Laven!! Awesome, I'm glad somebody was thinking the same thing as me, though I think many people think there is some form of connection between Zeref and Mavis...

And yeah, I considered Natsu being related to the two because he is obviously popular with Zeref (why just look for Natsu on Tenrou when Gajeel and Wendy were there too) however then I remembered that people in the guild have memories of Natsu as a child... and the age would be an issue. However, maybe Zeref has some really close connection to Igneel and wants Natsu as Ingeel's son?? Hmmm.... lol idk XD
