Mariya, the sniper for the Grendels, is coming up with an escape plan from the facility that they'll be placed at soon the moment Signum leaves. She then she learns that the place is going to be secured by Hayate, Nanoha, and Vita among others. The Grendels' response is appropriate.
Mariya: "We've got no luck... No luck at all."
Then it's even funnier when it turns out that Thoma is unaware of why they were shitting themselves because he is oblivious to Hayate's reputation as the "Living Lost Logia".
Later on in that chapter, we have one of the Grendels essentially going "This whole place is crazy." Once again, Hayate was assumed to be an intimidating and scary figure, but her adorable smile unnerves Kurt.
Or when Kurt uses his ability to teleport his teammates to them, all of them falling naked on his arms.
