Well the answer to that is with the spirits I guess. Both Caprico and Leo seem to know more than what they're letting out regarding Lucy and Layla.
I get it! Natsu and Zeref must be Twins! lol
No, that can't be because they don't look alike. I guess that these two must've met each other in previous life or something like this:
Zeref: I am you, from another dimension.
Natsu: I've already met my 'other' self in another dimension. You're not me. Liar!
Zeref: But I am from another dimension than that. In that dimension, I was (you are) married to Lucy.
Natsu: What!? Get the hell outta...
Zeref: By the way, we had five children.
And Happy is our pet cat.
Hiro Mashima has already stated that Natsu is not over 80 years old, so what he says goes. The only plausible theory for not being able to pass the runes is his Dragon Slayer magic which is a Lost Magic. The same goes for Gajeel. That and it's been shown that Natsu ages normally like any other human. So I highly doubt he, Gajeel, Wendy or any other Dragon Slayer is over 400 years old.
There is no doubt there's some kind of connection between the two however, since Zeref knew who Natsu was instantly and Natsu having no idea who Zeref was at the time.
could it be possible that natsu is the reincarnation of someone ? someone legendary like zeref only on the good side?
Could it, should it, can it? and.....anything is possible..
i do have a feeling zeref is going to have something to do with why natsu was an orpha. being raised by igneel
and perhaps something to do with why the dragons RUNNOFT
I think Mashima will go with the Father and Son relationship ....
This is why Natsu can't remember anything about Zeref.
Also I think that Igneel is fully aware about the fact that Natsu is Zeref son, and he recognize Natsus power, and that he's the only one that can defeat Zeref, because they both have same blood running in their veins.
one thing that kind of dissapoints me about fairy tail is that natsu doesnt appear to be actually increasing his power level or strength
like when he fought jellal he ate the lacrima
when he fought the "god slayer" guy on the island he ate up those weird flames, when he fought hades he ate some of laxus's lighting
i mean when is natsu going to step up and beat a boss type character, of fight one based on the strength he has built or some new badass ability
i mean he did beat laxus somewhat on the roof in that arc, but he hasnt really gotten progressively stronger as fairytail has gone along, perhaps this latest thing that ultear did when they were training may make him a good bit stronger
but back on topic
i agree with ifirit that it seems they could be related in some way if not father son maybe a distant relative as zeref either appears to have been ancient or reincarnated
the fact that he was found on fairy tails sacred island also leads one to wonder about their relation
i assume mavis knows a GOOD BIT about zeref
Also, expanding on that theory, maybe Zeref is the same, but he forced himself into a younger body when his current one wore out, and the new body's soul is (was) fighting Zeref's malice, thus creating the emo Zeref we know and love. Soon enough, however, Zeref will be back to normal (evil) again.

i agree with the black dragon slayer part but not the father and son relationship
Zeref is a DS who was raised and teached by Acnologia
Natsu lineage is very special comparing to others. That's why Zeref is sure than Natsu is only one to be able to stop him. Possibly Natsu and Zeref are like Ying and Yang. Darkness and Light itself. Possibly Natsu is the artificial human created by dragons for only one purpose - to stop Zeref.
i disagree that natsu is an artificial human... for the main character to be found as "artificial" so late in the series in kind of sad. there hasnt been any hint at all of any artificial humans in the series so far.
i also disagree that zeref is a DS. then why doesn't anyone summon dragons. why doesn't he use dragon slayer magic. i'm sure he can summon other stuff from his "dark book of spells" (?) like those rock golems or whatever, does that mean he's a golem slayer? although he said the dragon was summoned by the malice present at the time, it is unclear to me whether the dragon came because of zeref or not.
i do agree with natsu being the descendant of some one or relative to zeref. just a gut feeling. though i have no evidence.
I don't think Natsu's a descendant of Zeref. I'd say its the relationship they had in the past. Maybe Natsu was a dragon back then or dragon slayer. Whatever took place years ago, I get the impression that Zeref might be different from what he was shown to be in Tenroujima arc. 400 years ago, I get the impression that Zeref might have no value for life. You could say he's a down right badass villain who may think of humans the same as Acknologia did. There is the high probablility that it's Natsu that made him realize the importance of life. The two must've been in equal strength. The only thing clear is that it didn't end with a solution. Zeref went where there's no person there. He basically hid himself.
Natsu and the other dragon slayers were probably reborn as humans. Maybe 400 years ago, the dragon slayers themselves don't have good relationships as stated by the conversation between Grandeen and Igneel. Every Dragon slayer must have their own beliefs. Maybe Natsu's was completely different from the others.
