I liked the chapter but I would rather have Lucy dying in Natsu´s arms to make it more emotional. I really liked Happy in this chapter, his tears always move me. Anyway, the plot "lets go to the past to save the future and lets die to resurrect later" reminds me of SailorMoon. aired at the same time than DBZ, LOL
Anyway it just occurred me that if they dont kill the dragons, humanity ends...but if they kill them, Natsu will be killing his daddy Igneel.
