Oh shit that's a knife against her throat and while Gideon likes how tough Darcy is, she really wasn't looking for a do-over of Harrowhawk. She has had enough of threats to kill her.

Especially confusing threats when Gideon turns her eyes (and absolutely not her neck) to look at Darcy. "I... broke into my room."

And she vaguely gestures to Gideon's scant belongings on her side of the room. Weakly joking, she adds, "Behold, my vast pornography collection that I'd rather you didn't kill me over because it's irreplaceable."

Gideon still has her hands on Darcy's legs and if that knife moves at all, she's going to take the world's stupidest chance and powerslam this girl into the nearest wall, and hope she can do that faster than the knife can cut. Is that possible? Probably not. But she'll do it anyway.
