Hi this is a Jacob x reader story, so yup, enjoy! It's also got some Evie x Henry parts in it. I know the train doesn't actually have rooms but I just added them. By the way:

y/n - your name - (hey if you don't want yourself to be in the story make up a character. Go crazy.)

s/n - surname

h/c - hair colour. bla bla you probably already know sorry to slow ya down.

(Y/N)'s POV

"So, just make yourself at home, y/n," Evie said as she ushered me further into the train. Wow. Wow, yesterday I was just a wandering, lost girl roaming the London streets, and in what seemed like an instant, I had become one of them! The Rooks.

"Thankyou, Miss Frye," I laughed.

"Oh, no no, formalities really aren't neccesary, just call me Evie," Evie gave me a reassuring smile.

"Thankyou, Evie."

"You're very welcome. Oh, and uh if you see Jacob, just run away. That thing doesn't do anyone any good. Well, don't hesitate to ask anyone anything, bye now," She smiled again and walked off.

I really didn't know what would happen from now on. That was it. He just appeared in my life and now my life had changed. Jacob Frye.

Aaaand speak of the devil, he was striding down the train car. I caught his eye and he smiled at me."Ah, it's you. Miss (s/n)," He held out his hand.

"H-hello there Mr Frye it's nice to see you," I said quietly as I shook his hand. I smiled back. His hand was warm and comforting, like it always was.

Flashback/

I sat by the lake, enjoying the beautiful breeze and the radiant sunlight that highlighted the grass and trees in such an interesting way. A mixture of blues, greens, and yellows danced around before my eyes, but then something red came into view.

"Hello, what do we have here?" A strange man sauntered up to me, and his friend followed suit. Blighters. This could only end in misfortune. They started to close in on me. "What'cha got, lady?"

"Yeah, you seem like the rich type,"

I stood up. "Get away from me."

The two men laughed. "Oooh, or... or what. What, dear, will you do?" one taunted.

"You don't want to find out, I assure you," I growled.

"Let's take care of her," the man smirked. As he came to attack me, the most absurd thing happened. A man flew out of the sky and his shoe hit me in the face. He stabbed the two men swiftly and skilfully. They fell to the floor and the strange man drew his weapon.

"Ow..." I groaned.

The man spun around. He wore peculiar but intriguing clothes, and a top hat that suited him perfectly. The many colours in his eyes seemed to dance around."So sorry," he laughed.

"Oh, it's quite alright. Thankyou, for helping me." I passed him back his shoe.

"Oh... hmm that's weird, you aren't running?" He asked, slipping his shoe back on.

"Why would I?"

"I don't know, most of the people I save just run and scream."

"Without even saying a word, even though you saved them?"

"Yes, usually."

"I'm not scared at all. You get used to these things..." I tried not to look at the two dead men on the ground. "May I ... ask your name Sir?"

"Frye. Jacob Frye. Nice to meet you Madam."

"It's y/n. y/n s/n."

"y/n... well I did drop in and help, but you seemed to have things under control there..."

"Oh, uh, well you could say I've learned to defend myself, yes."

"Well, would you like to join me and the Rooks?" He proposed, spreading his hands out when he said 'Rooks'

"The... Rooks?"

"We fight to free London from these Blighters and Templars. The people deserve to run their own country," Jacob said looking into my eyes so that I couldn't avert mine. I could tell he was very passionate towards the cause.

"And I could help?"

"I'd like you to."

"Well, why not. I'd love to join the Rooks, Mr Frye."

He held out his hand. I gave him mine and we shook hands. I felt like this was the start of a great... companionship.

"JACOB!" A lady's voice rung out from behind me.

"Oh bloody brilliant, it's her."

A brown-haired woman with stange clothes like Jacob's walked up to us. She looked angry."

"YOU were meant to wait over THERE what are you DOING?" She demanded.

"Well, dear sister, I was helping y/n here. She's a new recruit now."

The lady turned to me. Her scowl transformed into a smile. "I'm sorry I didn't even know you were there! I'm Evie Frye, what's your name?"

"She's y/n s/n and if you'd be so kind, oh beloved sister of mine, show her around the train, I really need to see Greenie. You jealous?" Jacob answered for me.

