considering how their development is rather similar to Rave Master's main characters...And we know how Rave Master's main characters ended...
Finaly someone with a theoretical idea :P. Well maybe you could explain why they would end up together?
The things i can think off
-Lucy fills in the place Lisanna left open.
-Natsu came to her rescue
-Nastu always in her room
-In the last Omake it was all NatsuxLucy centered.
As anti elements
-Natsu might still feel for Lisanna
-Natsu might see her as a comrad
-Natsu also rescued Erza in a similar matter
I must say most interactions in general are Natsu centered. Well thats about it from me ^^
Well, there's 4 factors that you stated was Pro-NatsuxLucy compared to the anti-elements that only have 3. So I'd say chances are pretty big for them to end up together.
I think I've said enough when I said that they are best friend don't cha think? Beside I didn't say that they are just best friend but they are the best of friends. How many best friends have we all know that have ended up together or even married? There you go...it all started with being as simple as bf.
I love Lucy and Loki more
Lucy and Natsu probably just good friends
but in the end of the FT, I don't think sensei will say anything about love!
Well it's not like Natsu is completely clueless when it comes to women.I mean hear in this page he and Gray are blushing when they checked the bathroom to see where Lucy is.
Seeing that the meeting of Natsu and Lucy is like the meeting of Haru and Ellie,I tend to think that Mashima is going to build their relationship slowly like in Rave.
maybe we know he was interested in a woman before in Lisanna so maybe he will like Lucy eventually.
Was natsu ever interested in lisana that way? Surely lisana liked natsu but you have to remember we are indeed talking about natsu. somehow he does not strike me as of being in love with lisana and do "in love" stuff with her.
Lucy isn't interest in natsu. Her feeling to him ale same as 1 chapter. She see him more like comrad powerfull one and dummy one.
Natsu don't really look for Girl, and i don;t think he look for one. Now he want to be strong and find dragon. Lisarna was actually one who made first step.
Well this is cliche, we are talking about Mashima... here... In Rave Master, the three main characters are all have bf/gf at the end lol. One is obvious, another one kind of tragic, and one is actually comrade untill 'you know who' try to claim the girl as his wife, i think thats when he realizes he doesn't like other guys too close to the girl. Well Mashima give so many hints before that, i really like to discover every hints he threw.
But you must now Haru and Natsu are different, in term of characters and personality and so does Elie and Lucy. But it is not impossible... because we are talking about Mashima. Another couple that i know in the making is Erza (that is freaking obvious) but save that for another thread.
And i think Omake considered canon. It will be a long slow painful process untill we got to see Mashima pairs them up. I got a feeling there will be an arc about Lisanna story, and maybe from there we got to see some answer if Natsu actually ever interested in her, and how will Lucy's response.
Meanwhile enjoy the current Edora's arc.
I want natsuxlisanna:P
I don`t like lucy too much,Erza is better than her:P
So maybe natsuxerza?:PP
I need the next chapter,maybe everything will be revealed:P
I don't think natsu was "in love" with lisana nor was in love with lucy. I mean, look at the guy. I don't think he quite gets it. He does seem to have a special friendship with them though.
Well just before this arc Gildarts said he expected Natsu and Lisanna together (he didnt know she was dead). Natsu does have feelings for Lisanna but its not easy to tell if its just special friendship or still somewhat more.
