Child: Mommy, how did you and daddy fall in love?
Rin: Well, we went through a lot of things together and his personality was so honest and true that I just couldn't help falling for him. And besides, it is so much fun teasing your father that I just couldn't let that go.
Child: How about you daddy?
Shirou: Well, your mother was the perfect school idol so it was only natural for me to lik her. *(Rin grins and nods her head in agreement in the background)
Child: Really?! Mommy was pretty even back then?
Shirou: Of course she was! *(Rin begins to glow with pride)
Rin: Shirou! You're such a smooth talker *(Shirou cuts her off)
Shirou: But then as I got to know her better I realized she was a complete fraud. She was lazy, a total mess in the morning, really bossy, tended to mess things up at the critical moment and kind of jealous to boot. In fact for a while, I thought it might be nice to go back in time where I was totally ignorant of her true nature!
Aha ha ha ha ha!
*(Rin begins to twitch)
Rin: Emiya-kun~~ You're so honest...
Shirou: (*In a panic and backpedaling) Uwaaaaaaaa!
Bu bu bu but you se se see, the more I found out about her true character the more I fell in love with her!
*(Child runs for cover as her IMMINENT DOOM sensors activate)
*(Rin steps forward with a smile on her face and fist upraised)
Rin: Emiya-kun, it seems to me that you are already quite ignorant. However you haven't traveled back in time yet. Allow me to fix that for you!
*(After numerous blows to the head, Shirou actually does think he's back in time)
Rin: Hmph! Come child, I will tell you EXACTLY what your father was like when I first met him!
Child: Wow Mommy! You Pwned Daddy!
Rin: That's right! I do Pwn him don't I! Oh ho ho ho!
Shirou: I have no regrets. This is the only path.
