"Becca!"

Rebecca shot upright from where she'd been curled up in a large armchair reading. "Caitlin? What is it?"

Caitlin rushed into the common room there at Xavier's school, an excited grin on her face.

"I have the perfect activity for us this weekend!" the brunette stated.

Rebecca sighed. "I thought we were going to take the weekend off from adventuring?"

"Well, yeah, but this is a different sort of adventure! One where we don't need to bust heads!"

"Very well, I am listening."

"This weekend… in New York City… is Comic Con!"

The redhead stared at her sister blankly. "I do not understand."

"It's… okay, so some people write these picture books, alright? And they depict the goings-on of super heroes, real or imagined, and a bunch of other stuff as well… Anyways, so this is a convention where they all get together, the artists and the fans and the merchants, and…"

"It sounds quite convoluted," Rebecca murmured.

"But it's not just comics! They have movies represented too! I mean, yeah some of the movies are based off of comics, but others off of books! Like, you know, Harry Potter and Twilight!"

"I see," her sister commented slowly.

"But I haven't gotten to the best part yet!" Caitlin was bouncing up and down on her toes with glee. "The fans who go? They all dress up as their favorite characters!"

Rebecca blinked her eyes uncertainly. "And how is this fact the best part?"

"Oh, just think of it, seeing some of our friends being portrayed by normal folk? It'd be hilarious!"

"I do not think I would find it as amusing as you seem to."

"Would you seriously pass up on the potential for souvenirs? Like, Hawkeye statues or, I dunno, Captain America tee shirts? We could do all of our Christmas shopping in one weekend!" Caitlin crouched down next to the armchair, her eyes wide and pleading.

"Caitlin…"

"Okay, fine, you force me to bring out the big guns," the brunette stated as she rose to her feet. She stood with her legs splayed apart and her arms crossed over her chest. "We're gonna dress up as well."

"And how exactly does this convince me further?"

"Because... you're gonna be Ginny Weasley and I'm gonna be Hermione Granger."

Rebecca looked at her as an involuntary grin began to creep upon her face. "I am? You are?"

Caitlin nodded firmly. "We are. I found a shop downtown, sells costumes, they got the robes, we can make up wands…"

"Do they have scarves in the color of Gryffindor?" Rebecca asked, letting the grin slip further.

Her sister took hold of her hands and brought her to her feet to stand toe to toe. "They do. You in?"

The redhead gave an uncharacteristic giggle. "Yes, I am in."

A/N: The idea of actual superheroes going incognito to a Con makes me giggle hysterically. I may or may not throw in a second parter for the Con itself.
