The interactions between Natsu and Lucy when they got up on the mountain was just hilarious. The clock is brilliant, and the fact that it talks for Lucy, in the third person as if written in a book or something is just so damn funny. I'm still laughing just thinking about it.
The guild master is certainly an interesting one, seems he doesn't care so much about authority, just the paperwork. Lucy is also now a member of the Fairy Tail guild.
Pretty eventful chapter there, and very enjoyable too.
