EDMUND completely froze. He didn't know how to react. He just felt extremely panicked. How could he not when someone suddenly grabbed you and begged you not to kill him and his family? He was not some apathetic being who could stay unaffected after that. Especially since the other was crying so heartbreakingly.
He now suddenly wanted to slap his mouth. If not for his slip of tongue earlier, almost suggesting that the general must have eaten something for him to suddenly fall asleep like that, this teenager would probably not react like this. But he did and now this kid was scared out of his wits.
It was not like it's a huge secret how fierce and scary the general and Fenris squad's reputations were. But he had no idea that it already came to a point where just the possibility of being blamed for something trivial like the sudden sleepiness of their general would lead someone to believe that they – the general and his personal squad – would kill them.
