"My pleasure," he said softly. "Call me Caster."
"'Tatarusha'..." she whispered, trying to place why the word would be familiar, and then she translated it in her head and aborted an attempt at sitting up when the pain surged back to the fore. "...the War."

But that was wrong. She shouldn't be the one. "But I'm the younger child..."
He snorted. "And that means what to me? The one speaking the words doesn't matter - it's the power that does the trick, and no matter how those two wastes of flesh tried to hide it, that was yours." He turned his head slightly, and wouldn't look at her. "Besides, you deserve my service. They never could, and I'm a mage myself - I'm not so easy to compel."
Not so easy to... Her blood ran cold. He had defied her brother - defied her grandfather - and then come here, where they'd - where he'd... "You... have to go!" she hissed. "They'll come... and..."
"I won't let them lay a finger on you!" he retorted.
Damn, but Sakura's hard to write.
ETA: Griever, I had a thought - once Berserker gets whacked (which'll probably happen earlier than in canon), Ilya's going to be on the lookout for a new Servant. If 'Longinus' had already lost his boss at that point, we'd be saved the trouble of developing at least one troublesome original character...
