Doctor's POV:
The words Rose had spoken, and the kiss on the cheek left the Doctor dazed, he stood in shock for a brief moment before Jack's voice brought him back to reality. "Come help us will you?!"
The Doctor shook his head to clear it, walking over to help the duo pick up papers. Sadie was darting around trying to help by gathering papers for her sister. As the little girl ran off once more she was distracted by the bowl of fruit sitting on the table that the Doctor had jumped over earlier. "Rosie!" Sadie called to her older sister
Rose turned to look at her sister, her eyes glimmering in the florescent light of the lobby. "Yes Sadie?" The blonde walked over to the girl who gestured dramatically at the bowl of fruit. Rose smiled and pulled from it a banana and peeled it before handing it off to the little girl, "Don't pick up any more papers until you've washed your hands!" Rose called after her as she ran off again; she stared after her for a moment more before turning and walking over to the Doctor. The blonde must have seen the quizzical look in his eyes, because she spoke before he had that chance. "She wanted a banana…banana's are good."
The tall brunet smiled at her impression of his past incarnation, "Well they are." He laughed.
Slowly and tediously as the night went on they managed to pick up the papers and put them back where they belonged. Somewhere during the process Sadie had fallen asleep on one of the sofas in the lobby. Now they were finally making the room look less like a paper mill, but the Doctor nearly dropped his papers when Sadie woke up shrieking.
Rose darted from her office to the little girl's side, and he had to admit he was in awe of how quickly she calmed down and put the tiny sniffling human back to sleep.
When the older of the two sisters stood back up to continue working with the paper, the Doctor called out to her quietly, "Was she okay?"
The blonde looked up her eyes dark, and walked over to him. "Yeah…she just has some pretty fierce nightmares."
Suddenly a curious feeling of urgency came over him as he remembered a seemingly harmless piece of information, Rose told Sadie their adventures as bedtime stories. "Rose…what was her nightmare about? Did she tell you?"
Rose looked distraught as she whispered her words, "The Daleks."
The Doctor tried to push the tone of anger from his voice, but it slipped through anyway, "You told a four year-old about the Daleks?!"
The blonde's head shot up and her eyes were alight with indignation as they met his, "No!" Suddenly the flame of indignation was replaced with regret, "Sorry…I didn't mean to snap. "No I didn't tell her about them."
Now the Doctor was truly confused, who else could have told her, Jack maybe, but he doubted that. "Then how does she know about the Daleks?"
Rose hung her head, putting her hands over her face. "It's my fault! She lives around me!" Her outburst took the Doctor by surprise.
Surprise was quickly replaced by worry as his mind raced over the possibilities, "Have the Daleks attacked you?!"
Rose looked back up at him quickly, "I thank any power that may be that they haven't." Her gaze flitted for a moment over the little girl, "No…but she is so much like me…she can see very small parts of time."
If he was confused before, now he was completely lost, "What do you mean? What's that have to do with this?"
Rose's voice was hardly audible as she responded, "The Time Vortex, the heart of the TARDIS…part of it…a very small part as left after you extracted it from me. Over time it became stronger…until I could see all of time and space again." The Doctor would have thought she was joking if it wasn't for the deadly serious tone in her voice.
"How- that's not possible," The Doctor struggled to find the right words, "You should have burned by now!" He mentally slapped himself at his outburst.
Rose smiled sadly, "No…it's like an antibiotic…after you use it a few times the disease becomes immune to it, in this case I'm the disease." She looked up at him and he could see the gold light of the time vortex intertwined with her hazel irises, and he wondered how he hadn't seen it before. "Have you ever heard of Time Angels?"
The Doctor thought for a moment and in the depths of his memories he recalled something he had been told centuries ago on Gallifrey before he was told to look into the Vortex himself, "Yes…once. They are incredibly rare, so much so that even TimeLords hadn't really had the chance to study them. All we knew was that they were made, not born…and they could travel space, time and universes without even a vortex manipulator."
Rose's eyes seemed to actually shine now with the intensity of her manner, "I know." She turned from him and took a small mechanism from the table, "This is a life-form scanner."
She pressed a small button on the side and a green light showered over him, when it cut of a robotic female voice projected from it, "Species TimeLord. Known to have two hearts, and capable of regenerating in the face of death, but only twelve times."
