1x16 The Haunting of Nancy Drew

Right after Nancy found the box with her mother's silver steak knives in it and one was missing, I happened to think that the murder weapon wasn't "a" murder weapon at all but that it was probably used to cut Lucy's umbilical cord. Or would it be the baby's umbilical cord? I have no idea which one an umbilical cord belongs to. Point is, I thought the knife was probably used to cut "a" umbilical cord. I wasn't expecting that to be the case, let alone revealed to be exactly that, in the same episode. Of course, the more specific details behind that thought was far from correct, like Lucy was waiting for Ryan at Dead Man's Bluff to tell him that she's pregnant, a long time passed and he didn't show up, so she called Katherine or contacted her somehow out of desperation, only she specifically mentioned to her that she was pregnant, which is why Katherine grabbed one of her knives before going there, and that was pretty much where the thought ended. But "the" thought itself, if that makes sense, was, actually, correct. Wow. This was easily the best episode of the season. It was nowhere near as mentally straining for me as previous episodes have been. It was easy to follow. And it was just an all-around good episode.
