"I," Annabeth announced, "am officially hating ADHD."

"Uh," Percy said, looking up. "Random."

"Hence the ADHD," she mumbled darkly, tapping her pencil against her leg. "Why are you purple? Are you supposed to be purple?"

Percy gave her a weird, decidedly violet look. "Um, no, I'm not supposed to be purple."

"Well, you are!" She yelled, exasperated. Percy sat up and stared at her. They were lying in bed at ten pm on a random Thursday, three weeks since the spurt of fierce pranking. That had been in early May-now it was almost June, they had finally graduated, and they were going to get married the next month. The wedding, which had been hovering hazily in the near future, was now suddenly upon them after Sally had put her foot down and insisted they set a date. Everything had fallen into place and here they were.

"Purple," Annabeth mumbled, distracted. She was fully dressed, a clipboard and pencil in hand, but her hair was in a bun hanging messily off the side of her head and she was totally agitated. Percy was sitting next to her, under the covers, trying to nail down the guest list-which was usually her job. Annabeth had tackled the wedding with a vengeance, flanked by her trio of best friends and an enthusiastic excitement. Tonight was a different matter.

"Annabeth, how much cold medicine did you take?" Percy asked, incredulously.

"Three," she said vaguely.

"Three what?"

"Big Three," she exclaimed. "Number of demigods safe to take on a quest. Sign of . Third. Aliquot sum of four. Number of sides in a triangle. Fourth Fibonacci sequence."

"Okay," Percy said nervously, swinging out of bed, "how much did you take?"

"What I usually take," she said indignantly. "Two tablets of Xanathin and a glass of water."

Percy frowned. That was what she normally took. Xanathin was demigod safe-it wasn't supposed to have any weird side effects for them (unlike Tylenol, which was another story), and it never had before. So why was Annabeth acting crazy?

Percy stood over her, examining her. Her cheeks were flushed and she looked like she'd gotten some sun-she practically glowed. She'd been radiating pre-wedding nerves lately, but they were both happy. He'd never seen her like this.

She flung her arms wide. "Barney!" she cried ecstatically.

"What in Hades-"

She jumped up excitedly. "Red and blue make purple," she exclaimed eagerly. "Purple makes Barney!"

Percy was completely bewildered. She'd been feeling under the weather lately, had taken meds sometime earlier. He'd come home from a night with the guys to find her sitting on top of the covers in her current state, working furiously on what he'd assumed were wedding plans. It turned out to be mad scribbles in Ancient Greek, the kind of simple recitations she'd taught him with years before. Now he was really concerned.

"Annabeth, are you okay?" He asked anxiously, putting his hands on her shoulders. She nodded good-naturedly. "How many fingers am I holding up?" He asked, holding up four.

"Four," she said indignantly.

"And my full name is?"

"Perseus."

"And your dad lives in?"

"San Francisco. Percy, you need a haircut," she exclaimed. "Let me do it." She dashed away to the dresser and pulled out a pair of kid's scissors. She looked up at him so innocently he almost laughed. She seemed to be pretty sound, mentally-just really hyper, maybe a little disoriented.

"No thanks, Wise Girl," he said, smiling a little, but hoping the meds wore off soon. It was weird to see her like this.

"FRODO!" she yelled suddenly, and bolted out of the room and into the hall, flicking on light switches as she went. "THEY'RE TAKING THE HOBBITS TO ISENGARD!"

"What?" Percy cried, chasing after her. Cancel his last. "Annabeth, what-"

He rounded the corner. She stood on the couch, waving around her copy of The Two Towers. "Tolkien," she said wildly, "should've been made a god!"

"The god of what?" he asked, starting to search for the pill bottle. Anything to keep her talking.

"Middle Earth." She dashed over to him and grinned at him over the counter. "You're very nice looking."

He grinned at that; she'd yet to tell a lie under the influence of what was probably a weird batch of Xanathin. She was herself, but-different. "Wise Girl, where'd you put the meds?"

"Here," she said promptly, opening the cereal cupboard. He decided not to comment on that. He took down the bottle and tried to make sense of the tiny words.

"Fasting affects-past-last! Lasting effects," he read, mumbling. He squinted. "Four hours. Annabeth, when did you take this?" He looked up. She was busily unraveling the throw blanket tossed over the couch. "Seven," she said, happily. It was already nearly eleven.

"Good news," he announced. "This should wear off any time now."

"Spring," she said randomly. "When a young telkhine's fancy turns to love."

"Ookay," he said, alarmed. "That's great. How about you go to bed, maybe sleep this off?"

"Can't sleep," she said, suddenly irritated. What was with the mood swings? Was that a possible side effect? He went back to trying to decipher the lettering on the bottle.

"How come? Nightmares?"

"No," she sighed, flopping back on the couch, dropping the strands of knit blanket.

He didn't ask. "Here we go, Wise Girl. Side effects."

Annabeth started, then looked at the loose yarn in her lap. "Seaweed Brain, didn't I tell you not to unravel this?"

"I didn't," he said, confused. She looked up at him with dawning clarity in her grey eyes. "Dear gods," he laughed. "You're not going to remember any of this, huh?"

"Any of what?" She padded over to him in bare feet, rubbing her temples.

"Here we go," Percy exclaimed. "Possible side effects… short term memory loss, mood swings, hyperactivity-I can barely read this. I wish they printed Xanathin bottles in Ancient Greek."

"I'm so confused," she mumbled, and went to the fridge for a glass of water. "Xanathin's never given me problems before. I can't remember the last four hours."

"Try forgetting eight or nine months," he put in, still trying to read.

She flinched, then looked at him sharply. "What?" he asked, absently. She shook her head as if to clear it. "Nothing," she mumbled. "You just-hit a bit of a sore spot."

That didn't make much sense to him, given how easily they joked about the amnesia now that it was so far behind them. "It says here that you would only experience side effects if…let's see…" He started to read. "If you took any other meds simultaneously."

"Nope," she said uncertainly, coming to stand across from him. "Not that I remember. Xanathin's the only one around."

"Okay. Well, did you accidentally take more than two?"

"No," she said decisively, tapping her fingers on the countertop absently.

Percy sighed and set down the bottle. "Well, the only other reason for it would be if you were pregnant, so that rules that ou- "He stopped abruptly. She was staring at him with wide eyes, looking like she'd been hit by one of Jason's lightning bolts.

"You're not," he gasped, hoarsely.

She bit her lip, a smile shining in her eyes. "Well, I was going to tell you this week. I found out just a couple of days ago."

Percy stared, dumbfounded.

"Percy?" She asked, uncertainly. "I know it's early, but we're getting married, we're done school, have experience as a couple-I think we're set to have kids, really." Still he said nothing, just stared, stock-still. "Percy?" she asked, nervously. "You all right?"

In answer, he stepped forward and planted a kiss on her lips that would've made even the most experienced girl swoon.
