I'm currently watching Supernatural for the first time on Neflix. In Season 4, there are several extremely self-referential episodes in a row. They are:
- 4.17 "It's a Terrible Life"
- 4.18 "The Monster at the End of This Book"
- 4.19 "Jump the Shark" (I haven't watched 4.19 yet, but I'm assuming it is because of the name and description.)
I'm wondering if there's a reason that these episodes were grouped together. Usually, the more 'light-hearted' episodes are scattered through-out a season, rather than put in one large block. The timing seemed really jarring, especially after the extremely epic 4.16 "On the Head of a Pin".
Is there any explanation from the show's creators as to why they choose to do this? Was this at a mid-season break?
(Please avoid spoilers if possible. 4.18 is the furthest that I've watched. I'd be fine with answers like "There's something bigger or darker than every before on the way" as long as there aren't specifics.)
