THALIA
"Please Artemis" Thalia begged, "just for one night." Ever since the iris message her brother had sent her 3 days ago, telling her of Jason's plans for christmas, Thalia had made it her mission to get Artemis to cooperate.
"No, Thalia" The goddess told her, "And there's nothing you can say to make me change my mind."
...
JASON
Jason sat in cabin one, waiting for his sister to iris message him, it had been three days since he had told Thalia of his plans to give Nico a christmas. Since then, he had got Piper, Percy, Annabeth, Hazel, Frank, Leo, and Will in on the plan, all of them were willing to help him.
The mirror opposite him glowed. Jason grabbed a drachma from his pocket and tossed it into the rainbow that had been created. Thalia stood there on the other side.
"I'm gonna need help," she told him "Artemis isn't keen on having five boys riding her chariot."
It didn't take him long to realise who to send, if anyone could convince Artemis to give up her chariot to five boys, it was Piper.

PIPER
When Jason came running towards her while she and Annabeth were training, she knew it was going to be about his plans for christmas. It was the twentieth of December, they had only four days left until Christmas eve and they still hadn't had the okay from Thalia.
"Hey Beauty Queen" he said once he got close enough to her for her to hear him.
"Why hello Sparky" she replied. Jason grinned at her, the lopsided kind he knew she liked. He got close enough and hugged her, whispering in her ear as he did.
"Thalia needs your help." She pulled away. What had happened to Thalia? Jasons sister was one of the scariest people she knew, not counting Annabeth, and why would the daughter of Zeus need her help?
"She's having trouble convincing Artemis to lend us the moon chariot."

THALIA
"Come on, it's just one night," Thalia pleaded, "I will be there and I swear on the styx that I won't let any boys ruin your chariot." As she was saying this she peered over the goddesses shoulder, hoping to see Piper McLean, the saviour her brother had promised.
"No Thalia, how many times do I have to tell you, now get inside the tent, you know Pheobe's injured so she should be your priority." Artemis was right, a hunter had been harmed under her command, Thalia had a duty of care and after the bite Pheobe had got from that hellhound her lieutenant was her top priority. Thalia went inside and started dressing Pheobes wounds, about ten minutes into it she heard voices outside.
"Lady Artemis" definitely Piper, the voice had the unmistakable whispering lilt of charmspeak, "think about it, you've never enjoyed your burden of driving the moon chariot. You want to be on the ground every night, fighting the creatures of the dark side by side with your hunters. Let me give you one night, one night to spend with you loyal followers. What do you say?"
"Just one night?" Artemis asked.
"Just one night" Piper replied, still filling her voice with charmspeak
