Prompt: "Shirou Emiya summons Rin (Ereshkigal) after she had saved him. Naturally, this makes EMIYA a bit of a third wheel as Ereshkigal's mellow and shyness (FGO personality from what I can see) allows her to not be so Tsundere. Shirou, having already liked Rin and Rin being infatuated by the Hero kid, decides that maybe they can have a date.

It'll be quite interesting for Rin to explain her Blonde hair and red eyes should she meet Sakura, that's for sure." — myfunvideos, answered by nd7878

"What have you done to my Master?" Archer growled under his breath. Not in malice, though, or anger. He definitely wasn't ready to fight (whoever possessed Rin, anyways).

He watched Rin-but-actually-Lancer spin around and smile at trees, reach to pet any animals she could find, and, finally, duck around a wall with a panicked expression.

"I told you to keep watch, Archer!" The blonde Rin poked her head around the corner, eyes trailing to a-

Oh no.

'Please, Alaya. You can have my eternal soul for as long as you need me, just… don't do this.'

Archer's archer eyes picked up a very familiar head of red hair across the courtyard. Three command seals shown on his hands, almost-but-not quite matching those on Lancer's own hand.

And thus he was reminded that, even if they were separated by a degree, Shirou was technically his Master. His grand-Master, if you would.

Archer would not. He already had to listen to Lancer-Goddess-Rin gush about how her brave Master jumped to save her like a true hero, and how she was so ashamed that she couldn't look him in the eyes anymore.

It made him want to puke.

But Lancer wasn't trying to hide, not really, and her yellows and reds stood out. Even Shirou, with his not archer-eyes, could find her.

"Rin- I mean, Ereshkigal! There you are!" he called, running up to her. She turned beat red at his approach.

"A-ah, Shirou! You corrected yourself, so I'll let the 'Rin' part slide, as a benevolent goddess."

He smiled. Archer gagged. Who was this so-called goddess who neutered all of what made Rin great?

"Well, you ran out last night, and I was worried you might be in danger. I spent all night searching for you."

Ereshkigal's face was indistinguishable from her maroon cloak. "T-that was unnecessary, I can take care of myself, but… thank you. This goddess appreciates it."

"Of course!" Shirou beamed. "If you want to come back, I saved the dinner from last night, if you'd like some."

"I'll accept your offering!"

Archer didn't follow them. He didn't feel like it. This was wrong and he would have no part in it. He summoned a blade to his hand, pointing it at Shirou's back.

'Not today. Hold out just a little bit longer, EMIYA. Just. A. Little. Longer.'
