'''Dean:''' HeyaHey, Sammy.<br>

When Sam answers one of Dean's many cell phones, the man on the other end asks for an "Agent Bon Jovi."It's also [[Dean's Cell Phone | Dean's Other Other Cell Phone]] which is often heard in the show on voicemail whenever someone calls him.}}{{TriviaQuote |Text='''Bobby:''' Rufus lives about five miles that way -- with Aretha. Thought she'd have better taste.:''"Aretha" is possibly a reference to R&B and soul singer [https://en.wikipedia.org/wiki/Aretha_Franklin Aretha Franklin.]''

In a [https://variety.com/2020/tv/news/how-supernatural-filmed-during-covid-19-1234772638 ''Variety'' article], director [[Robert Singer]] talks about COVID-19 restrictions, quarantine, and which cast members were on set for the series finale. Some fans were upset by the news that [https://twitter.com/mishasnovak/status/1306853261408980995 Misha wasn't included.] Jensen also [https://screenrant.com/supernatural-final-season-15-script-changes-pandemic/ confirmed] that there had been changes to the script due to COVID. Both [https://www.youtube.com/watch?v=L3LRydtQZVY Misha] and Jared [https://www.youtube.com/watch?v=csmqSQAQHHg later went into detail] about these changes to the ending, specifically saying that there was supposed to be a large scene in Heaven of all of Dean's friends, family and loved ones from earlier episodes, but that it wasn't possible because the 14-day quarantine would've been inconvenient to cast members. However, [https://twitter.com/katramdeen/status/1330629428448096256 Kat Ramdeen said on twitter] that she was already available in Vancouver and was not contacted, and [[Samantha Ferris]] [https://twitter.com/samanthajferris/status/1330683416417771523 said on twitter] that she and [https://twitter.com/ChadLindberg/status/1330658189335957505 Chad Lindberg] weren't approached about being in [[Season 15]] at all (despite many other [[Season 15 Callbacks]] prior to COVID restrictions being enacted), and were surprised to see [[Harvelle's Roadhouse]] in this episode.

When Sam shoves the pie in Dean's face, the extra in the background who appears shocked is director/producer [[Robert Singer]]. [https://www.youtube.com/watch?v=2oVQe8h0-H4 Jared revealed at Creations StageIt event] that this scene was scripted, and that he got to enjoy hitting Jensen with the pie multiple times as needed for filming.

:''Sam and Dean's exchange as Dean is dying is verbatim from [[1.01 Pilot]], when Dean asked for Sam's help in finding their father. When asked at a StageIt Creation event the weekend after this episode aired, [https://www.youtube.com/watch?v=2oVQe8h0-H4 Jared said], '':''"It was written that Sam says, "I can't do this without you." I thought it was neat to throw back to the pilot and say, "I can't do this alone," instead, like to reverse roles." ''He also said he and Jensen were given license by writer Andrew Dabb and director Robert Singer to "just go with the flow" during Dean's death scene.''

After Dean's death, Sam starts wearing [[Dean's Watch]] and is seen wearing it up until his death. Jared revealed at a [https://www.youtube.com/watch?v=2oVQe8h0-H4 Creation StageIt Creation event ] the weekend after this episode aired that this was an idea of his and Jensen's , that Sam would keep Dean's watchafter Dean's death, and he was surprised fans noticed. Fans also noticed that Sam is wearing Dean's gray hoodie in the scene in the kitchen after Dean dies. This isn't the first time the boys have [[Clothing Catalogue|worn each other's clothes]] and yes, the fans ALWAYS notice. In [[1.12 Faith]], Dean wore Sam's gray hoodie, so Sam wearing Dean's hoodie now may be another example of circular storytelling on Jared's part.

Sam's first case after Dean's death is in Austin, which is home to both Jared and Jensen. Texas is also the location of Jared's next film project on the CW: ''[[Walker]]''.

The face of Sam's wife is not seen as she is only shown at a distance. In a private online meet and greet with Jared after a Creation StageIt event, a fan asked if this person is anyone specific. [https://twitter.com/TeamFreeWillBT/status/1330697516262645761 Jared answered] that no, this person's identity was left open to fan interpretation. Many fans were disappointed that this person was not [[Eileen]], and showed an outpouring of love and support for [[Shoshannah Stern]] on [https://twitter.com/Shoshannah7/status/1330671102935240705 her twitter].

Despite [[Belphegor]]'s statement in [[15.02 Raising Hell]] that a soul cannot go to Heaven once it has been condemned to Hell, Dean still reaches Heaven when he dies despite his deal having previously condemned him to Hell, suggesting that Jack changed the rules of entry in addition to restructuring HevenHeaven.

The clothes Sam and Dean are wearing when they meet up in Heaven are similar to the outfits they wore in [[1.01 Pilot]]. Significant scenes in the pilot also occurred on a bridge. Jared revealed at a [https://www.youtube.com/watch?v=2oVQe8h0-H4 StageIt Creation event after this episode ] that for Sam, the outfit was his idea, as he asked the wardrobe department to put him in the outfit from the pilot, and since they no longer had it, they matched it as much as possible. }}{{TriviaQuote |Text='''Dean II:''' Dad. It's okay. You can go now.:''[https://www.youtube.com/watch?v=2oVQe8h0-H4 As he described at the November StageIt panel], it was Jared's idea to mirror Dean's death with Sam's. The line "You can go now" was inspired by what director Bob Singer related he had said to his own father.''}}{{TriviaQuote |Text=Though Sam's son has an [[anti-possession tattoo]] on his arm, there are no other signs of hunting in Sam's life after he leaves the Bunker. [https://www.youtube.com/watch?v=2oVQe8h0-H4 Jared confirmed at the November StageIt panel] that Sam has not been hunting "in honor of Dean" because Dean wouldn't have wanted him to, but that Sam did tell his son about hunting and about his Uncle Dean, and that the decision to get the tattoo was Dean II's.}}{{TriviaQuote |Text='''Dean:''' Hey, Sammy.<br>'''Sam:''' Dean.:''Another reference to the first word spoken by Sam to Dean in [[1.01 Pilot]], [https://www.youtube.com/watch?v=2oVQe8h0-H4 adlibbed by Jared] with the circular storytelling of returning to the pilot in mind.''

[https://www.youtube.com/watch?v=2oVQe8h0-H4 At a Stageit event by Creation ] the weekend after this episode aired, Jared revealed that he considers this finale his favorite episode of the show, followed by [[8.23 Sacrifice]] and [[6.15 The French Mistake]].
