Shirou and Rider
Shirou waited patiently for Rin to complete the scrying spell. However, before she could do so, there was a sudden crash from the kitchen, followed quickly by Sakura's voice, calling for Rin to come and help.
Shirou sighed as Rin handed back the wedding ring and left the room. He and Rider stood around waiting for some time, unsure what to do next, until they heard the ground underneath them echoing with heavy footsteps.
What? thought Shirou.
Rider, on the other hand, had a pretty good idea what was happening, and smiled. Whilst Vanguard was not necessarily entirely trustworthy, he seemed to sincerely wish to protect Sakura and, as such, Rider was glad that he was, seemingly, back in one piece.
Rider's suspicions were confirmed when she heard Vanguard's booming voice come from behind her.
"Greetings", he said.
Noticing Shirou, he spoke up once more.
"Is that... Emiya Shirou?" he said.
Shirou looked around with a mixture of surprise and confusion. These emotions were only increased when he found himself staring at an eight-foot tall, talking suit of armour. Who, apparently, knew him, somehow.
"Yes?" he said, quizically. "Who are you, and how do you know me?"
