Re: Fairy tail 292
After reading the chapter again I think the painting or mural is a picture of what the tournament was in the past and isn't prophesying the future. I think that the dragon is Igneel and that the guy he's fighting is who he got the scarf from that he gave to Natsu(Igneel doesn't seem the scarf knitting type to me). I'd guess that some kind of mutual respect or friendship came out of their battle or maybe Igneel took the scarf as a trophy, since it's clearly magical.
Whatever the case is I think that is Igneel and that is Natsu's scarf, but that it isn't Natsu in the picture.
