Prompt from Sonofthetrigod: Nico vs Percy Santa Claus battle; unexpected ninja attack by none other than...
"Santa Claus is, in no way, shape, or form, real." Nico's voice is stern.
"Explain Saint Nicolas, then!" Percy's voice was slightly high-pitched, and his tone suggested that he was struggling for debate material.
"He lived like four hundred years ago, and was the creation of the myth–"
"Yeah! Myth!"
"No, like a fairy-tale."
"Well people could argue that myths are derived from fairy-tales."
A snort. "Yeah, you could argue that, but you'd be wrong."
"No, you're wrong, Hell-Boy."
Silence, then Nico bursts out laughing. "Have you been taking nickname lessons from Thalia or something?" he says once he regains his breath.
"Maybe," Percy grumbles. After a few beats, he says, "Did you have to record this?"
Smugly, Nico replies, "Yes. I'm going to record the aftermath, too, plus people's reactions when they hear I won yet ano–" He's cut off by a sudden crash, like something falling through plaster, and a high-pitched "Hii-Ya!"– There's a high-pitched shriek, and Nico yells, "What? You don't– are you in costume?!"
A low, gruff voice replies "No," and then Nico's yell accompanies Percy's: "Santa Claus is attacking us! Help!"
"I though he didn't exist!" Percy shrieked back, and there were loud thunk-sounds and yelps.
"You're seriously still going to fight me on this as we're being attacked?!"
"Just say I'm right!"
"He was right," the gruff voice replied, and then with a sharp crack and a thud, as if the camera fell on concrete, and a few seconds passed before a tentative whisper sounded out, a bit off from the camera: "Is he gone?"
"I guess," another whisper replied, closer to the camera. "Where did he come from?"
"And where did he go?"
"I wonder if his name is–"
"If you say 'Cotton-Eyed-Joe, so help me Zues, I will punch you in the throat."
