Leo and Conner grinned at each other. They'd been planning this prank for almost a week now and today was the day that they either made it or broke it.
Leo had rigged up the cameras. Conner had brought the fake spiders and cobwebs. It wasn't hard to sneak both into the Athena cabin, they just had to wait for everyone to head to the amphitheater. They'd been coming a little late each night, so as not to arouse suspicion. Leo used the excuse of working late in Bunker Nine and Conner had been busy Iris-Messaging boys grinned at each other and highlighted before speeding to the Amphitheater, with Leo going in firs and Conner 5 minutes later, just as the next song was starting. In the darkness, no one really noticed much.
Mission S.A. part one was a they just had to wait until the campfire time was over.

That night, one terrified Annabeth Chase finally figured out that the whole thing was a prank.
Around 1 in the morning, four figures were spotted by the harpies sneaking around camp lugging two large sacks.
By coincidence that same night, the head counselors of Hephaestus and Hermes disappeared under mysterious circumstances.

The next morning around 6, loud yelling/cussing woke many of the camp's residents up. Following the sounds of shouting, several of the satyrs found Conner and Leo tied up inside a large sturdy net, hanging over the camp lake. Both wore only pajamas and Leo's toolbelt had mysteriously disappeared.
The campers stared at the sight, confused, before someone-or rather, two someones-made their way to the front of the crowd. Percy and Annabeth.
And Annabeth had a camera in her hands.
Percy cut the net open with his sword and the duo fell into the lake with a loud Splash! He, however, didn't bother pulling them out, which to many who knew him seemed very much unlike Percy's usual easygoing nature.
Annabeth then led everyone to the Big House, where a projector was already set up. Pushing a few buttons, she soon had it up and running.
And it became obvious what had happened the night before. The film (or video, whichever you want to call it for it was a mix of both) started by showing footage from the previous night, when Annabeth had pulled back the covers on her bed to find plastic a muffled scream, she'd turned around and seen the camera. Then everything went black for second. When the footage returned, it had changed to pictures instead of a video. The camera was facing the Hermes cabin, where the unmistakable figures of Jason and Nico appeared dragging out an unconscious Conner. The next image showed Percy and Annabeth with Leo. The next few slides were ones showing the pranksters tied up in the net over the lake and Annabeth hiding Leo's toolbelt under his bed, before the credits rolled. By then everyone in camp, even the two groups of pranksters, had started laughing. Nico smiled one of his rare smiles and Jason and Percy were on the ground roaring. "And that," Malcoln, one of Annabeth's siblings said, "is why you should never prank the Athena Cabin, especially when their head counselor is friend with sons of the Big Three."
