They pass another cottage at one point, but this time Dean gives it only a passing glance before striding on, muttering under his breath about creepy-ass taxidermists.
This time, it's Castiel who stops.
He hears a clicking, a whining from the shadowy archway. He turns.
Dean has a small moment of panic when he realizes that Cas isn't besides him anymore. He isn't much calmed when he whirls around and sees his friend standing as if frozen in front of the yellowed cottage.
"Cas?" he calls out.
Castiel doesn't answer, just tilts his head and narrows his eyes at the doorway. Dean jogs over to him.
"Cas, wha-" His eyes pass over the entrance to the cottage, and he does a double-take. A pale, mask-like face is suspended there, with wide, empty eyes.
Castiel's voice is unnervingly calm when he says, "It's trying to tell us something."
