"How horrifying!" But a frown is crossing Laertes's brow as he tries to envision it. He's been reading a fair bit about physics lately, and his reading has touched on acceleration due to gravity and the force equation.

He understands now why Lan Wangji and Alex believe there was an unseen hand wielding the blade.
