Rin
Rin watched as Sakura leaned against Archer as naturally as she would have leaned against Shirou. The sight caused her stomach to twist and ice to form in her chest. She clasped her hands behind her back so Sakura and Archer wouldn't see her resisting the urge to clench her fists, as she was already resisting the urge to grit her teeth.
Then Sakura's words registered.
Sakura had another Servant.
Not just any Servant, but the famous Joan of Arc, the holy maiden, at her beck and call.
Archer made some comment about Servants falling out of the sky here, but Rin barely registered it. More ice was forming in her chest. Archer asking Sakura what she wanted to make for dinner wasn't doing anything to make it go away.
"Don't worry about setting me a place. I doubt I'm going to be back for dinner," Rin said with as much cheer as she could muster. "So you two have fun."
She wasn't going to bemoan the "fairness" of the situation. Nothing was fair after all, but she wasn't going to take it. She had lost the one thing that really meant anything to her. She had no lover to share her life or bed with, and didn't really have any close friends. Being an Asian at the Clocktower pretty much made her a social leper, and she knew no matter how hard she worked, unless she became a True Magician, no one would acknowledge her for anything other than potential breeding stock and to get their hands on her lands.
Closest thing she had to a friend there was Luvia, but half of the time they just beat the shit out of each other.
The one thing she had, the one thing that made her happy without any bittersweet tang, was her work and her research. To pursue the Second. And all of that was gone, locked in another world now forever beyond her reach.
Her eyes stinging, Rin began to turn to leave before Sakura could stick one of those familiars on her or before anyone would see her cry.
