[a little more seriously] They're not a threat because there is no fight here. There's no Area 11, there's no Britannia, there's no war. They have no need to do anything to anyone, and I've been watching them, and they've taken no overtly hostile actions.
The warden has a small security team but isn't especially interested in saving lives. I founded the defense force here, and I will protect everyone I can until I have evidence that they're doing something to betray my faith.
Britannians, Japanese, even Zero himself.
[his tone is serious, and firm. he's not criticizing Guilford, who has just arrived and probably finds this all very difficult to understand. he's just sharing these facts, for the knight to make of them what he will]