Rose handed the small object to the Doctor and he looked down at it with curiosity, "What do you want me to do with it?"
She stood a little straighter, looking at the scanner in his hands, "Scan me." He pressed the button on the side as she had done, and he was rewarded with the same shower of green light.
"Species Time Angel. Known to be able to travel in time and space." The Doctor was shocked at what the female voice said, but that couldn't prepare him for what it said next, "Previous species, Human Female and TimeLord."
He glanced back up at Rose to see a pair of wings behind her that looked like they were made of star dust. They were completely gold, and yet they seemed to shift between every color in the spectrum, the only word he could find to describe them was; angelic. Each one was at least three times the girl's height and shimmered at the slightest movement. They cast a glow on Rose's face that made her seem even more graceful, which the Doctor hadn't thought possible, and in the same breath made her deadly powerful.
"Bu-But how?!" The Doctor struggled to formulate a coherent response.
"Time Angels are made not born," Rose quoted the scanner, "From exposure to the Time Vortex."
"And you're-" For once in his life, his voice failed him, he couldn't find words through his awe.
Rose let her wings glisten into disappearance before she spoke, "A Time Angel…Yes I am." She looked up at him her eyes once again their normal hazel. "And I'll go ahead and answer your next question before you ask it. For a human to become a Time Angel is a difficult process, a human heart can't handle both the blood and time energy that must course through it, so they must first make the transformation into a TimeLord, before becoming a full Time Angel."
Rose's POV:
Rose was shocked by the Doctor's response, he pulled her into a tight embrace, "I can't believe it! You're more powerful than me!" When he pulled back he spoke once more, "I could learn so much from you!"
She couldn't help but smile up at the one person in the universe she held on a pedestal above anyone else. His fascination had always been part of what she loved about him, "I'll be happy to tell you anything you want to know but only if you promise not to tell anyone else…not even my family knows."
"Your secret's safe with me." He promised looking down at her.
Rose looked away, her heart sinking as she thought of an awful truth, "There is one more thing."
"What?" She could hear the concern in the Doctor's voice, but she didn't dare look at him.
The blonde took a deep breath before she spoke, "Being a Time Angel…it makes you immortal."
"You'll finally understand what it's like to be me." His words took her by surprise and she looked up to see his eyes were sad as they always looked when he thought about the fate of Gallifrey. "You know what I'm going to tell you, but I still have to say it…you're going to out-live all your friends and family…including me eventually. The sooner you come to terms with that…the better off you'll be." His voice seemed quiet in comparison to the churning of the machines in Torchwood Tower.
For the first time in quite a while, Rose felt a glimmer of hope, "It doesn't necessarily have to be that way."
"What do you mean?" The look of perplexity that crossed his face actually made her giggle.
"If you are exposed to a very small portion of the Time Vortex, then you can become a Time Angel as well." Rose looked up at him hopefully, praying that he would agree, "And the transformation wouldn't take as long for you, because you're already a TimeLord…it would only take a few hours, a day at most."
He looked worried at the idea, and Rose tried not to let her disappointment show. This was her only chance to have someone she cared about by her side for the rest of eternity. She had already accepted the fate of her family and friends, but she wasn't sure she could accept that same fate for the Doctor. "How would I be exposed to the Time Vortex…because I'm not exactly eager to look into the heart of the TARDIS."
Rose's hearts soared, he hadn't completely dismissed the idea, and she knew the solution to his dilemma, "You won't have to do that, if I have your permission I can do it myself." She smiled up at him, "For your first lesson about Time Angels, I can tell you this, if a Time Angel deems a person worthy and good-hearted they can transfer a small part of the Time Vortex into them and let them too become a Time Angel to help carry the burden of the universe. That's how Time Angels are usually made, but I didn't follow the rules…never really have to be honest."
The Doctor laughed, his good spirit infectious, so Rose couldn't help but feel high-spirited. "You have my permission, and I'm honored that you think I am 'worthy and good-hearted' but how does transferring the Time Vortex work?"
Rose looked up at him cheekily, "Like this." She touched his shoulder gently with two fingers, feeling the power of time and space rush through her fingertips.
He jumped back slightly, "Ow!"
"Sorry, I should have told you it feels like an electric shock." Rose said joyously as the Doctor rubbed his shoulder, "But on the bright side, you should be a Time Angel by the time the TARDIS is ready to fly."