"N-no I am not - just leave, Jacob." Evie looked to the floor and blushed. I was so confused. Greenie?

"Well i'm off. I'll see you later y/n!" He zipped off.

/ End Flashback

"You know, I don't know what it is about you , y/n, but you just might be my favourite rook," Jacob laughed.

"I - well thankyou Mr Frye." I tried not to blush.

"Ugh Evie's back," Jacob groaned, pointing behind me.

"Ah, Miss F - Evie, what's wrong?" I asked.

"Jacob I need to talk to you, stop disrupting y/n,"

"Sorry, y/n, good luck with the moving stuff." He patted my shoulder.

"Thankyou, Mr Frye, Miss Frye. See you later then," I walked away.

"Evie," Evie called after me.

"Right sorry, Evie!"

Jacob's POV

I collapsed onto the sofa behind me. "Ugh, killing people. Such hard work," I sighed. Evie scowled. "What's that for?" I asked.

"You are so annoying. But I need you to listen to me now." She looked at me sternly.

"Alright, alright, I'm all ears."

"Good. All ears. No mouth."

"B-"

"No. Mouth. Phew, okay here goes. I can't perform an assasination that needs to happen. I need to be somewhere else, and so that leaves you to do it."

"That's great! Who, who do I kill?"

"No Jacob, it's still listening time. This is to be a low profile assasination. LOW-PROFILE, is that clear?"

"Crystal."

"And by low profile I mean you need to blend in. A ball is taking place at the location, so you will be disguised as an upperclass man attending."

"A disguise? Have you been in touch with Freddie?"

"As a matter of fact, I have. He gave me your disguises for the evening."

"Disguises?"

"Yes you'll have a partner. A girl. Choose any one of the female Rooks."

"Ah. Do they... have to be experienced?" I asked, thinking of no one in particular...

"You want to take y/n."

"Wha- well if you insist."

"I didn't insist I really don't ca-"

"If you think she's the best option. Well i'll just go find her then." I stood up and stretched. "Good luck with Greenie, and before you ask, yes I will walk you down the aisle."

"JACOB!"

"Yes? Oh right i'll organise the cake too."

"You little-"

"Charmer. Oh, I know." I walked off feeling smug and I could just feel Evie dying behind me.

"I - hope you die!" She yelled.

"Ditto."

I jumped train carriages and eventually found y/n. Well her room anyway. She'd been given a special room because she was actually now our travelling nurse. Along with fighting, y/n had some medicinal abilities too. She was talented indeed. I knocked at the door.

"Yes, who is it?" her voice came from inside.

"Only your favourite person in the world," I replied.

"Well, come in Mr Frye."

I opened the door to see y/n in Rooks clothing. "So I am your favourite person then?"

"Who knows. I just recognised your voice. These clothes are strange. Why the colour Green?"

"Hmm... I don't know. Ask Evie."

"Am I missing something? You keep mentioning 'Greenie' around Evie."

"Yep. If I say anything she'll kill me but here's a hint. She loves Greenie. A lot. Your clothes really look good on you though." I complimented. And I actually did mean it. I had never seen the Rook uniform look so good on someone.

"Thankyou..."

"Ah, yes, I came to ask you if you would join me on a mission."

Y/n's eyes brightened. "A real mission?!" She bounced around. She cleared her throat and regained her composure. "So, a mission?"

"Yes, and a special one at that. We'll be disguised as a couple."

"A - a couple... Well of course i'll join you, Mr Frye."

"Y/n, you can call me Jacob, you know."

"O-oh I couldn't." she looked to the floor.

I laughed quietly. "Well i'll bring you your costume and we'll go to the carriage Frederick Abberline arranged for us. He's a master of disguise.

I waited at the carriage for y/n. I felt so weird in these clothes. Suits were not my type of thing, and neither were ties. Too fancy for my liking. In the distance, I saw a figure running down the stairs.

"Sorry! Sorry i'm late, I just found it so difficult to wear this thing!" y/n came into view. She looked absolutely elegant in her long, flowing, purple ballgown, and her h/c, silky hair was done up in a very confusing but impressive way. Her hands were covered with white gloves that were embroidered with intricate purple flowers. "Wow, you look fancy," she giggled. She looked oblivious to her own beauty. Not that I thought she was beautiful or anything... okay fine maybe a bit.

