Hildibrand suffers the same fate (incredibly lame pun), you need to do Fates in order to complete his quest line as well.

Really? I don't know who at Square Enix thought that more FATEs should be added, but I would very much like to find out who. The entire system is still a mess. We had to deal with this same crap with the Lightning event, so if this is how future content is going to be implemented, I don't feel very positive about the future of this game.
