This one takes place in between the lines on pages 172-173 of The Last Olympian. I kinda manipulated the scene a bit.

Disclaimer: I own nothing.

"Thank the gods," Annabeth said. "But if we don't blockade the rivers from those boats, guarding the bridges and tunnels will be pointless."

"You're right," I said.

And she was right. I- we needed to take care of that problem immediately. But first-

"We need a hot ride, something to get around town with," I said. The other campers were busy preparing for battle. Last minute things, like fixing their armor and saying farewell and praying to whatever gods would listen. Unlikely that their prayers would be answered, but you couldn't not pray. They had to try. I looked around, searching for something we could borrow. Something small enough to maneuver around the cars and fast enough to get us there quickly. I had to stop the water invasion.

"Over here, Seaweed Brain." Good old Annabeth. She found a shiny red Vespa parked in front of a car a few yards away. We gently removed the woman driver, laying her to rest on the comfy sidewalk.

"Hey, how come you get to take something and not us?" I heard Connor Stoll call to me from the crowd. He sounded like a little kid whining about getting a new toy.

Annabeth rolled her eyes. "We're just borrowing this to save the sake of humanity and all things dear to you. Any other questions?"

I detached the helmet from the woman. It was bright pink, with purple and orange flowers painted all over it. There was no contest on who was going to wear it.

"Annabeth," I called her over. As soon as she saw the helmet she started shaking her head.

"No way," she rolled her eyes.

"Come on. Please, for me? Just for a second."

She sighed and somehow didn't resist, which was a miracle. I set the helmet down on her blonde curls, patting the top.

"I don't need a helmet," she argued.

She tilted her head back though, and I fastened the straps under her chin. She had a pretty nice neck, which was a weird thought. My hands were more steady than I thought they would be. My fingertips grazed the skin exposed there. The inside of my stomach was tumbling and turning like a leaf in the wind.

"Maybe I just want to protect your pretty head," I said matter of factly. She didn't comment on that, but she didn't resist either. It was a good thought.

I noticed it was completely silent. I looked up, and noticed most of the demigods staring at us, a few snickering. I decided to ignore them, turning my embarrased face back to the Vespa. I begin to slide on when I feel Annabeth grab my arm.

"What?"

"I want to drive."

"Annabeth," I started, but she stopped me.

"Come on. I'm a better driver than you, my dad owns one just like this. I know how to work it," she bickered.

Partly because I couldn't deny her much and partly because the world was ending, I decided to let her drive. She slid in the front, and I got on behind her, holding her waist.

I looked at the campers, all of them grim and determined. I tried not to feel like this was the last time I'd ever see them all together.

"You're the greatest heroes of this millennium," I told them. "It doesn't matter how many monsters come at you. Fight bravely and we will win." I raised Riptide and shouted, "FOR OLYMPUS!"

I must've looked pretty ridiculous, giving a speech and words of encouragement from the back of a bright red scooter. I had to lean backwards so I could lift my sword and her flowery helmet was hitting my forehead. But they took the call, and we defended our turf.

Later in the midst of the battle, I could see Annabeth in the distance, still sporting the pink helmet with the purple and orange flowers on it. And the sight brought a real smile to my face.
