Dem boobs got bigga...
Jk aside, When they made it looks like Wendy is the one that receive the 3rd Origin, my reaction was "Well fuck this losing magic shit" because there is simply no way Wendy, one of the main cast to lost her magic for good, but when its revelaed that Sherrya is the one that actually got the 3rd origin, I'm starting to believe in this losing magic thing and believe she won't be able to use her magic again, at least I still think that Mashima had the balls to discard 1 or 2 side character.
The fight itself is quite underwhelming, I think it would work for the better that Mashima did the 3rd origin transformation at the last panel of the last chapter and dedicated this whole chapter for better prolonged fight with that god so that he can properly showcase the power of 3rd origin and that god.