"I was just about to say the same thing. You look great!"

"Th-thankyou, but this dress is so - well, poufy. How many layers can one gown have?!" She sighed. "You aren't wearing a hat or a hood or anything! Wow I never thought i'd see the day."

I ran my hand through my hair. "It feels weird with out something on my head."

"It doesn't look weird, don't worry. You look rather handsome - I mean - well, we should leave now, right?"

"Yes we should get going."

"I mustn't forget, Evie told me to keep an eye on you."

"Ha ha while she keeps an eye on Greenie," I sneered to myself, as I opened the carriage door. "After you, my lady."

"My lady?" y/n laughed.

"Yes, we're in disguise so we have to play the part, my lady."

"Well, then thankyou kindly, Mr Frye," she stepped into the carriage, and I followed.

(Y/N)'s POV

Jacob did not seem aware of the torture he was putting me through. He would make comments like 'I like you' and 'You are the prettiest Rook if you ask me' without even realising that I was blushing like crazy. He even told me he wasn't sure what my eye colour was and stared into my eyes for an age. His eyes sure were intriguing. Wait I did this before, I looked at his eyes and thought wow those eyes and then I - but wow his eyes - wait I was getting side-tracked - who was I again?

There was something about Jacob that really made me happy. He was nothing like anyone else I had ever met.

"y/n?" Jacob brought me back to reality. "Are you okay?"

"Perfectly fine, ha ha!" I laughed sheepishly. "Oh, we're here!"

"Yes time to kill some- oh I mean time to blend in and make sure no one sees me kill the guy," Jacob corrected responsibly.

"Ja - Mr Frye, Evie briefed me on the mission, so you can follow my lead." I explained. "Although it's a bit hard to be productive in this damned gown."

"Well you look good anyway. Lead the way, y/n." I tried not to blush at the comment (to no avail). I hopped out of the carriage and Jacob did too. There were many couples around, all holding hands and linking arms.

"Psst!" Frederick whispered from the driver's seat. "You guys need to act like a couple or the disguise won't work!"

"Alright Freddie, that'll be all. Off with you now." Jacob waved Mr Abberline away. Without a word, he gently placed my arm around his. I hugged his arm. "Is this couple-y enough?" he asked me quietly.

"I would imagine so. A-anyway, first things first, we need to identify the target."

"Good idea," a smirk played across Jacob's lips, "my lady."

I gulped. This would be a long night.

Evie's POV

I had been collecting Henry's pressed flowers, and each time I brought one to him, his face would just light up. I never got tired of his reaction. From time to time I would think about how I shouldn't get too close to Mr Green. Jacob had reminded me on many occasions that an assassin should never allow personal feelings to compromise the missions that had to be done. I would never allow that to happen... but what if it got in the way? I tried to ignore those thoughts. I enjoyed Mr Green's company. He was so kind, calm, sensitive and- oh god I needed to lie down. Well I would collect his flowers nonetheless.

I was walking the streets of Whitechapel, enjoying the unusual peace that had settled in the borough. The night air was cold but refreshing, and it was nice not having Jacob around to tease me. He said the most absurd things sometimes.

Although... I had a feeling he was interested in the new recruit, y/n. Who could blame him, she was very likeable. Jacob had the weirdest personality. He was he type of man that was oblivious to his own feelings even if they were as plain as day. He would think 'She is the nicest girl i've ever met' and think nothing of it. I doubted he would ever get anywhere with y/n. Well who knows? Fate reveals itself in different ways. Maybe fate would let Henry and I... never mind...

Jacob's POV

We had entered the mansion, and tried to fit in with the other rich people. I wasn't quite good at fitting in, but y/n looked so amazing, she easily passed as one of them. Ugh they were so snobby, and most of them were Templars. Resist the urge to killlllll. y/n was holding onto my arm, and it was actually very comfortable.

y/n leaned over slightly and whispered,"Ja- Mr Frye, i've located the target. Now our job is to lure him out at a good time-" She was interrupted but the string quartet that started playing, and all the couples started to dance. "Now is not a good time. Right now we have to do what these people are doing. We don't want to stand out. Now what are they doing..." y/n looked around a everyone else. She let go of my arm and then placed her delicate left hand on my shoulder. She gently placed my right hand on her waist and then with her right hand, entwined her fingers with mine.

