A couple of you were asking how the butterfly writes...I guess that's my fault for not making myself clear. Basically...magic, it's not a normal butterfly. And also in case you were wondering, Jack, Donna and Martha know about the Thames thingy cos of the TARDIS, but if you have your own idea about that then that's fine with me I just forgot that they didn't know and accidently put it in, so I put it down to the TARDIS telling them about it and that there was no need to panic.

Hope that's cleared things up for you, guys. If you have any other questions please let me know. XD Thank you!

The Doctor awoke the next morning feeling a lot better than he had done recently. He put it down to getting a good night's sleep. Thankfully without any dreams/nightmares. He also felt a lot happier than he had done, he didn't feel the need to drink to make himself feel better. However it was still only morning, so that could all change by afternoon.

Once he was fully awake, the Doctor sat up in bed and looked for the light on his bedside table. He turned it on and saw that on one of the pieces of paper was a note. He picked it up and read it.

'Please let Jack, Martha and Donna help you.'

The Doctor looked confused. Who had left this? The Doctor looked around his room, trying to see any sign of anyone (or anything thing) that could give him a clue to who had left the note. The Doctor looked around his room until his eyes settled on the end of his bed, where a small rose-red butterfly sat looking at him. The Doctor continued to look at it as it flew onto his lap.

"You left this, didn't you?" The butterfly nodded and the Doctor was taken aback. "Who are you, and why are you following me?" The butterfly just looked at him. "Come on tell me, or write a note telling me, however you communicate." The Doctor was starting to get annoyed with the small creature on his lap. He just wanted to know who or what is was and why it was following him. "Please tell me, this is the third time I've seen you now." The Doctor lowered his voice to a more comfortable level.

The butterfly looked at the piece of paper that the Doctor was holding. He looked at it. A new note had appeared.

'I can't tell you who I am.'

"Why?"

'It's complicated.'

"That sounds like something Rose would have said."

'She misses you.'

"How, she's not here."

'Yes she is, just not in human form.'

"How do you mean? Like a ghost?"

'Not quite.'

"Then how?"

'Think about it when you're back to your normal self.'

The Doctor couldn't believe that he was talking to a butterfly. The world had suddenly become a much stranger place.

"Can you tell me how you know me?"

'No.'

"It's complicated, isn't it?"

'Yeah,'

"OK, guess I'll just have to figure out who you are. I'm gonna go now, why don't you flutter off somewhere?" The Doctor got out of bed and the butterfly flew off his lap. He looked at the paper for the butterfly's response.

'Can't I stay with you?'

"Why?"

'Because I'm all alone.'

"So am I, all right then. Is there another way to communicate other than this?" the Doctor held up the paper.

'I've always wanted to try telepathy.'

"A telepathic butterfly, whatever next?" The Doctor laughed. It felt good, he hadn't laughed in so long. Maybe he was starting to recover. There was something about this butterfly that reminded him of Rose and how she used to act around him.

"Yeah, whatever next?"The Doctor had heard that, he looked down at the paper and found no message. He smiled at the butterfly. Its voice was feminine and had a musical sound to it, with a hint of Rose's voice in it, which made the Doctor think more of Rose.

"Let's go," The Doctor sent back. He and the butterfly walked out of the bedroom and into the kitchen where the others were.

"Morning," the Doctor said as he walked in. The butterfly flew over to Jack and landed on his shoulder.

"Morning, hey how did this little thing get in?" The butterfly looked at him and Jack failed to notice.

"Dunno, I found her at the end of my bed this morning." The Doctor said. He grabbed a banana and sat down. The butterfly flew onto the banana and tried to take a bite.

"Hey," he said and shooed it off.

"You seem happier this morning." Martha said to him.

"I feel it too. Dunno why, I think I had a goodnight's sleep." The Doctor told them.

"You look a bit better as well." Donna told him.

"Feel it,"

"How come this butterfly is all over you?" Martha asked.

"Dunno she said that she knows me."

"She said?"

"Yep,"

"She's just a butterfly," Donna told him. The butterfly flew onto the table in front of Donna and gave her a stern look. Not that Donna noticed.

"I think you've annoyed her." The Doctor looked at the butterfly on the table.

"How does she speak?"

"Well first of all, she left notes. Yesterday she wrote them in the ground and this morning I found one on paper. Must be some sort of magic. And now I can communicate with her using telepathy." The Doctor told them.

"Right, not your common butterfly then?"

"No,"

They ate in silence for a while. The butterfly flew around the kitchen and occasionally she would land on the Doctor and Jack and fly off again.

"She seems fond of you two." Donna noticed.

"I know them, that's why."

"Whoa that was weird."

"What was?"

"She just spoke. Didn't you hear her?" Donna asked. The others shook their heads.

"Telepathy Donna, she was speaking to you inside your head." The Doctor told her. "What did she say?"

"She said that she knows the two of you."

"How does she know me?" Jack asked. "We've gathered that she knows the Doctor, but how does she know me?"

"It's complicated." The butterfly told Jack.

"That's what they all say." He said back to her.

"She told you it was complicated, didn't she?" The Doctor asked.

"Yeah,"

"Said the same to me. Oh and don't ask her who she is, you'll get the same response. Had a good chat with her this morning." The Doctor replied, he put his banana skin in the bin and headed for the door.

"Where are you going?" Donna asked him.

"I'm going to go out." The Doctor replied.

"All right, just don't try and kill yourself."

"I won't, I'm not in that kind of mood today." The Doctor told them. He left the kitchen and walked down the corridor towards his room to get dressed. The butterfly followed him.

Jack, Donna and Martha watched him and the butterfly leave. All wondering the same thing: Who was that butterfly?

...

