“But I suppose if you're friends of Magnus's ..." He went completely still. His runes faded. Then he leaped out of my hand and flew towards Annabeth, his blade twitching as if he was stiffing the air. "Where is she? Where are you hiding the babe?"
Annabeth backed towards the rail. "Whoa, there, sword. Personal space?"
"Jack, behave," Alex said. "What are you doing?"
"She's around here somewhere," Jack insisted. He flew to Percy. "Aha! What's in your pocket, sea boy?"
"Excuse me?" Percy looked a bit nervous about the magical sword hovering at his waistline.
Alex lowered his Ray-Bans. "Okay, now I'm curious. What do you have in your pocket, Percy? Enquiring swords want to know."
Percy pulled a plain-looking ballpoint pen from his jeans. "You mean this?"
"BAM!" Jack said. "Who is this vision of loveliness?"
"Jack," I said. "It's a pen."
"No, it's not! Show me! Show me!"
"Uh ... sure." Percy uncapped the pen.
Immediately it transformed into a three-foot-long sword with a leaf-shaped blade of glowing bronze.. Compared to Jack, the weapon looked delicate, almost petite, but from the way Percy wielded it I had no doubt he'd be able to hold his own on the battlefields of Valhalla with that thing.
Jack turned his point towards me, his runes flashing burgundy. "See Magnus? I told you it wasn't stupid to carry a sword disguised as a pen!"
"Jack, I never said that!" I protested. "You did.”

“Annabeth frowned. "Percy's sword is a she?"
Jack laughed. "Well, duh."
Percy studied Riptide, though I could've told him from experience it was almost impossible to tell a sword's gender by looking at it.
"I don't know," he said. "Are you sure -?"
"Percy," said Alex. "Respect the gender."
"Okay, fine," he said. "It's just kinda strange that I never knew."
"On the other hand," Annabeth said, "you didn't know the pen could write until last year."
"That's low, Wise Girl.”

“Stop that, I told my brain.
Also, the wedding is tomorrow, said my brain.
Get out of my head.
My brain refused to get out of my head. Inconsiderate brain.”