"Sorry," y/n said softly.

I gulped. Being this close was making me nervous. And I rarely ever got nervous. "It's fine, this is our job right?"

She nodded."Right, our job. But I have no idea how to dance!"

"Well, sorry but I can't help you there. You're talking to Mr Two Left Feet here."

"Okay, well we'll just follow everyone else's lead."

"Right. You follow their lead, I'll follow yours."

y/n laughed nervously. She moved her foot, so I moved mine, then she did again, so I did - and before I knew it we were actually dancing. The footwork wasn't so hard. It was sort of how I moved my feet when free running, climbing buildings, that sort of thing. It was actually very enjoyable, dancing with y/n.

"Oh no, they're about to do the twirling," y/n pointed out.

"I have to spin you around?" I asked.

"Yes, but please don't let me fall, this part seems kind of scary."

"I promise I won't. This should be easy." When the other couples did, I let go of y/n with one hand and twirled her away, then brought her back into a dip. I brought my face close to hers. Her eyebrows slightly raised and her long eyelashes flutterred in the most entrancing way. Her eyes met with mine.

"So, this is fun," I murmured.

"Yes it is," she said quietly.

I pulled away and we returned to our original pose. The music came to the end and people started applauding. We broke away and applauded too. Eventually, people scattered a little.

"Phew that was exhausting," y/n sighed. We both laughed. "Now to lure the target away from the crowd."

I smiled at her. "Looking forward to it."

I hid the target's body in a hay bale, with y/n's help.

"Mission accomplished!" she sang. "My first task was a really fun one!" Her eyes glistened.

"Yes, actually the whole disguise thing was bloody brilliant," I laughed. "Well we better get going before someone realises what's happened."

"I agree. Thankyou for letting me accompany you today, Mr Frye."

"It was my pleasure." It really was. I would invite her to join me on missions from now on.

We walked together for a while, down the streets of Whitechapel. Our conversation was very interesting and I learnt more about y/n.

"Oh, Mr Frye, look over there, it's Evie! What a coincidence!" y/n waved at Evie, and she started walking over to us. "Good evening Evie!"

"Good Eviening. Ha ha." I added.

"Why did you have to ruin it with the pun?" Evie flicked me in the head when she reached us.

"Just trying to set the mood, dear sister."

"Oh, that's right Jacob, Mr Green wanted to speak with you. He said it was important. So you need to see him immediately."

"Oh, alright then i'll be on my way. Do you want me to send him a kiss from you? I'll see you later, Evie, y/n."

Y/n's POV

"See you, Mr Frye," I waved. He started to climb a building, and before I knew it he had disappeared into the night. "Evie who is this Mr Green? I keep hearing about him."

"Henry Green. He's... an ally. He works with us, liberating London and all that."

"And... is he the 'Greenie' Jacob speaks of?"

"Oh, what did he say about Mr Green?" Evie scowled. "He's so annoying."

"He - he didn't say anything!" I laughed.

"Well, good, or I might have killed him."

"So, Evie what are you doing out this hour?" We started to walk along.

"Well I've just finished my mission, so i'm out looking for flowers. I'm assisting Mr Green in finding them all."

"So you admire this Henry Green, do you not?" I asked.

A blush rose to Evie's face, and she shook her head, hastily. "N-no of course not. Well, not in that way..." She played with her hands.

"Evie, it's okay to love someone," I comforted, and placed a hand on her shoulder.

"I do not - well... I - okay maybe a little, but you cannot tell anyone, especially not Jacob."

I laughed. "Jacob already sort of knows, doesn't he."

"Well, doesn't mean I can't stop denying it," She pointed out. She looked at a piece of paper. "Now, I can't seem to find this particular flower..." she murmured absent-mindedly.

I looked over her shoulder and saw a list of flowers. I found it so sweet that Evie wanted to collect them all for Henry. I wanted to help as much as I could."Oh I can help you!"

"Really?"

