CCS was all about the cards, Lucy's key hunt is more of a side-story. Jellal was a.k.a. Gerard, although I don't see why anyone would care about names as long as you know which character we're talking about.
EDIT: It seems our anonymous "not Jellal" neg-repper is back, just ignore them, everyone.
As for MY crack theory, Kagura wants to kill Jellal because he failed to resurrect Zeref after 10 years and she wanted Zeref all to herself. Discuss
