A/N: So I was going through all my fanfic files on my laptop earlier today and I discovered this little fanfic collecting virtual dust. So I cleaned it off and fixed it up and decided to post it! Another nice little treat for my subscribers who want more PJO :D This is a dialogue fic (which means dialogue only-no extra words in between; good practice for showing vs. telling, if you know what I mean). In case you can't tell (I would be extremely worried about you if you couldn't), it's Percy and Annabeth talking. Enjoy!

Disclaimer: If you honestly think that I own PJO...well...you might need to get your head checked...again ;)

"Hey, Annabeth."

"What's up, Percy?"

"Well, I've been thinking…"

"Oh gods. It's the end of the world. Percy has been thinking!"

"Shut up! I can have good ideas!"

"Maybe sometimes. But you were saying?"

"Uh…I was thinking…"

"Yes, we got that far."

"Gods, Annabeth! Stop interrupting! What I'm trying to say is that maybe you should stop…you know…calling me 'Seaweed Brain.'"

"That's what you've been thinking about?"

"Hey, stop smiling! It's not funny."

"Well, it's funny to me."

"Fine, be that way. But…aren't we a little too…you know, old for name-calling and that sort of stuff?"

"Heh. You're just sore because you can't think of a good comeback for it, Seaweed Brain."

"What? That's—that's—"

"Totally true and you know it."

"…Yeah…but still. Other people are starting to say it too. Just the other day some naiad came up to me and asked, 'Are you the one with the brain of seaweed?'"

"Oh gods. Really?"

"Stop laughing—it's not funny! Soon the whole camp will be calling me…that."

"Heehee. Ahem. Sorry. I guess we do have a problem."

"It does matter—wait. Did you just…"

"Yes, I agreed with you."

"Wow. I thought my ears were deceiving me, but it's true—the great daughter of Athena has finally lowered her intellectual level to that of humble seaweed-brained little ol' me."

"Percy!"

"Ow! That hurt!"

"It was supposed to. But I'm surprised—you actually used big words like 'deceiving' and 'intellectual.' And I'll give you points for sticking 'humble' in there as well. I must be rubbing off on you."

"Hmph. I told you I'm not a seaweed brain."

"No, you're not a seaweed brain. You're my Seaweed Brain."

"…Huh?"

"Never mind. Anyway, how about I just call you that when no one else is around to hear it? Then everyone's happy."

"Fine, I guess…hold on, I'm not happy! You'd still be—oh, forget it. You're never gonna let that dreaded nickname go, are you?"

"Not for all the hippocampi in the world. But let's face it—you don't really mind that much when I say it, do you?"

"I…um…well…"

"Heh. You're blushing…"

"Am not! It's just warm in here, that's all."

"…You're funny, Seaweed Brain."

A/N: So, just a simple conversation and a tiny, miniscule bit of fluff. I actually posted a fic similar to this the other day, but I'd totally forgotten about this one then. So...just another take on the whole Seaweed Brian nickname thing :) Thanks for reading!
