Sakura blinked.
So, for that matter, did the friends she was eating lunch with. However many admirers her sweet-hearted disposition might have won, as far as they knew, the only people who knew her well enough to actually call her cell were all already present.
"Well?" one urged after the first moment's startlement. "Answer it!"
So she did. "Moshi moshi?"
"Master," said Caster's voice. "There is another Servant on the campus, besides myself and Rider. Your sister plans to confront him after the school empties for the night, and suggests that you go home via-"
"No," she cut him off. "We'll stay." She didn't have any particular interest in risking herself, and knew that she didn't have the skills to really contribute, but Caster had also made it quite clear that he had no intention of leaving her unprotected. She'd need to be somewhere safe before he'd leave her, and with the Grail War underway, 'safe' meant under the protection of a Servant. "You can't help if you're not here."
"Understood. I'll start preparing, then. Goodbye, Master."
Oh, yes. Westerners did that at the end of phone calls, didn't they. "...Goodbye," she said, and killed the connection.
Then she looked up and started to sweat. Her friends were watching so intensely! "Who," demanded several, not quite in unison, "was that?!"
Struck by a sudden wicked impulse, she smiled and returned to her lunch, and refused to answer.

It started very suddenly. One moment Rin was leaning against the chain-link fencing that ringed the school's roof, the next, she was grinding her cheek into the grit of its concrete. A moment later, when the brilliant bolt of light blasted a meter-wide hole through the facade she had been standing behind, she realized why Rider had knocked her down.
"An Archer?" she asked herself as she scrambled to her feet.
"No," the Servant answered. "He's mounted."
The other Rider, then. She glanced over her shoulder at her sister and the green-cloaked Servant looming behind her. "You knew?" she asked him.
"Pretty much," he shrugged. "His name's Temujin, I don't think he's been in a Grail War before. His defensive power is low and his charge isn't anything to write home about, but he's fast even for a Rider and," he gestured vaguely at the hole in the roof, "he can work at a distance."
"Can you slow him down?" Rider asked. "Pin him in place for my charge?"
Rin stepped forwards for a look at their opponent, since he seemed to be waiting for a reaction. Details were mostly lost in the distance, but the Servant was there on a shaggy-looking pony, and his Master stood beside him. She didn't need to see Caster to know he was blushing, though - he wasn't very talkative, on the whole, but that didn't make his crush on his counterpart any less obvious. "Yes. But it will cause the same problems for you."
"But I," she answered, "will not be alone."
He smiled. "As you wish, then. Tohsaka-sama, you can deal with his Master?"
"Hai."
Caster brought one hand up and fanned a sheaf of ofuda out, like a magician doing a card trick. "Then let's begin."
Yes, he's got a thing for her, even at his age. Wouldn't you?
Ja, -n
