Sakura
Sakura looked back and forth frantically between Rin and Shirou.
“Sakura, what's wrong? And, Rin, Sakura is only two years younger than me, and she's my wife”, he said, before his pain-addled brain did a double-take.
"Wait, Rin, why are you even here? What is going on?" he continued, thoroughly confused at the situation.
“S-Senpai, that’s what we should be asking you!” Sakura started. “What are you doing here?” Sakura avoided eye contact, blushing profusely. As Rider spoke and her gaze wandered, she noticed Rin’s clothing sprawled on the floor, covered in blood. Sakura quickly looked up at Rin, and noticed she was clad only in a towel. She acted quickly, her shadow coming into existence and forming a blindfold over Shirou.
“That’s right, we’re not married yet! You haven’t even proposed to me!” Sakura began to berate him. “Wait--” Sakura looked closely at him, and saw a much older man than the one she had left upstairs. “Do you have your own Sakura?” She asked hesitantly.
