A/N: So this is a quick funny drabble because it sounded really funny in my head. One of the things I loved about Blood of Olympus was Annabeth's and Piper's friendship. Also, cookiekhaleesi's drawings made me think of these two as having a friendly rivalry in which they are always trying to out-do each other and poke fun at each other. Also, uh, percabeth smut implied, I suppose.

Touché

Annabeth knew Piper was up to something the moment she approached her worktable in ceramics class. She had the same wicked gleam in her eyes as the day she'd charmspoken a conceited son of Hebe into being a model for her little half-sisters' makeover games. She'd sent her a questioning look, but was met with a fake innocent smile as her friend plopped down beside her and started working the clay into some kind of sculpture. Annabeth went back to her vase and left her to her own devices. She wasn't sure she even wanted to know.

A minute into the shared silence Piper called, "So. I have a question."

"Shoot."

"Are our cabins considered our parents' temples?"

Annabeth pondered on that. "Suppose. You could be shot down by a lightning bolt if you trespassed. Barging into another cabin without permission is very disrespectful, so I guess it could be considered a temple of sorts," she reasoned.

Piper hummed noncommittally and didn't comment further.

A few minutes later she spoke up, "Remind me again. Athena started hating Poseidon because of the whole Medusa thing, right?"

Annabeth turned to her, brows furrowed and eyes narrowed in suspicion. "Yes. There was a rivalry before, of course, but it really turned ugly when he desecrated her temple."

"I see."

She waited a bit, expecting Piper to pop another question in the next seconds, but she seemed concentrated on her clay whatever-it-was, so Annabeth let it drop.

Two minutes later Piper blurted cheerfully, "So do you think your mom will call it even now that you desecrate Poseidon's temple every week?"

Annabeth nearly choked on air, the hand shaping the vase smashed through the clay and turned it into a blob. Piper was looking at her with a shit-eating grin that would make Connor Stoll's look bashful.

She did her best to look as dignified as possible. She eased her foot off the pedal to stop the spinning and rubbed her hands off the excess clay, while thinking of a good comeback. How had Piper even seen her though? She wore her cap. Although, she could have spotted her on one of those days she was in a hurry. But Cabin 10 was all the way across the courtyard, she couldn't have seen that far. Unless…

Annabeth turned back to her smashed vase and re-started the spinning, throwing over her shoulder, "And I suppose you saw me sneak into Cabin 3 from the roof of Cabin 1?"

Piper's expression turned solemn. "Ah. Touché."

They stared at each other.

"I won't tell if you don't."

They shook on it.

"Still… Pretty sure that's not what your mom gave you an invisibility cap for."

"Get lost, McLean."
