This was deliberate yes? An in joke? That's how I read it. I kinda laughed out loud when Tuesday was mentioned. (As in Mystery Spot Tuesday). Surely
they couldn't have that big of a mistake... It's just far to damn obvious. I took Crowley's "Tuesdays, what could go wrong" as a bit of a wink. And Jensen's "nope". Also Jared's emphasis on "ever". Maybe I'm making the wrong assumption?
