

"Cas..." You moaned and Misha paused, looking at you with confusion. You froze, realising your slip.

"I thought we finished practicing the scene when you decided to kiss me again," He said and you bit your lip. "Sorry, I uh... You still look a lot like Cas," You gestured to his clothes and he looked down at himself.

"Maybe I should take some more off so that you don't make that mistake-"

The door of the trailer swung wide after being forced open. You looked over Misha's shoulder to find Castiel standing there with anger and rage.

You kissed Misha, to distract him from the person who just entered but he pulled away and looked back, unable to remain calm.

"Wh-Who are you?!" He stuttered, scanning the copy of him with fascination and horror. Castiel walked ahead and placed his hand on Misha's head, knocking him out cold.

"Cas, what are you doing?! You can't be seen!" You whisper furiously as you grab his coat and tug it down. "How could you be so open with him? You are not the person he loves," Castiel argued and you looked at him with disbelief.

"This is what you came here for?!" You rolled your eyes, "Cas, I can do whatever I want and in some way, I am the person he likes... atleast I look like her."

You both quarelled further, about the scene that was shot before as well. You became frustrated quickly till you heard a low groan of pain.

You turned sharply to see Misha getting up and holding his head. He steadied himself and watched you standing infront of Castiel.

"W-What's going on?!" He questioned and moved closer, "Nina, get away from... him. He's some psycho trying to be me." Misha held your hand and pulled you closer to him.

"No," Castiel said flatly and held your other hand, bringing you to him instead. "Get away from her!" Misha yelled and wrapped his arm around your waist. Castiel looked at him with hate, and squinty eyes, and throws a punch to him.

Misha stumbled back as you gasped in shock. "CAS, What's wrong with you?!" You shouted and moved away. The two look-alikes fought against each other, stating how you are theirs, while the other argued back.

You huffed and stamped your foot on the floor. You look at the two 'children' then walk out of the trailer, irritated.

Castiel watched you leave and pushes Misha off, running after you. The actor is so flustered and detached that he starts questioning everything.

He decides to dial his friends phone numbers but none of them pick up. Not hearing from Jared and Jensen was quite suspicious as well.

Misha gathered his things and rushed out of the trailer, aiming to leave the set that had gotten quite creepy tonight.

Castiel finds you behind the trailer, sobbing with your head in your hands. He looked at you with sadness as he approached slowly. "Spencer..." He said softly but you glared at him.

"Don't... do that!" You exclaimed, "Do you know how happy I was with him? He's actually someone who likes me-"

"But it's not you-"

"Don't talk Castiel!" You raised a finger and he remained quiet, "He's probably the only chance I've got with someone who's similar to you. I really like you but you probably don't care about it. Misha was the only way I could be happy and now... and now he's probably become crazy with your appearing!"

Castiel stepped forward with his fists clenched tightly. "You are wrong," He said flatly, "I admire you so much and you can't even see that." He touches your forehead and you both are zapped to the trailer.

You feel a bit dizzy but it goes away after Castiel places his hands on your waist and grips then tightly. "I feel emotions when I think of you," He says huskily, "No one else makes me feel like that."

You used to think he wouldn't even know what a kiss is but oh how wrong you were.

He grabbed your arms and pushed you against the wall, gripping tightly and kissing your neck ferociously. Even though he was driven with lust... You felt a sense of anger and frustration in him.

"Cas..." You moaned, clutching his shirt, "We should... talk instead of... this." He stopped for a moment then continued, his hands moving downwards.

"Cas please-"

"Stop talking Spencer," He said authoritatively, "You make me feel things that I am normally incapable of feeling. This is what you get for it."

You looked at him with a slight smirk, completely turned on by the way he dominated you. You ran your fingers through his hair, pulling on it at times when you'd feel the pleasure echoing inside you.

A low groan escaped his mouth while you kissed him passionately. You took his two top layers off, leaving his dress shirt and tie on. "It's your turn," He said with a husky voice as he moved his hands under your shirt.

He pulled it over your head and stared at you in awe, a shiver running down his spine. You broke his daze by crashing your lips onto his once again, then pulling his tie off with one strong tug after opening it up.

He pushed you harder into the wall and picked you up by your thighs. You wrapped your legs around his torso, never breaking the kiss.

He took you to the couch and crawled on top of you. "Cas wait," You said, your hands on his chest, "So... You love me?" He looked at you for a moment then sighed, "If doing this doesn't say 'I love you' then I don't know what will."

You smiled slightly then moved your hands to his tensed shoulders, rubbing them slightly. "Stop being angry Cas. I love you too, no one can EVER replace you," You said softly and wrapped your arms around his neck and pulling him closer.

*****

You walk ahead to where you catch a glimpse of Sam and Dean. You wave to them and they look relieved to find you. This is the spot where you four had appeared into this other dimension.

"Wow you guys look..." Dean analysed you and Cas from top to bottom. You both tried your best to look 'normal' but your hair was still slightly frizzy and Castiel's clothing was wrinkled and not as perfect as they normally look.

"Nevermind us," Cas said, "Have you found a way to get back?" Sam looked at Dean then shook his head. All four of you sighed.

A sudden thought came into your mind.

"I didn't say goodbye to Misha..." You said softly and Castiel looked at you surprisingly with a warm look. He held your hand and squeezed it slightly.

"Well atleast-"

ZAP!

You were standing in the Men of Letters Bunker, the four of you completely startled and lost at the sudden change in place.

"Uh... we're back?" Dean questioned, looking around. "You sure?" Sam raised his eyebrows then the guys looked around.

Cas walked over to the machete that lay in its sheath on top of a shelf and took it out. He looked at it closely then cut his finger lightly with it.

You looked at him with alarm then walked over, holding his hand. "The blade is real so this isn't a television set," Castiel stated and you put a paper over his finger, not able to find tissue anywhere.

Sam and Dean smiled then got relaxed, walking to their rooms. Castiel looked at you, "I'll be fine Spencer. I'll heal."

You nodded then sighed, "I didn't get to say bye to Misha." He put his arm around your waist and kissed your head, "Well, you have me... and I'll never leave you." You looked up to him and pecked him on the lips.

You chuckled at a thought, "I wonder how Misha would react tomorrow when he sees the real Nina."
