(y/n) POV

"Tohka I need to ask you something." I said, "Sure ask me anything you want." Tohka said sweetly, "Are you positive that Rin is really my mother?" I asked, "What are you talking about of course she is!" She said, "Just think about it why would a woman who abandoned her children just come back one day and actively try to get ONE back?" I said, "She wouldn't, alright say for a second I actually thought you had a point, how would you go about finding out exactly who your real mother is?" She asked, "Simple I'll do some research." I said, "Thank you Tohka, I love you." I said as I hugged her, "I love you too (y/n), but don't do anything stupid!" She said, "What like take Archer from Rin in an act of revenge... oh wait I already did that." I said, "YOU DID WHAT!" She yelled, "HOW DID YOU MANAGE TO GET OUT ALIVE?!" She yelled, "Well it's not like anyone got hurt, all we did was sit down and have a nice chat." I said as I walked away.

"I'll never find what I'm looking for!" I said as I put my head down onto the table, "I thought the public library would be a good place to look, but I guess I was wrong." I said sadly, "Do you need some help little boy?" A woman asked, "Yes, I'm trying to find out who my mother is, but I'm not having much luck." I said, "I can help with that! All I'll need is your name." She said as she got on a computer, "Ok it's (y/n) (m/n) Emiya." I said, "Wait your father wouldn't happen to be Shirou Emiya would he?" She asked, "Yes." I said, "I KNEW IT!" She yelled, "I can tell you exactly who your mother is, I was there when you were conceived after all." She said, "Wait who are you?!" I asked, "You can just call me Auntie Fujimura!" She said happily, "I was kinda like your fathers older sister." She said calmly.

I called Aunt Sakura and asked her about Fujimura. "Well now that you know that you can trust me, how about we go get some lunch." Auntie Fujimura said, I nodded.

"So tell me why are you looking for your mother? Don't you live with her since your father died?" Auntie Fujimura asked, "No I live with aunt Sakura, but I recently heard something that's been making me think." I said, "What did you hear?" She asked, "Well apparently when I was a baby Dad had my blood tested and well my DNA showed positive for both the DNA of Rin Tosaka and Sakura Matou. So I'm really not sure who my mother really is." I said, "It's Sakura." She said, "Wait what?" I asked, "Sakura is your mother, I was there when they did it." She said, "Ok then tell me does Sakura treat you more like a nephew or does she treat you like a son?" She asked, "A...A son, but she raised me and my siblings for the past eight years." I said, "Yes, but she didn't have to after Shirou died." She said, "B...but that means that I went behind her back and got adopted." I said in shock, "Well it's not your fault you didn't know kiddo." She said sweetly.

When I got home I went into the library and opened one of Aunt Sakura's scrapbooks. After looking at it for a bit I ran to go find her.

"(y/n) sweetheart what's the matter?" Aunt Sakura asked as I ran into her room, "I'M SORRY!" I cried as I hugged her, "Shh its ok sweetie." She said as she rubbed the back of my head, "So you finally remembered then." She said sweetly, "I'm so sorry Mommy!" I cried, "Shhh it's ok sweetie, it's ok. It's not your fault, I rewrote several people's memories. I changed it so that they remembered Rin giving birth to you, it was your fathers idea." She said, "B...But you could have told me and it wouldn't have changed anything!" I said, "I know, I know, I didn't know how it would affect you so I decided to keep the truth from you I'm so sorry sweetie." She said sweetly.
