That’s a great point. When Myne was attacked by the trombe as a blue shrine maiden, Damuel was almost executed simply because he didn’t signal for help when a higher ranked noble attacked Myne. So Damuel’s inaction due to his incompetence just with regard to following Ferdinand’s order was enough to be executed. Of course, he was a laynoble, so far less important.

I expect that even though Wilfried’s attendants are archnobles, this is a far more serious crime. But maybe on the balance, because they’re archnobles, they think they might not be executed because their mana is needed?

This next paragraph may have spoilers. It’s all stuff that’s already happened in the anime, but maybe wasn’t explained fully in the anime, I can’t remember, so I’ll mark it as spoilers. For example, did Florencia specifically say in this episode who was raising Wilfried before? I can’t remember. I do think most of it is stuff that you could assume from the anime, even if it wasn’t explained.

Some things already shown in the anime, but with maybe extra info from the LNs

Previous to this arc, Wilfried’s upbringing was left to Veronica, and that was only about half a year before this episode. I don’t know that Wilfried’s attendants could go against Veronica. It may be that they simply believed Wilfried was doomed to fail his winter debut, but since Veronica seemed to think it was okay, it was going to be okay even without her. And they may have thought 9 months wasn’t enough to fix what Veronica had broken, so maybe they’d get out of the situation by blaming her.
