(y/n) POV

It's been almost two weeks since Tatsumi officially welcomed me to the grail war, but ever since I've had to live with Tohka not that I minded it. I just missed Aunt Sakura that's all, I've only seen her once in the past two weeks and that was when she came over and set up an additional bounded field around the mansion.

Summer POV

I've been watching (y/n) to make sure he was alright. Sakura had asked me to ensure that he was eating properly and getting enough exercise. I agreed, but I would have done that either way. Especially after that talk I had with Tohka and Tatsumi.

Flashback Summer POV

"Hey Summer can we talk to you for a sec?" Tatsumi asked, "Sure I don't see why not." I said as I followed him into Tohka's private study. There were a few large bookshelves, a few chairs, a desk, a few sword cases that has three rapiers in each, and a large old clock. "Summer I would like to ask a favor of you." Tohka said from behind her desk, "Ok what do you need?" I asked, "I want you to think of (y/n) as if he were your own child." She said, "Now before you go getting the wrong idea here allow me to explain. (y/n) wanted a mother and a father to see what he achieved on his own, since you're obviously not a heroic spirit I'm pretty sure that you're here to fulfill the role of mother, and by process of elimination that means (y/n) true servant is a male." He said, "It's very possible that he summoned our father considering he is a heroic spirit, he was summoned once before by our mother." She said, "I see, well then I'll have to think about it." I said as I walked away.

End flashback Summer POV

That was ten days ago, "Summer." (y/n) said, "How did you know I was here?" I asked, "Simple I didn't feel so alone, I only feel like that when your around." He said, "Anyway we have somewhere to go." He said, "Really where?" I asked, "London, England." He said happily, "Also don't tell anyone where were going cause if you do I know Aunt Sakura or Tohka will stop me." He said calmly.

(y/n) POV

We arrived at the airport later that same day, "Ok (y/n) two things, first why are we going to London?" Summer asked, "Would you believe me if I said it was because I just had to get away from everything?" I asked, "Not a bit." She said, "Thought so, well I received an invitation from the "Queen" asking to meet with me. I know it's a trap since the letter didn't have the royal seal, but whoever sent it obviously knows about all the things my father had done for the British government." I said, "Ok and secondly how do you plan on getting a plain ticket?" She asked, "You'll see also did you bring it?" I asked, "Yeah, but I don't think your ready to use it just yet." She said as we got out of the car, "Why not? I have the best teacher in the world, I think I'm ready." I said, "Whatever your going to hurt yourself trying to use it then come crying to me." She said in annoyance.

"Hello I need two tickets to London please." I said to a lady at the ticket stand, "Oh hello little boy are you lost?" She asked sweetly, "No now about those plane tickets to London." I said, she laughed, I sighed and pulled out a leather wallet of sorts and opened it revealing an insignia.

"I am (y/n) Emiya, you will give my the tickets." I said with a commanding tone, "Oh sweetie that insignia won't get you anything now that your father is dead." A woman said with a laugh, "So you got one as well Rin." I said, "I'm your mother and I expect you to address me as so, but you are correct." Rin said, "Ma'am they are with me." She said as she handed over enough money for two tickets.

"Don't expect a thank you." I said, "Oh I don't but for the rest of this trip I expect you to call me mother." Rin said, "Not on your life, Summer's more of a mother to me in the short time we've known each other than you've been in the past eight years!" I said angrily, "(y/n) just do it. If we are walking into a trap I want you to have a powerful ally on your side at least for the time being." Summer said, "Haven't you realized it yet, I've always been your ally. Now buckle up dear we'll be landing soon." Rin said as she patted my head.

"Ah London, it's good to be back!" I said, "Wait when did you go to London?!" Rin asked, "Three years ago with Aunt Sakura, now where's our stuff." I said, "Right Archer their personal items if you'd please." She said as Archer gave us our stuff back. "Ok so we have one black cloak, one energy dagger, one of whatever this is, and one Twilight Rose." Archer said, "WOW that cloak looks good on you!" A little girl said from behind us, "WHO ARE YOU?!" I shouted as I turned to face her, she jumped down from the top of a nearby building, "Hi I'm Assassin, but you can just call me Jack." She said calmly.

 "Oh crap Jack the ripper, Summer run!" I said as I held Summers hand, "Don't worry I'm not here to kill you, Mommy sent me here to welcome you and to give you this." She said as she handed me another letter and then she vanished. "Summer were screwed." I said as I opened the letter, "(y/n) and Rin if your reading this welcome to London, I hope Jack didn't scare you too much unless it's Rin reading this, (y/n) if your reading this meet me outside the Tower of London in an hour and please come alone. Rin if your reading this watch your back, I'm going to make you pay for what you did to one of my best mates. Sincerely A." I read, "Good God that's a load off my shoulders, I actually know who this is, but Rin watch yourself she holds a grudge." I said as I walked away, "(y/n) Emiya?" A cab driver asked, "Yeah?" I said, "I'm here to drive you to the Tower of London." He said, "Summer lets go!" I said as I got in the cab, "SWEETIE what do you think your doing?!" Rin asked, "Besides actively trying to get away from you, trying to figure out why you actually care about me NOW." I said as Summer got in the car.

