There is a sequel post so there will be a sequel ^_^

His head hurt and there were odd humming sounds. Dean slowly opened his eyes. He couldnt even begin to remember how he got here, but it did seem like a familiar place. Not familiar as in a place he had been before, but a place he had been before. Dean slowly rose to his feet off of the metal grate he was laying on, and tried his hardest to remember why he was here or where he was in the first place. Dean continued to roam around the weird space he was in until he heard a creaking door open and he decided to bolt down the stairs he found on his left-hand side.

"Just wait here, Rose, he said. I'll be back, Rose, he said. Its been the entire war! Where in the universe could he be?" Dean recognized the voice a bit and suddenly memories flooded into his head. He remembered this place because he had seen it while watching tv with Charlie. Dean was utterly confused as to why he was in the TARDIS. He quickly sneaked up the stairs to meet this so-called 'Rose'.

"Um, hey, uh, I don't know how I got here so please dont freak out. I think I heard your name was Rose?" Dean introduced himself with. Rose looked freaked out for a moment, but came to the realization he probably knew less about why he was here than she did. It wasn't until Rose started to speak that she realized that this strange man who had wandered into the TARDIS had a rather large gash on his brow that most likely needed medical attention as soon as possible. Rose stepped forward to him and placed two fingers to his forehead. Dean winced at the contact and bright light, but immediately realized what she was doing, or rather, what she was. His mouth was gaping and he didn't know what to say next, but he thought he should probably start with his name.

"Uh, thanks for healing me, I guess. My name is Dean by the way."

"Yes, I know who you are. I think it is possible that we have met.," she replied with a sweet smile. "My friend, the Doctor, he kinda left me behind. I didn't really know where I was so I just kind of came back here. But that was a while ago. I've been by myself for a while now. I found you in here, and I guess that's where our stories merge. 'Fess up- how did you end up here?" Rose asked with her head slightly tilted to the side.

What did she mean, possible that we had met? She seemed familiar, but do I want to ask? Dean thought to himself. He brought himself back to the conversation with a smile.

"I woke up with a headache and, I don't know, you came in, I guess. What did you mean by 'possible that we had met? You seem familiar, and I cant figure out why."

"Dean, are you serious? Remember Rosie, your best friend as a child? Well, Rosie is all grown up now."

The realization was like a slap in the face with a frozen fish. How could he forget his own best friend? He felt shame in not remembering who Rose was, but had she indeed grown up.

"Sorry about the forgetting thing. Hey, can we talk outside? It feels a bit chilly in here."

Rose knew what he meant. She was always complaining to the Doctor about how cold it was in the console room. She nodded, but told Dean she had to grab her jacket first.

Dean ran out the doors of the TARDIS and quickly set up the ring of holy oil. He needed to know why he was miraculously healed by someone he had known practically his whole life, and why suddenly now he was realizing what she could be.

Rose stepped outside the doors and pulled on her jacket. She was already getting warmer and was ready to catch up with her old buddy.

"So, what are you, Rose?" Dean said with a seriously straight face, as if his emotions were on a whiteboard that had suddenly gotten cleared. Rose shifted her weight from one leg to the other nervously, but answered his open-ended question without skipping a beat.

"I don't know what you mean, Dean."

"What I mean is, how did you heal me? Maybe you're magical, maybe it was because you're not human," Dean said sternly while flicking a book of lit matches to their feet, igniting the oil laid out. Rose had a look of panic twinkling in the chocolate eyes of hers. "Maybe you've always been an angel. But the question remains, why would an angel be looking for the Doctor?" Dean continued.

"Th-there was a war. He and I… were separated. Look, I just want to find and be with the man I love. I'm sorry the TARDIS picked you up." Rose confessed. Dean looked slightly empathetic but still angry over the fact that his old 'bestie' was really an angel.

"Since when do angels fall in love?" Dean asked, prying as much information about his celestial friend standing in a ring of fire mere feet away from him. Rose's face softened up and a grin was starting to form on her face, no longer being upset about the trap he had set.

"Perhaps that's a question you ought to ask Castiel." Rose finally answered.

Dean felt a surge of emotion inside. He didn't know whether she was saying that Cas was in love with him or if she didn't know how to answer that question in the right manner. He was pretty sure it was the first one, though. Dean felt warmth in his cheeks and opened his eyes, not remembering closing them. He noticed that Rose was staring at him with a look that was warm but yet, he could feel it was simply a friendly expression.

"How… how do you know about Cas… and why would he know if you're in love with this Doctor guy?" Dean sheepishly asked. He could feel the anxiety as if it was pulling his stomach into a tight ball and not letting go. How could she know about his feelings for Castiel? He had never even told Cas or Sam let alone someone he hadn't seen in years.

"Oh, it's kind of obvious. See, angels can technically see your physical form, but it's easier for them to see a human's soul, and the soul reveals everything. No worries I won't tell anyone. Although, what I just told you about the souls, only some angels can. I don't know if your buddy Cas can see your true feelings. Maybe you should ask him yourself about angels falling in love," she told him. "I'll take you back to the motel room the TARDIS stole you from, but don't be surprised if you end up in here again if we need to chat." Rose continued with a grin.

She walked closer to Dean, who had put the fire out, and pressed two fingers to his forehead. He was used to the drill - close your eyes and bend your knees. He was in the room when he turned around only to see the blonde vanish into the air.

Dean sat down and cradled his head in his hands. How was he going to talk to Cas about this without saying something completely embarrassing? Dean sighed and lay back onto his bed.
