Unstable Travelling (the 11th doctor x reader)

Doctor Who?

As the day dragged on slowly you decided to go for a walk to pass the time plus you needed some air, your flat was stuffy and not that much sunlight was let in since you always had your curtains closed so you grabbed your coat and walked outside. It was cold since it was just about winter so you kept your hands in your pockets. when you arrived at the park you sat down on the swing and started to drift into thought about the text you had gotten earlier that day from 'The Doctor' who was he, how did he get your number and how does he know you cut yourelf? all these questions swirled in your head but then you were snapped out of thinking when a man walked up to you.
"hello (y/n)" you looked up at the man he was wearing a brown jacket with dark yellow patches on the elbows, he wore a bowtie and troiser straps which held up his black trousers, he was also wearing a white button up shirt and a red fezz.
"who are you" you asked
"im the doctor" he said with a big grin waiting for you to say something in response. so this was the doctor.
"how did you get my number" his happy face changed to an annoyed one
"no thats not what you say your ment to say doctor who? not how did you get my number that just ruins it" he said quite annoyed at what you had said
"oh......sorry" you said awkwardly. there was a silence for a minute until he started speaking again.
"anyway london is in terrible danger and if we dont stop what going to happen london will no longer be the capital of britain" as he spoke he moved his hands and gestured a lot.
"is that such a big deal" you said smiling slightly
"yes it is because i mean london wont be the capital because he wont exsist because it would have blown up" he said seariously. your smile quickly went after he had said that.
"oh okay that is a big deal"
"yea it kind of is. so....." he looked at you and you looked at him confused.
"so......what" you asked for an answer.
"will you help me" you looked at him not knowing what to say
"ummm.....why me"
"because your smart and brave" you giggled for a couple seconds
"i am kind of smart but how am i brave?" you question
"this is a sad reason but when you cut yourself you don't hesitate at all" you looked at the ground then looked back up at him.
"i don't know will it be dangerous"
"very" you were intrigued by his offer and it being dangerous oh how could you refuse an actual adventure with danger and life risking situations.
"okay i'll help you but as long as i dont die"
"cant make any promises"
"all the more reason to help out"
"great i'll meet you at st. James park on the 5th of november ok"
"ok" you looked to the ground then looked back up to where the doctor was.
"but doctor-" he was gone. you stood up and looked around the park. no one except you. you decided to ponder about it while walking home. when you did get home you had a text from your older brother.

hey its the 5th of november want to come down to bristol to see some fireworks mum and dad will be there

you ignored it as usual and put your phone down, you then put on your pajamas and your hoodie because it was 6:00pm and it had gotten dark. you must have chatted to the doctor for about an hour or so and it took you about half an hour there and half an hour back so you had been gone for two hours. you didnt watch any tv that night you just went to sleep or tried anyway but you thinking about what the doctor had told you about london being in danger was pondering in your mind but from being so tired from the restless nights you eventually fell asleep.
