Yes. But I don't have the time ( on lunch ) to hunt down the chapter. I believe it's the one where they speak about the part of the thing in the dark being in grey world and about Kate's death following her though

I wonder why Cassie so quickly concluded that creature was what “got her” … referring to previous roommate?

Is this creature attached to that particular room; has Cassie encountered it before? She seemed unsurprised, almost resigned.

With all of the inhuman entities on campus, why the immediate conclusion that this particular monster got her old roommate?

Hopefully she opens up to Ashley; clearly she has some reason for what she said.
