History YMMV / SupernaturalS05E04TheEnd

* EvilIsSexy: Lucifer with Sam as his vessel is both creepy and a sexy BadassInANiceSuit (white, no less) and evokes a very Zen vibe.

** Given what we find out in "Abandon All Hope", [[spoiler:future Dean's plan wouldn't have worked anyway, as the Colt can't kill Lucifer.]]

** If BadFuture!Dean thought ''his'' 2014 was bad, learning about the ''[[Recap/SupernaturalS09E23DoYouBelieveInMiracles actual]]'' 2014 would've probably broke him...
** [[Recap/SupernaturalS12E23AllAlongTheWatchtower Season 12 reveals]] that the BadFuture shown in this episode is much more preferable to what could actually happen.

** Chuck's advice about hoarding toilet paper is funnier in light of the 2020 Covid-19 pandemic and hoarding that ensued.

** Future!Castiel's "that's how I roll" speech was originally about how his relationship with Dean was the only thing that kept him going, and he was entirely willing to [[TogetherInDeath go on a suicide mission if that’s how Dean wanted to go out]]. Instead Cas is going on about [[HaveIMentionedIAmHeterosexualToday losing himself in women and decadence]].

** Dean/Castiel dialogue from this episode appears in "[[Recap/SupernaturalS10E05FanFiction Fan Fiction]]", in which their HomoeroticSubtext is lampshaded.
* UncannyValley: Lucifer-in-Sam doesn't quite seem to know [[MeatPuppet how to work his face]], which is some pretty good acting on Jared Padalecki's part.

* ActingForTwo[=/=]TalkingToHimself: Jared Padalecki playing as both Lucifer and Sam. Jensen Ackles playing as 2009 Dean and 2014 Dean.

* RiddleForTheAges:
** Is the Endverse an alternate timeline, or was it just an illusion created by Zachariah to manipulate Dean? [[TakeAThirdOption Or both]]?
** Chuck [[spoiler:is later revealed to be God, so why's he still on Earth when even his angels have given up? Does he still have hope that Lucifer can be redeemed, or does he just feel the need to share humanity's fate after having messed everything up?]] However the finale of Season 14 reveals [[spoiler:that GodAndSatanAreBothJerks, and 'Chuck' is just doing all this for his own entertainment.]]

* HilariousInHindsight: Chuck cowering in fear from Dean's angry girlfriend. [[spoiler:Turns out even God fears a WomanScorned!]]

** It's revealed that the reason why BadFuture!Dean is so jaded and broken is because Sam said "yes" to Lucifer. [[spoiler: [[Recap/SupernaturalS13E23LetTheGoodTimesRoll In Season 13's finale, Dean ends up doing the same thing with Michael.]]
