As the silence set in, something so strong that it was as if all of the sound had been sucked away, Castiel realized that there was a reason this felt familiar. He let out a breath, remembering that time on the field with Gabriel, and knew that this was the exact same set of sensations. They were being haunted.

The sound of crying hit him then, and immediately he knew it had to be a trap. It was no surprise that Lust asked about it, but Castiel turned toward her sharply, moving so quickly that his stomach seized in pain.

He placed a hand there, but ignored it for the most part, eyeing Lust sharply. "Nothing good. Whatever may be causing this, I've encountered it before. It's a ghost." She would have to believe him -- and how couldn't she, considering she wasn't human herself? The urgency in his body language and tone likely made it clear that this was no joke.
