AN: So I asked my friend to give me a prompt to get out of my writers block. The prompt is 'What if the Doctor had a second companion along with Rose?' so I had to figure out who this person would be and this is what I've come up with.
Name: Violet Feldt

Age: 18

Appearance: Violet stands at 5'5" with wavy brunette hair that goes to her waist. She has wide chocolate eyes and fair skin. Her eyebrows match her hair and are not too thin and not too thick. She has thick lips that are usually covered in red lipstick.

So that's about it, her outfits will be on the polyvore: violet-feldt

And without further notes here's the prologue of Travel with Us: The Story of Violet Feldt.

~Third Person POV~

Violet sat alone, arms around her knees. It was odd that there was another person here, but she felt if they talked the plastic goop would screech and send in the manikins in. She shuddered at the thought, she'd only gone to throw her gum in the rubbish bin when it stuck to her hands. It had sucked her in and brought her here. Violet didn't know how long she'd been down here, at least a week before this new guy had shown up, or it felt that way. This bloke had cowered in the corner for the past couple of hours . She rolled her eyes. "Oi you," She whispered harshly to him "Stop whimpering, they're not gonna hurt you."
"And how would you know?" He asked back in the same tone.
"I've been here a week or so," She responds "If they wanted me dead I would have been days ago." He looked at her with stone cold eyes and she reciprocated the look. Violet heard a voice other than this bloke or the living goop.
"The Nestene Consciousness. That's it, inside the vat. A living plastic creature." A northern brogue met her ear.
A woman's voice responded "Well, then. Tip in your anti-plastic and let's go."
The man responds in an irked tone "I'm not here to kill it. I've got to give it a chance." He seemed a bit smug. Violet turned to see the two, a shaved had clad in a leather jacket, and a blonde in a pink jumper. The man goes down to a catwalk overlooking the seething vat. "I seek audience with the Nestene Consciousness under peaceful contract according to convention 15 of the Shadow Proclamation." The goop in the vat flexes. Violet stands at his words. "Thank you. If I might have permission to approach?"
Violet is too busy watching the man to notice the blonde has run down to the level she and the bloke are on. She keeps focused on the man until he speaks again
"Yeah, that was always a possibility. Keep him alive to maintain the copy." She spins around noticing the bloke's wrapped around the blonde.
"You knew that and you never said?" Blondie yells to the man.
"Can we keep the domestics outside, thank you?" The man says and Violet can't help but laugh.
"Who are you?" The blonde addresses Violet for the first time.
"Violet Feldt, and you?" She asks as her mother had always told her 'even if you don't care to know.' She heard her mother's voice.
"Rose Tyler, how long have ya been down here?"
"A week." Was the answer Rose received, seeing as Violet turned back to the Man.
"Am I addressing the Consciousness? Thank you. If I might observe, you infiltrated this civilisation by means of warp shunt technology. So, may I suggest, with the greatest respect, that you shunt off?" He tells it crassly. A sort of face forms in the vat of plastic. "Oh, don't give me that. It's an invasion, plain and simple. Don't talk about constitutional rights. I am talking! This planet is just starting. These stupid little people have only just learnt how to walk, but they're capable of so much more. I'm asking you on their behalf. Please, just go."
"Doctor!" Rose yells as a pair of shop dummies grab the Doctor. One takes the vial of anti-plastic from his pocket.
"That was just insurance. I wasn't going to use it. I was not attacking you. I'm here to help. I'm not your enemy. I swear, I'm not. What do you mean?" A door slides back to reveal a Police Box. "No. Oh, no. Honestly, no. Yes, that's my ship. That's not true. I should know, I was there. I fought in the war. It wasn't my fault. I couldn't save your world! I couldn't save any of them!" Violet's eye's widened. Ship? War? Who was this 'Doctor'?
