Curious that the family name is Winchester. Is that a nod to the famous Winchester Mystery House, or just a coincidence?

(semi) SPOILER WARNING

The ending raises an interesting question as to why two generations of a particular family witnessed the same fate befalling a loved one. Was that family afflicted by some sort of generational curse? And if so, did the same thing happen in previous generations? Perhaps we’ll find out in the fullness of time

END SPOILER WARNING

And I agree that what you don’t see can be (and usually is) more frightening than what you do see. Take _Psycho_ for example. The first murder takes place on camera (though, thanks to careful editing, we never actually see the knife strike the body- we just _think_ we have). With the second murder, when the knife strikes home, the action takes place just off camera. We don’t need to _see_ it to know what’s happening; and Hitchcock left it to our imaginations to fill in any blanks.

I hope _Supernatural_ continues to take pages from that same book.
