Fullmetal Alchemist, Vol. 03 - Hiromu Arakawa More creepy characters started to showing up: the 2 transmuted robots? who were really 3 brothers -assassins- when they were alive.

The only light moment may be when Ed and Al were at Granny's home, getting fixed. Oh, and when this bookworm Seska helped them with a book. (OMG to burn a library with thousands and thousands of books! Sacrilege!)
