Something Blue
"Percy's signal came a little late."
Sally kept waiting. She would wait her whole life if she had to. "Something blue," Percy had promised. But there wasn't a speck of blue anywhere, now. There was only the sickening red shade of blood, the gray dust of destruction, the golden glint of swords.
Paul appeared by her side. "Sally?" he asked gently, wrapping an arm around her shoulders. "We have to get to a safe place—"
"No," Sally whispered. "Percy—he has to be somewhere—Olympus, or—or—"
"He'll be fine," Paul assured her. "I know he is."
Sally scarcely panicked in her whole life. She'd learned to know how to keep calm whenever she or her son were in danger (no matter how much she would fuss afterwards)—you had to be like that when you're in a relationship with Poseidon.
But now she barely heard him. She looked around her, searching fearfully for a clue, a sign—the fighting had to have stopped by now. Something—anything blue—blue lights, blue cars, even blue monsters, damn it—
She looked at the Empire State Building in desperation—and just that moment, the top lit up in blue, brighter than she'd ever seen.
"Sally," Paul said in amazement. "Sally, that's got to be Percy's sign, it's—"
"Something blue," Sally said, tears of joy and relief trailing down her cheeks. "Thank you, Percy."
AN: This is perhaps not very accurate (I didn't research the exact happenings in the books again, to my shame) and horribly short, but please take pity on me. Constructive criticism is generally preferable to flames or, God forbid, false praise.