The Doctor entered his room and grabbed his clothes before heading into the bathroom. The butterfly followed him, but as the Doctor got to the door he looked back at her with one eyebrow raised.

"No, you cannot come in. Wait here." He told her.

"But,"

"But nothing, you are not coming in." The Doctor smiled at her before closing the door, leaving the butterfly on her own. She flew around the room before settling on the bed and waited for the Doctor to return.

She didn't know how long she had been waiting for when the Doctor came back out. He was dressed in his normal clothes and his hair was still damp from the shower. He sat on his bed and the butterfly flew onto his head as he grabbed his shoes and put them on.

When he was done the Doctor left his room, the butterfly in tow and walked down to the console room and set the controls for the country side.

When they had landed the Doctor grabbed his coat and left the TARDIS. When he got out side he put on his coat and the butterfly sat on his shoulder. It was a bright day and it was fairly warm. The Doctor saw a bench over on the hill, walked over and sat down. The butterfly sat on the bench beside him.

The view was fantastic. The Doctor wasn't sure where they had landed but he didn't care. There wasn't anything bad going on, he didn't feel bad or upset or anything like that. He felt content and happy for the first time in months. The thing that pondered on the Doctor's mind was how long it was going to last. But he was going to enjoy it while he could.

"Beautiful, isn't it?" The Doctor said.

"Yeah, makes you forget all of your troubles." The Butterfly replied.

"Not all of them." The Doctor sounded sad and lonely now. His hearts dropped as he saw a couple walking in the distance holding hands and laughing. It reminded him of him and Rose and how they used to be before she died. He continued to look at them and it was only when he felt tears form in his eyes that she turned away. The butterfly looked at him and then where he had been looking. She too felt upset and she felt her own heart drop. She then looked back at the Doctor who was looking down at the ground, tears falling from his eyes.

"Are you OK?" The butterfly asked him.

"No, I miss her."

"I didn't know she meant so much to you."

"If you'd have met her, then you would have seen how beautiful she was and how much she loved life. I miss her more than anything. I wish I could let go, but I can't. I don't think I ever will." The Doctor told her.

"Nothing lasts forever, Doctor. It all comes to an end. Everything has it's time. Remember what Sarah-Jane said?" The Doctor looked at the butterfly.

"How do you know about that?" The Doctor stood up and looked at her. "How do you know what she said? You weren't there!"

"It doesn't matter how I know. All that matters is what she said." The butterfly replied.

"No it does matter how you know, it matters to me. I want to know who you are and what you're doing here." The Doctor thundered at the butterfly.

"I know because I was there!" The butterfly bit back.

"How were you there? I didn't see you."

"You still haven't worked out who I am yet, have you? I would have thought that was obvious, but apparently I was wrong." The butterfly flew off leaving the Doctor on his own.

"No wait, come back. Don't go!" The Doctor called after her, but she was too far away. The Doctor sat back down and cried.

He didn't know how long he had been there, but he soon felt tired and so he lie down on the bench and fell asleep. He dreamt of the butterfly and he dreamt of Rose...

The Doctor was standing in a field along with Rose's ghost. She was still the most beautiful girl he had ever seen, even if she was dead.

"I miss you, Rose." The Doctor told her.

"I know, I'm sorry." Rose told him.

"Can't you come back?" The Doctor asked her, the ghost shook her head.

"You know that that's impossible."

"Why did you have to go?"

"Because it was my time to."

"You were too young."

"Maybe, but maybe that was my fate from the moment I was born. Maybe I was always meant to die young."

"No, no-one is born to die young." The Doctor told her.

"There's nothing you could have done." Rose told him.

"But if I had seen that you were getting ill, then I could have done something." The Doctor told her.

"We had this conversation the day I died Doctor, let's not go through it again." Rose told him smiling. The Doctor tried to smile back. "I've been watching over you, Doctor. You've changed." Rose told him, "You're not the same man I love."

"I know I've changed, but I can't help it. I'm still grieving."

"There must be other ways to grieve. Getting drunk every night and trying to throw yourself into the Thames aren't the best ways."

"I have depression apparently." The Doctor admitted.

"You were all right today though."

"Yeah, today, but what about tomorrow, or the day after. I could be trying to throw myself off a cliff." The Doctor told her.

"Then control yourself. I'm not always going to be there trying to save you." Rose told him.

"You weren't there last time."

"Yes I was, I saved you. If it wasn't for me, then you wouldn't be here."

"I thought it was that butterfly that saved me?"

"You still don't have it, do you?"

"What?"

"Haven't you worked it out yet?"

"No,"

"Doctor, that butterfly knows both you and Jack, right?" The Doctor nodded. "She knows what Sarah-Jane said that day in the school. Doctor you said yourself that she reminds you of me. And you missed her last message at the Thames. She wrote down, 'I love you'. Who would say that? Who knows both you and Jack? Doctor, think about it, please for me. I don't want to tell you, I want you to work it out for yourself." Rose told him. She began to fade.

"Rose, don't go, please don't leave me." The Doctor told her.

"I'm not leaving you, Doctor, I'm always with you." Rose was completely gone now and in her place was the rose-red butterfly that had been following him around...

The Doctor awoke with a start, almost falling off the bench. He had it; he knew who the butterfly was now. He shot up and looked around for any sign of her, but couldn't see anything.

"Butterfly, where are you? I'm sorry; I didn't mean to shout at you. I know who you are!" The Doctor called. "Rose, where are you?"

Finally he knows who the butterfly is! Hope you liked that one!

And, by the way, if you haven't already guessed, the chapter titles are lyrics from the song. It's hard trying to find lyrics that fit with each chapter, but I think I'm doing all right! XD

OAO
