It's following the manga pretty closely. Everything that we saw in this latest episode was in Chapter 5 of the manga of course with minor differences (Nina actually called Ed "Mis-ter" in the manga when she was changed into a Chimera and it was what triggered Ed to realize it was her) Things are going to start moving pretty quickly here with the Ed vs Scar, Dr. Marcoh, lab 5, and Hueghs.
Also that french guy (Yoki) shows up a lot more later on in the series
Well technically they don't.
Spoiler: show
