On A very quiet day at Fairy Tail….
Lucy : Sigh… So boring…
Mira : How about finding a job?
Lucy : Natsu said he wanted to rest for a while
Mira : Lucy, have you considered working with others?
Lucy : Hmmm… But I feel somehow bound to him since we are part of the same team, after all
Mira : You two really get along well… Like a couple!
Lucy : We are not!
Mira : But Natsu might really love you, Lucy
Lucy : *looks at Natsu and Happy having fun with the others* Even if that's the case, I think I'll pass
Mira : You two seem to complement each other, though.
Lucy : *looks at Natsu and the others again* Yeah, I don't think so
Mira : You two complement each other though
*before lucy starts to answer Mira yet again, a loud crack was heard and something fell on top of Natsu*
Lucy : Natsu!
? : Ara, that definitely hurt badly…
Natsu : That hurt… what do you think you're doing crashing on top of me…
? : PAPA! *hugs natsu*
Natsu : Papa?
? : MAMA! *runs towards lucy and hugs her as well*
Lucy : MAMA?!
Guild Members : EEEEEEEEEEEEEEEHHHHHHHHHHHH?!
Mira : Ara, ara!
Lucy : ho-ho-hold on! Who are you and why are you saying that you're parents are me and natsu?
? : Sorry, it seems that my emotions took the better of me, my name is, Nashi Heartfillia Dragneel, I came from the year, X800 , and I'm your daughter! Nice to meet you, papa, mama! :D
Guild Members : FROM THE FUTURE?!
Erza : LU-LU-LU-LUCY AND NATSU'S CHILD?!
Mira : Ara, ara, what a revelation..
Mira : Ara, ara *mira, with her eyes glittering, approaches nashi* ...TELL ME, BEAUTIFUL LOVE-CHILD, HOW MAY I HELP YOU?
Nashi : WAAAAH, it's Auntie Mira!-*cough* excuse me, I came here to ensure that my Papa's future will be secure with my Mama!
Mira : Secured? Why?
Nashi : uhhh, because my Papa is too dense to notice mama?
Mira : True, true -
Lucy : wait a minute Mira-san, do you just accept what she just said?
Mira : well, SHE is a Fairy Tail wizard *points at Nashi's right hand*
Nashi : ne, mama, why don't you believe that I'm from the future and I'm your daughter
Lucy : well, if you could give some evidence..
Nashi : evidence… hmm… AHA!
Lucy : ?
Nashi : Ice Stripper and Water Stalker would end up together and get married
Gray : WHA- WHA- WHA-WHAT DID YOU JUST SA-!
*before gray could finish his words, juvia coiled up on him already*
Juvia : GRAY-SAMA! I ALREADY BELIEVE THAT THIS GIRL IS FROM THE FUTURE!
Gray : NATSU! SHE'S YOUR DAUGHTER RIGHT?! STOP HER
Natsu : don't wanna~
Nashi : and and and, Auntie Erza-SAMA, would get married and become the gui-
Lucy :okay okay, I believe you now, stop spoiling every single thing from the future
Nashi : does that mean that I can stay mama?!
Lucy : err.. getting called mama is a little…. But it's alright for me, how 'bout you Natsu?
Natsu : hmm? That's what she wants right,
Lucy : how about you Mira-san?
Mira :OF COURSE! OF COURSE! SHE CAN STAY! SHE CAN STAY HOWEVER LONG SHE LIKES!
*and thus, a very very strange turn of events started unraveling*
Note : I used some dialog from episode 50 of the anime :D
