Oi, Spaceman! The Girl from the Noble Temple

   Jack Harkness had seen lots of things - from deadly and neverending TV shows to those who wanted to end the reality itself. Right now he was on the intergalactic station in year 802,324, which meant that here everything was controlled from all sides and adapted for all kinds of passengers - from little cute things like Adipose to slimy giants like Slitheen. Nothing could predict that a trifle would break in and almost ruin all order... but trifles are such, they never care about the surrounding world attempting to stop them.
   To tell the truth, Jack only got involved in dealing with that trifle because the howling of the alarm bothered him. Pushing the way through the tightening crowd of aliens (he had to look both up and down not to squash anybody and not to bump into anyone else), he reached the doors leading to the take-off area and saw the reason of the mess.
   "Finally!"
   A human girl of about ten or eleven was feverishly attempting to open the exit hatch, but when she spotted Jack, she abandoned the trials and darted to him, having wrapped her arms around his middle, but in a moment jerked back and yelled:
   "Couldn't come earlier? You must know the way out of here!"
   "Hey-hey, wait, I'm not used to such sudden changes!" Jack exclaimed, but the girl found nothing funny about that.
   "I bet you were scared as hell when you got in such situation for the first time! Oi! What are you doing?! Let me out, old stinker! LET ME OUT!"
   The latest yelps were the result of Jack's actions - he grabbed the girl under his arm (which didn't prevent her from twitching, kicking and punching, accompanying this all with screams and shouts) and told her reproachfully, but not without a bit of irony:
   "At first you were glad to see me, and now... Would you prefer being stuck here? Confess that my society is better".
   The girl scowled at him, but ceased arching back and forwards, making it easier for Jack to carry her into the separated cabin of one of this place's employees (more like a futuristic prison cell, really, but you can't watch the unknown stars all day round from the prison cell). Communications are important, after all. Right now Jack didn't want to be bothered by the nosy aliens of all kinds (though he usually preferred right that).
   "Are we there yet?" the girl asked and huffed upon being almost tossed on the metal bed. "Hardcore aliens".
   "You can't imagine HOW hardcore they are!.." Jack recalled that his new acquaintance was a child right on time not to get into details. Instead of that, he got into other details - now he could see her head to toe. Her hair was jet-black, straight but thick, tied in a high ponytail which for now was half-undone, so locks of it were falling onto her face and shoulders. Black was the color of her brows and eyes as well, and her skin was almost chalky white, though her face was now in red spots, as it happens to some people when they are anxious. She had sharp lines of face and figure (it was especially seen in her pointed chin and fingers), and her clothing consisted of a dark pink bell-bottomed coat fastened at the top, from under which blue jeans and the high collar of a dark polo-necked jumper were seen.
   "Captain Jack Harkness at your service!"
   The girl narrowed her eyes at him, her lips pursed:
   "Captain Jack? So bring me back to the rivertrack!"
   I've seen such attitude lots of times, but why this kind of it is so familiar?.. - Jack thought.
   "So, I told you the name and title, and what about you?"
   The girl kept silent for a moment.
   "Erfin".
   "That's something tricky. I'm not as lucky". Such things work when you need to talk with a child, Jack thought.
   "Don't pretend that you're not going to laugh", Erfin muttered. "Erfin Temple. F-f-fabulous combo, eh?"
   She was definitely tempted to say another word, but held herself from swearing.
   "I didn't even think about laughing".
   "You're already doing it. All the time. Where am I, Spaceman?"
   "Spaceman?"
   "Whoever could you be? Those creatures are aliens, and you should be as well".
   "You half-guessed, Erfin. Do you know what year it is now?"
   "Whatever".
   "802,324".
   "You're crazy". Erfin undid her spoilt ponytail and clumsily combed her hair with her fingers. "And nothing more".
   "I'm more interested in how you got here. I've seen such behaviour at the beginning of XXI century... in person..."
   "One more proof you're crazy". The girl renewed her hairstyle, but two locks, shorter than the rest (apart from her fringe), remained hanging at the sides of her face. "No one could live so long, not speaking about memory".
   "You've seen aliens today, and you got to future, to deeeeeeep time and space... so you shouldn't take me as a madman. Others have already taken this role... Have you read that Alice in Wonderland thing?"
   "Mm-hmm".
   "So you know what it means to believe into six incredible things before having breakfast. One: I'm immortal. Two: I became such after a mistake. Three: I can time-travel. Four: you did the same. Five: it will take place once more. Six: you are the daughter of Donna Noble".
   Erfin let out a strange sound - something between snarling and hissing, like a vampire tickling its potential victim's feet.
   "Wanna know how I learned about this?" Jack showed the vortex manipulator fixed on his wrist. "This little thingy is useful by itself, but I upgraded it. One: there's a familiar DNA print, and not one, but two of them! Two: the second print was alien. Timelord, should I say. Three: you're one quarter alien by yourself..."
   "Four: I'm not a geek!" Erfin yelped.
   "Five: alien doesn't mean geek", Jack snapped before she could've continued - her small sharp (perhaps very firm) fists were already clenched. "Six: I'm going to get you home right now... Say, the Doctor used to say that hybrids cannot have offsprings..."
   "I think one who needs a doctor is you", Erfin murmured, arms crossed.

   The ginger-haired woman with a cell phone in her hand opened the door - she must've been annoyed by being disturbed during her oh-so-important talk.
   "Well?" she asked, her hands moving down onto her hips. "If you're a promoter of some rubbish corporation, find someone else to fool".
   "I'm not, Mrs. Temple". Jack almost called her by the name, but then thought that it would be a bad idea. There was enough kicking for him for today. "If I say the name Erfin, would it tell something to you?"
   Donna's expression changed to stunned.
   "Erfin?"
   "Erfin".
   "Erfin?"
   "Black hair, dark eyes, sharp manners".
   "So it was you who abducted my girl three days ago?!"
   "No, it was not me!" Jack pronounced in the most powerful and all-covering tone, then walked to the closest parked car and in some seconds was walking back, carrying Erfin's sleeping form in his arms (he had picked the car's alarm and had placed her inside, having thought that carrying her on his back till her home wouldn't be too attractive). "I can only say that she is safe and sound".
   Donna reluctantly allowed him to bring Erfin inside and place her on the couch, watching him suspiciously. Hah! Now you both will be safe and sound, Jack thought - he had had to wipe Erfin's short-time memory. He knew that one little recalling of the space and time events and beings (and the core of them) would burn Donna down, and such girl as Erfin would've blabbed it all out immediately (no wonder if with a bit of lie as well!), so this had had to be done. She shouldn't have remembered a single event after having accidentally jumped through the time and space warp at her backyard, which for now was closed.
   But there was one more surprise for Jack - Erfin shouted without waking up:
   "Oi, Spaceman!"
   "Dream a dream, take me, take me in your dream..." Jack hummed before he was pushed out. That was the power of memories - they were alive even after being wiped.
