Lex opens her eyes and sits up. She isn't sure why, but she is FREEZING!
"It's so cold in here! What the heck, guys?!"
Everyone gathers around Lex, who has been haphazardly slumped onto a bench. She's a bit miffed they just tossed her into a seat. Natsu is laughing at her.
"Idiot! How can you be cold? You really are stupid!"
"Because it's cold in here, alright? Why are you being such a jerk?"
"Whatever, squinty eyed freak."
She stands up quickly, hands on her hips.
"What did you call me?! Lucy, can you believe this-"
She turns and looks at her friend, who is currently looking over someone lying on a table.
Someone with long, wavy black hair like hers.
Wearing her clothes.
Who has her exact body type and face.
Lex breaks into an ear shattering scream, stumbling backwards. She finally realizes just how much deeper her voice is.
"OH MY GOD! OH MY GOD! WHAT DID THAT BOY DO TO US?!"
All eyes are on her now, except she isn't herself. She reaches up and her hands touch bare, toned pectoral muscles. She feels weird, all masculine and crap. Not to mention the other oddities of suddenly becoming a man.
She runs her…his? She runs her hands through Gray's hair, her eyes wide with shock. She can even feel the scar on his forehead with her fingers. Natsu pokes her a little.
"You sure are acting weird…What's up with you, Gray?"
"I'M NOT GRAY! I'M LEX!"
"Haha, very funny."
"I'M SERIOUS!"
She looks around frantically before running up to Lucy.
"Lucy! You know it's me, right?"
"Um…"
She leans forward and whispers something in Lucy's ear. Whatever it is, it's something only Lex should know.
"You ARE Lex!"
"Ugh, why does my back hurt so much?"
They all turn slowly and look at Gray, who in true Gray fashion is in his underwear.
Except its Lex's body that's in her underwear.
She rushes over, frantically trying to cover her body. Gray takes one look at her and screams.
"That's my body!"
"AND THAT'S MINE! GET DRESSED!"
Gray looks down at himself and his face turns so red it's almost glowing like a stoplight. Erza is stalking over threateningly.
"GRAY! QUIT BESMERCHING LEX'S VIRTUE!"
"I DON'T EVEN KNOW WHAT'S GOING ON!"
Lex finally manages to get Gray redressed, much to every other male guild members disappointment. She sits down, her head in her hands as she laments.
"I'll never be able to look them in the eye again…"
"Um…Lex…"
She opens her eyes again and realizes there's ice in her lap. Only then she notices she's drooling ice.
"Oh…Oh crap…I don't know how to control Gray's magic!"
Gray takes a step forward and suddenly starts sinking into the ground. Lex pulls him out quickly and drags him over.
"You think that's a problem?! I can't walk without falling into a shadow!"
"Where is that boy?!"
Bisca holds something out to her.
"He ran off, but he left this behind."
Lex opens the book and lets out an irate groan.
"Changeling magic? Really? That's illegal in Fiore!"
Lucy looks over her shoulder at the book. Most of the words are complete gibberish.
"Um…maybe there's a reversal spell?"
"I guess, but I can't read any of this…"
Natsu grabs the book, looking at it.
"I can read it."
He says something and Lex's vision blurs. When she opens them again she can feel that familiar top heavy weight and grins.
That is, until she sees strands of blonde hair fall in her face.
"Oh no…"
Natsu and Loke look at each other and scream, as does Erza and Happy. Lucy is in Lex's body and poor Gray has switched places with Macao. Everyone else in the guild seems to be themselves.
The next few minutes are a horrifying mix of Happy trying to reequip, Erza falling into depression, and Loke drooling fire everywhere. Everything has officially fallen into chaos when the master returns.
"What's going on here?"
They all turn around and cry in unison.
"MASTER HELP US!"
Lex hurries over to him, pleading.
"We've switched bodies! Help us!"
"How did that happen?"
"Some weird book! A boy had it and it ended up here and Natsu read it and-"
"Okay, okay, I get it. I was looking forward to punishing you guys when I got back but I guess it can wait."
He looks them all over, thinking deeply. Then he grabs the book and thumbs through it. Little fuzzy Erza approaches him.
"Do you have a solution, Master?"
"Nope. I don't know."
Lex is about to burst into tears. She can't stay as Lucy! She doesn't even know how celestial magic works!
"We're back!"
They look towards the door and see Levy enter with her friends, Jet and Droy. Well, friends isn't really good term…they're more like Levy's personal cheerleaders than anything else.
Lucy rushes over to her.
"Levy! Can you help us?!"
She explains the situation and Levy nods before running around gathering books and sitting down to decipher the spell.
Nearly an hour passes before she jumps up.
"I got it! Just let me cast it!"
And that was how every single person in the Fairy Tail guild hall had their bodies swapped around. It took forever to find someone with the proper knowledge to break the spell.
Lex will forever be scared for life after having to dwell in Natsu's body for so long. Needless to say, they burned the stupid book.
Chester wasn't too happy when they came around looking for his grandson either.
Especially since it was an angry mob of Fairies.
