YMMV / Supernatural S 10 E 23 My Brothers Keeper

• Alternate Character Interpretation: On Tumblr, some have theorized that Dean killed Death by accident when swinging the scythe to kill Sam, hence the brothers's looks of surprise and possibly even guilt when they see Death die. This theory may be Jossed in the next season when Sam and Dean mention killing Death.
• He's Just Hiding: A good number of fans find it hard to believe Death could die, much less in the anticlimatic fashion he did, and have taken to believing that he wasn't actually killed, despite that his scythe was suggested to have the power to kill him all the way back in his first episode and that statements both In-Universe and out have made it clear that he really is dead.
  • Subverted somewhat in Season 13, when it is revealed that while the Character Death is gone, a new Death exists, meaning the title cannot be truly destroyed.
