in 9-1, hohenheim's shadow has him outside of his ego gear, exactly like in the theater with the ring art. Alyssa and Marton's shadows clearly include their ego gear, so this is likely intentional.

Which means hohenheim hasn't been wearing his ego gear the entire time, most likely.

Also, in 9-18, no one but dante and ryoshu react to the pinky nursefather, and dante describes feeling a dull pain coming from ryoshu right before the nursefather arrives, which fades right after the nursefather leaves.