"Yes I would love to help you, Evie! When you collect all the flowers, Mr Green will be very happy. And by the way, you shouldn't worry about Mr Frye, he's only teasing."

"Well, I accept your help. Thanks y/n. You... can call him Jacob, you know."

"B-but I couldn't possibly..."

"Trust me, he'd love it if you said his name."

"He would? Why?"

"Well you like it when he says your name, don't you? Let's go." Evie walked off. I blushed, realising that what she said was true. Whenever Jacob said my name, my heart seemed to soar.

"Y-yes let's."

Over the time that we looked for the flower, I made quite a strong bond with Evie. She was a very good person, and no matter what she said, I could tell she really cared about Jacob. After a lot of searching, we eventually stumbled onto the flower. It was the red tulip - a declaration of love... how about that...

"I'd love to see you give this flower to him!" I giggled, as Evie shut the flower into a book.

"I'm actually going to give them to him all at once. That way he'll be surprised. Well, I think that's enough flower hunting for today, don't you, y/n?"

"Yes, but if you ever need help again please tell me!"

"Well, I could use your help carrying the flowers into my room."

"Of course."

We were back at the train, and I had insisted that I would carry all the flowers for her, and that she should rest. Each flower for some reason was pressed in its own little book. Carrying them all was quite a task, especially as they might have toppled over any second. I couldn't even see past the tall tower of books.

Suddenly, I tripped up on something and fell over, all the books flying out of my arms.

"Aah!" I fell into someone's arms with a loud thud.

"Ow... y/n are you okay?" I had ended up on top of Jacob, who was sprawled out on the floor, hat askew. He was wearing his normal clothes again, but I was still wearing the ball gown. The poufiness of it really didn't help the situation.

My face was an inch away from his. I blushed furiously and pulled away a little."Ahh! I'm so sorry, I wasn't looking where I was going! I didn't mean to bump into you, and trip you up. Are you alright Jacob?"

"I'm fine." Jacob looked up at me and smirked. "You called me Jacob," he sat up a little.

"I believe I did." I smiled and straightened his hat. "Oh right, sorry!" I realised I was still sitting on Jacob's lap, so I quickly got up. I knelt on my knees, next to him.

"It's fine. Oh dear, I made you drop your things," he got on his knees too. "Here i'll help." With Jacob's help, we gathered all the books that fell.

"Oh no, one flower fell out of its book!" I searched for it frantically.

"Ah, here it is," we said in unison, as we both placed our hands on the flower simultaneously. I pulled my hand away quickly. "Sorry," I said quietly.

He picked up the flower and passed it to me. It was the red tulip. I couldn't hold back a small gasp that passed through my lips. Jacob must have heard, as he smirked again. "Thankyou..." I placed the flower back into its book.

"No problem. I'll help you carry these this time." He picked up the taller half of the pile of books, and left 3 or 4 for me to carry.

"Thankyou again. We're taking these to Evie's room." I stood up and started to walk and Jacob followed.

"Evie likes flowers, does she?"

"Well, sort of."

We reached Evie's room and placed the flowers on her bed. "There, that should be good." I said. "Well I think I need to get out of the gown, it's really annoying, and the heels are uncomfortable too," I murmured to myself.

"Do they make it hard to walk?" Jacob asked, his face concerned.

"Oh, only a bit," I assured.

"But they do."

"Yes."

"Okay." Jacob wrapped his arm around my waist and scooped me up with his other arm, carrying me. My eyes widened and my heart raced.

"Jacob?" I squeaked. I felt very hot and flustered.

"Now you don't have to walk, see?" he said, his famous smirk appearing on his face once again. While he carried me I couldn't help but look at his face a lot. I He carried me to my door, and then gently put me down. "There you go."

I opened my door. "Thankyou for everything today. I think i'll really enjoy my time as a Rook."

"I think i'll enjoy it too."

"Well, goodnight, Jacob."

"Goodnight, y/n."

I closed the door behind me and collapsed on my bed. I put the heels next to me. Phew, the day was exhausting. Jacob really was something. I liked him very much. I was so tired, that I fell asleep without even changing out of my ballgown. That night, I dreamt of a top hat and a flower. That's all I remembered of the the dream when I woke up, anyway.
