Prompt from Axel Treehorn: "You know, when Percy grows up, won't it be confusing to tell who the real Poseidon is?"

Some muffled, belligerent conversation: "No, I don't see the point… It's like any other time we've gone shopping– Mom please…"

"This is such a momentous occasion! This happens once in a lifetime–"

The audio clears, and a groan is heard. "Grover, why are you filming this?"

"Like Sally said, it's a momentous occasion."

"Mmhm," agrees Thalia, off to the side. "It's not every day that someone buys their first suit."

"Well, obviously not ."

"Come on, Percy. Everyone agrees that this should be documented– right, Annabeth, Nico?"

"No arguments here."

"I think it's a very big experience."

"You planned this, didn't you? That's why half of Camp came shopping with me today. Bringing me into Men's Wearhouse wasn't coincidence at all!"

"Regardless–"

"Mom!"

"You needed a suit for your Olympus meeting, and you know it. I just thought your friends should be along for the ride."

"This is payback for going to Greece last week without telling you first, isn't it? I told you, it was very important business! It couldn't wait!"

A tsk. "I don't know where you get these ideas. Why don't you try on this blue suit next…?"

There's grumbling, then the shh-cht of curtains closing.

There's a comfortable silence for the moments until the curtains opened, and Thalia's poorly disguised snort of laughter.

"I don't think teal is my color."

"Nonsense. It's just not right for the suit."

"Y'know… Won't it be hard to tell who the real Poseidon is when Percy's older?"

"Uh," said Annabeth, "What do you mean?"

"You know… Since Percy looks sorta like Poseidon, with the black hair and tan skin and… fantastic… facial hair, won't it be hard to tell them apart, once Percy's like mid-thirties?"

"Grover, I told you, I'm working on the goatee –"

"I would agree... Except Poseidon can change how he looks at will, right?"

"What do you mean?"

"Well," Nico continued, "Poseidon can look like he's human, with black hair and likeness to Percy, but he can also change how he looks… Like he can turn into a horse or a fish… It gave him ten extra points in Mythomagic… Is that not real?"

Silence met his words, until Annabeth said: "No, you're correct."

Shocked silence met that, and she continued, defensively and hurried: "Not the Mythomagic part, I have no idea about that, obviously, but the metamorphosis– that's true."

"Hmm…"

"I think the gray suit looked a lot better." Sally, trying to repair the awkward atmosphere. "Teal is not a good suit color. But ties, on the other hand.."

A groan. "There's more to this suit stuff?"

"Loads more." Thalia sounded like she was smirking. "Ties, pocket squares…"

"Patterned or un-patterned for each…"

"Shoes…"

"Ugh."
