So... Am I the only one who figured out what Kagura's kiss meant? She knows that Erza loves Jellal, and since she "kissed" him to save him, which was actually CPR, she kissed Erza as a means to "transfer" the kiss or something like that. Either way, it had to do with the CPR "kiss" and Kagura's still a bit clueless about love.
