You know what is really sad...

Every other dragon slayer's dragon parent is alive, and they will be all glad to see them again, while Natsu is now there all by himself with no parent. If Gajeel ends up being ungrateful and gets mad at Metallicana for leaving, and does it right in front of Natsu, he may end up really pissed. I really doubt that Mashima will go that in depth though, and all the dragons are probably going to leave.