"What's it doing?!" Rose yelled.
"It's the TARDIS! The Nestene's identified its superior technology. It's terrified. It's going to the final phase. It's starting the invasion! Get out, Rose! Just leg it now!" He yells to her. Violet tries to go as he says trying to push the Bloke and Rose out. The plastic in the vat is getting extremely agitated, as the stairs fall out "Get out, Rose! Just get out! Run!"
"The stairs have gone. "She tells him. The manikins try to push the Doctor into the vat. Rose and Mickey run to the TARDIS, Violet goes back to her spot.
"No!" The Doctor yells, Violet looks around.
"Time Lord." The vat calls. She notices Rose rushing about.
"Rose!" She calls and motions to an axe and some chains. "Try that." Rose takes the axe chops through the rope holding a very long chain to the wall and takes firm hold. She runs and swings out along the side of the catwalk, kicking the two Autons into the vat. The second one also drops the vial of anti-plastic into it. The golden Nestene screams as it starts to turn blue.
"Rose!" The Doctor yells and Violet heads to the TARDIS. "Now we're in trouble." Explosions start and the signals from the Eye stop. The shop dummies start to stagger then fall over. The Doctor and Rose run to the Tardis, where Mickey is holding on for dear life, Violet shoves him off and they all go inside.
She gapes in awe. "This is brilliant," She smiles rushing up to the console and places a hand on it.
"Um…" Rose starts "Violet there's something you should know."
"What? That I'm safe from the goop?" Violet asks with a smile
"No, um… you're dead." Rose looks sorrowful
"What?" Violet's face sinks. "No that can't be."
Rose's eyes fill with tears "It was all over the papers, 'local girl burns in fire'"
"Oh so it was plastic me… but how?-"
"I'm guessing you're plastic was nearly perfect." The Doctor says "All that was left was bones wasn't it Rose?"
"Yeah, how'd you know?" Rose asks vaguely
"I had a feeling they were nearly there." The Doctor mentions. Then the TARDIS lands. Rose and Mickey exit. Violet stays rooted in her spot. "Coming?" The Doctor asks.
"I can't go back to regular life can I?" She asks him seriously
"No, but that doesn't mean you can't live a great life." He tells her.
"I think I'd like to go anywhere, but not here." Violet tells him. "You're a time traveler aren't you?" She asks bluntly.
"How'd-"
"My Aunt Mel, She told me about you."
"Mel?" He asks shocked "Wow, didn't think I'd hear that name again."
"Take me with you," She tells him more than asks. "You shouldn't be alone."
"Yeah you're right, come on then." He motions to the door. She follows. "Nestene Consciousness? Easy." He announces as they exit
"You were useless in there. You'd be dead if it wasn't for us." Rose tells him motioning between herself and Violet.
"Yes, I would. Thank you. Right then, we'll be off," He nods to Violet "unless, er, I don't know, you could come with us. This box isn't just a London hopper, you know. It goes anywhere in the universe free of charge." This caused Violet to smile.
"Don't. He's an alien. He's a thing." Mickey as Violet had heard at some point tells Rose.
"Oi! I'm going too!" She says indignantly
"And he's not invited. What do you think? You could stay here, fill your life with work and food and sleep, or you could go anywhere." The Doctor smiles a very cocky smile.
"Is it always this dangerous?" Rose asks.
"Yeah." The Doctor leans on the TARDIS.
"Yeah, I can't. I've er, I've got to go and find my mum and someone's got to look after this stupid lump, so." She tells him.
"Okay. See you around." The Doctor turns and gets into the TARDIS I follow.
"So we're just leaving her?" Violet asks and he just ignores her, he lands the TARDIS again and calls out
"By the way, did I mention it also travels in time?" a minute later Rose enters the TARDIS and they're off.

AN: So I'm sorry that I had to "kill" Violet, but it only makes sense that way she could travel with the Doctor and not have ties to home. So the outfit's on the polyvore, and it'll be the same for The End of the World. Please review if you have any suggestions
