Graf: "Somehow I suddenly got this urge to kills someone...."

Graf: Pulling out her phone "Iowa? This is Graf, I want to ask you for a favor."

When you suddenly feel Graf Zeppelin arming the Me 155A's, Ju 87's and Ta-152C/R14's within the base

You heard the man. Keep your glasses on, Miss. It's hotter that way.

Who suggested they were Abyssal spies, because I think you might have called it.

Knowing Ido-sensei, Nagato's line could be a red herring. I doubt he'd make it that obvious if Kashima and Katori were Abyssals themselves.

Maybe Katori is being genuine in her plea for help and the Abyssals are involved indirectly (coercion, black mail, brainwashing etc). Though her stripping would be puzzling in that scenario...

My favorite part about Ido's stories is that I can't predict anything.

The Kashima has shark teeth. Given how many times abyssals have infiltrated in this work by now, it would be more surprising if they weren't spies.
