supernatural robert singer interview as time goes by cw 'Supernatural': Executive producer Bob Singer talks about 'As Time Goes By' and what's coming next

The mythology of “Supernatural” got a sudden growth spurt in “As Time Goes By.” Now that the Winchester boys know that their grandfather was once a member of the Men of Letters, where will the show take us next? Executive producer Bob Singer gave us the scoop.

Warning: There are some big spoilers ahead for both this episode and the following one. Read at your own peril.

We will be seeing the secret location housing the knowledge of the Men of Letters.

Bob Singer: The reveal of that place, which I believe is in the next episode, it’s a really stunning set. It’s full of mysteries. It’ll become kind of a home base for the boys. We’re really excited about it. After 8 years of never having a home base, this’ll be home base for quite some time. And I think you guys will really dig the set.

When they go in there, it’s pristine. Like it’s been hermetically sealed. Everything was just as it was, and it’s perfectly neat. The only sign that somebody had to get out of there in a hurry is a chess game that was incomplete and an ashtray full of cigarettes.

What’s in there?

Bob Singer: If you took Dad’s journal and you multiplied that times 100. It’s got every source of information that would be interesting to the boys.

The Men of Letters represent a big twist in the mythology of “Supernatural.”

Bob Singer: It makes you kind of wonder what Dad would’ve been like, which I think the boys say at the end of the episode… I don’t know if you guys remember the Cupid episode, where he said it was ordained that these two people should get together. And now we know who the grandfather on that side was, and why John became why he was in terms of his relationship with the father. It was supposed to be something different. He was supposed to be a Man of Letters but he became a Hunter out of necessity.

Will we be seeing any more of the Men of Letters?

Bob Singer: They’re all gone. The Men of Letters are all gone. The last surviving one was the old guy in the home, and he’s no more.

The casting of Grandpa Winchester (Gil McKinney)

Bob Singer: He came in and read and we just thought this was the right guy for the part. I thought he did a really nice job.

We were just looking for the best actor and the guy we thought would work well with the boys. And also that there was a contrast. You know, this was a guy who was more elegant and more learned and more educated, and our boys are rough-hewn. So when he says, “Hunter…” He was so appalled at that notion and, you know, came around at the end.

Why was Dean so angry with Henry throughout the episode?

Bob Singer: Dean [Jensen Ackles] had a more complicated relationship than Sam [Jared Padalecki] did with John… Dean, I think, was more conflicted about his dad, and it’s been pretty consistent throughout the show that Dean is always in defense of Dad. And John made the ultimate sacrifice for Dean. So I think he takes this stuff a little more personally than Sam does, and that’s kind of what you see in this last episode, it’s reflected there.

“Supernatural” airs Wednesdays at 9pm on The CW.
