I would have spit on Wendy if I were Natsu and Lucy and ditched her ass and that annoying cat. How dare you deny coming back to Fairy Tail, the guild that gave you a home when you had no where to go just because you want to sing with Chelia. Trash.
Anyway, I love Lucy's powerup! Finally much needed progression in powers and abilities. Just looking back at episode 1 where should could barely handle one spirit and now she can do so much crazy shit! She has the most improvement by far of any character [because she had the most room for it].
Has Happy really done nothing though? Is he just for comedy? The two cats can now both fight while he's just there to help Natsu fly.
