Eric Kripke’s hugely popularSupernaturalhas many highlights, and Misha Collins' favorite episode features a particularly wild storyline. Since its inception in 2005,Supernaturalaccomplished many impressive feats. The first was bringing exorcism horror to an Americana road story, while another was constantly reinventing itself to stay relevant over the years. Fans need look no further thanthe many versions of Sam Winchesterto see this strength.Supernaturalhaving multiple versions of a main character demonstrates exactly the kind of meta storytelling that Collins appreciates in his favorite episode.
Playing one ofSupernatural’s best supporting characters, Castiel, Collins has an opinion worth considering when it comes to the show’s best episodes. Castiel joined the show in season 4’s “Lazarus Rising,” which in itself could be on any self-respecting list ofSupernatural’sfinest moments. This installment introduced a character that would grow far beyond his original supporting role, making it a key milestone in the show. ButCollins' favorite episode comes from halfway through season 6, and it is rightly recognized as one of the outing’s best.

Misha Collins' Favorite Supernatural Episode Is “The French Mistake”
Misha Collins Appreciates The Show’s Most Meta Episode
Collins spoke toE! Newsand confirmed that his favorite episode is “The French Mistake,” which findsSam and Dean Winchestertransported to another reality. In this episode, the angel Balthazar slams the Winchesters into this version of existence to temporarily keep them safe while Raphael is hunting down Castiel’s allies. What makes the episode so meta is that,in this alternate reality, they are not actually Sam and Dean Winchester. Instead, they’re Jared Padalecki and Jensen Ackles, two actors playing Sam and Dean Winchester in a TV show.
In this episode, Padalecki and Ackles play Sam and Dean becoming Padalecki and Ackles playing Sam and Dean. As you might imagine, it’s completely absurd. Despite the tentative pioneering ofBuffy the Vampire Slayerin making humor meta for fantasy TV,television had never quite seen the likes of “The French Mistake.“As Collins stated, “It was brilliant and daring and ridiculous.” And that made it completely hilarious. Thankfully, Eric Kripke was able to build on this strand of satirical humor, resulting in an even bigger TV series:The Boys.

“The French Mistake” is one of thebestSupernaturalepisodes that break the formula, sacrificing the series' usual style for a radical new concept. Kripke agreed, confirming toEWthat it “can break format.” Debuting on August 01, 2025,“The French Mistake” proved thatSupernaturalstill had new ideasand could still challenge boundaries and norms in television. It is episodes like this that raiseSupernaturalabove standard fantasy or horror television, exploiting both serialized and episodic storytelling to provide both brilliant standalone episodes and longer arcs with deeper meaning.
“The French Mistake” was written by Ben Edlund and directed by Charles Beeson.

The deep relationships inSupernaturalblossomed over multi-episode narratives, allowing the space for excellent standalone episodes like “The French Mistake.” It was probably the funniest hour of television that year, and it inspired future brilliant episodes like “Fan Fiction” in season 10. Ackles' “I’m a painted whore” line will be completely immortal, especially given the cutting social commentary that came before it. (Ackles was minorly accosted by a crew member, calling back all too many real-life incidents.) “The French Mistake” really wasSupernaturalat its finest.
