Lol I remember as a kid my friend asked me where I was in Fairy Tail and told him "Wendy just joined" He told me get ready for the biggest WTF moment of my life
I just realize in this ep.. I think the quest wa sthe 100 yr quest? Looking back now I just realised since in the ep 1 of 100 yr quest he mentioned the same words too I think nearly
So... Gildarts wasn't able to finish the quest because he encounters Acnologia and nearly killed him, but I'm pretty sure he could at least have taken the water god from what we have seen in the 100-year quest arc
since when does Shanks from one piece has Zorro's sense of direction and end up in fairy tail.....the animation indicates that it was around the time before blackbeard....he has no scar yet...