"Well it's about time you got here (y/n), you know its rude to keep a lady waiting." A girl said, "Sorry I got stuck in traffic Asuka." I said, "Good you remember me!" She said excitedly as she turned around to face us.

"(Y/N) WHO IS THIS WOMAN! SHE IS TWICE YOUR AGE, AND I DON'T LIKE HOW FRIENDLY SHE'S GETTING!" Summer yelled, "Who's that (y/n)? I thought I told you to come alone." Asuka said calmly, "That's Summer Rose, she's cool." I said as we sat down on a nearby bench, Asuka sat me down on her lap, I was at just the right height to where her boobs rested on top of my head. "(Y/N)!" Summer yelled, "What we did this all the time when I was younger." I said, "Yeah, at first it was to keep Hiro from hitting him, but after we broke up I did it because I liked it." Asuka said sweetly, "Asuka why are you in London? I thought you were in Osaka." I asked, "Well for two reasons, one because this is where Jack is from, and two because Hiro found out where I lived and wouldn't leave me alone." She said, "Mommy be careful he's a master." Jack said as she reappeared next to Summer, "(y/n) are you really a master in this year's grail war?" Asuka asked, "Yeah, I... I just wanted siblings to be proud of me." I said, "Oh please don't tell me Hiro's still picking on you." She said, "He is, and things have gotten worse now that he's got Berserker." I said, "(y/n) do you remember the promise I made you?" She asked, "No I'm sorry." I said, "Well it was four years ago so it's understandable." She said, "I promised that if Hiro was still bullying you, and if Tohka didn't do anything about it for at least a year and if I was eighteen or older that I would come back and adopt you. That offer still stands your Aunt Sakura already she would be ok with it if you chose to let me adopt you." She said, I got off her lap and faced her, "I...I'll think about it." I said, "Ok, well let's go get some lunch or did you eat on the plane ride?" She asked, "No I was a bit nervous about what was going to happen." I said, "Aww I'm sorry sweetie I honestly didn't mean to scare you." She said, "It's alright, but I did come here with Rin." I said, "I know, she'll get what's coming to her later, but for now lets get something to eat. I was thinking burgers and chips, how does that sound?" She asked, "Chips?" I asked, "Oh that's right, chips are just french fries sweetie." She said as she got up and held my hand.

"So hows the burger (y/n)?" Asuka asked, "It's good. Aunt Sakura would probably throw a fit if she found out that I was eating this." I said as I took another bite, "So she's still picky about what you eat huh." She said, "Yeah." I said, "Mommy I'm hungry." Jack said, "Jack honey you know the deal." Asuka said, "Ok Mommy." Jack said as she disappeared, "Summer how do you like your food?" I asked, "It's fine." Summer said, "Your mad." I said, "No no, it's just I don't know how I feel about all this that's all sweetie." She said sweetly. "(y/n) do you have a place to stay while your in London? I feel a bit silly for just now asking this." Asuka said, "No, Rin and Summer briefly talked about it on the plain, but I don't like the idea of sharing the same hotel room as her." I said, "LIKE I'D LET YOU! Honestly the nerve of that damn witch, thinking that she has the right to come back into your life like that and expect everything to be fine." She said as she took an angry sip of her soda, "Well looks like you have no choice you'll be staying with me at my place." She said softly.

"(y/n) get ready for bed alright." Asuka said as she put her jacket on, "Wait your leaving?" I said, "Yeah, sorry bud something came up at work. I shouldn't be too terribly long I promise." She said as she ruffled my hair and walked out the door.

Asuka POV

I was halfway down the street when I finally felt comfortable. "So were going to kill her right Mommy?" Jack asked as she rematerialized beside me, "Yes we are honey." I said, "And after she's dead can I eat her heart?" She asked, "If you can find one you may." I said as we walked, suddenly there was an arrow fired at me just barely missing hitting me in the foot. "So you planned on killing me as well." I said, "Yes, now where's my son?" Rin asked, "Safe from the likes of you!" I said, "YOU WANT ME I'M RIGHT HERE!" (y/n) shouted, suddenly there was a gunshot rang out, "(Y/N) WHAT ARE YOU DOING HERE?! GO HOME NOW!" I yelled, "NO I'M NOT THAT TERRIFIED LITTLE KID YOU REMEMBER! I'VE GOT A FEW NEW TRICKS NOW!" He yelled as he jumped and fired his gun propelling himself up onto the same roof as Rin. "SUMMER KEEP ARCHER BUSY!" He shouted, "Jack help Summer deal with Archer." I said, Jack nodded and ran off to help.

(y/n) POV 

"Trace on." I said and a sword formed in my hand, I tossed it to her, "Oh what's this?" Rin said, "There's no honor in defeating an unarmed opponent." I said, "So I get a sword while you have a gun, that hardly seems fair honey." She said, I glared and switched my gun to it's scythe mode.

"Impressive sweetie, but can you use it?" She said, I laughed, "Oh mother do you know the downside of being eight and wielding a  high powered scythe pistol?" I asked, "You just called me mother." She said happily, "It's the recoil. It's so intense that I can use it to propel myself or create devastating power attacks." I said as I ran at her dragging my blade along the roof.
