Indeed it was a chapter full of win. Gray being worried about Juvia, Laxus's old team happy to see him, Gildartz being... Gildartz. It's still hard to say what Zeref is all about, but I hope it's complicated and Jellal will come back in that arc at the very latest (assuming it's not already the next arc). Preferably sooner, because he's one of the very few characters who really faze Erza.
