Sarcasm is an adjusted stress reaction.

I don't think I fit into any of those categories. I felt that the end scene felt like it came out of nowhere, had little to do with what had gone before and just didn't fit. But I felt the whole episode felt weak. The first part was creepy, the second not so much even though the angels were moving and looked like angels and there was the whole "don't walk into the light!" section. It was a bit boring really.
