"Nothing you can say would sway me," Caitlin declared from her seat on the couch.

"I get that, but you're still wrong," Bobby replied cheekily, sitting on the floor in between Rogue's legs. The teenagers were gathered in the common area of Xavier's mansion after dinner, and somehow the conversation had taken a rather dramatic turn.

"Wrong?" she replied, her voice raising. "Wrong? How can I be wrong? You're talking about a thing that has become so diluted, so… so… old. Outdated."

"But wasn't Firefly aired, like fifteen years ago?" Kitty murmured to Blink.

"That doesn't matter!" Caitlin whirled to face her other friends. "It's still relevant! Still the greatest television show ever to air! And then Serenity? Wouldn't have happened without the fans who rallied and gave the mighty Joss Whedon their support!"

"'Mighty'?" Rogue snickered softly.

"Hush, she's on a roll," Blink grinned.

"And the cast on the show!" Caitlin exclaimed excitedly. "They meshed so well! Created a sense of.. of… of family! Yeah, a broken and dysfunctional one, but still, a family! They were so good, especially Summer Glau!"

"Yes, we are aware of your infatuation with Summer Glau," Rebecca murmured from next to her sister on the couch. She had a book open, quietly reading while still following the conversation.

"Yeah, that's cool and all," Bobby interjected. "But Star Trek? Way better. Fifty years of TV shows, which there were six of by the way, twelve movies with another about to come out…"

"Exactly!" Caitlin proclaimed. "It's way more diluted! Firefly had more story and character crammed into a single season that all of that!"

"Seriously?" Bobby scoffed. "Do you even hear yourself, fangirl?"

"Becca, back me up here," Caitlin pleaded. "You watched the series with me, you liked it, right? And the movie, you said it was awesome and all?"

Rebecca nodded slowly, her nose still buried in her book. "Yes, they were quite good."

"Thank you!" her sister proclaimed triumphantly.

"However, I believe the Harry Potter movies to be superior," Rebecca amended.

Caitlin leapt to her feet, levelling a trembling finger at the small redheaded girl sitting at the end of the couch. "Traitorous harlot!" she declared dramatically.

With slow, careful motions, Rebecca placed a worn Air Force bookmark to mark her place and closed the book, gently placing it to the side as she brought her impassive gaze up to the petite brunette.

"Now… Now, Becca, I didn't mean it like… Okay, yeah I can see the qualities of Harry Potter and all… Becca, don't… No, no, Beccaaaa!"

With a wail of terror the brunette sprinted out of the room, her sister on her heels in a flash.

The other teenagers erupted in laughter, which only increased as the shrieks sounded from elsewhere in the mansion.

"I don't get why Cat is so scared of Becca, though," Peter chuckled.

"Well, the way I understand it," Kitty replied merrily, "Becca discovered a very important difference between the two of them, something Cat has that she doesn't."

"What's that?"

"A ticklish spot."
