Dr. Bekker says to tell Dr. Van Eeghen that Finland won the World Cup. This is either a difference from our world, or perhaps more likely a cruel joke (Dr. Bekker does not seem to have much respect for Dr. Van Eeghen). In our world, Finland's national football team has infamously never even qualified for a finals tournament of the World Cup.

Livinia Nixon, who plays the female morning show host Pam Jolly, is in fact a popular Australian host and weather presenter on the GTV-9 network.

The song 'This Love Is Over', by Ray LaMontagne and The Pariah Dogs plays over the opening credits sequence for this one episode only.

Bruce, the G'Day Melbourne host, says the theme of this year's Spring Fashion Ball was "under the sea," continuing the season's flood references.

Ironically, if the viewer freeze frames Matt's book when Kevin is reading it in the hotel room, much of it is about Kevin going to Laurie in "A Most Powerful Adversary" and Laurie trying to tell Kevin that he is suffering a delusion. Although Matt's text is dismissive of Laurie, claiming that "her knowledge of the mind had limited her knowledge of the spirit," later events in this episode make it seem that Laurie might well have been correct.

The G'Day Melbourne morning show is fictional. (Coincidentally, there was a morning show entitled Good Morning Melbourne which ran from 1981 to 1988 on Network Ten.)

Chief Inspector Kevin Yarborough's hometown Makarra appears to be fictional, like Kurripa in the prior episode (as well as Mapleton and Jarden).

Dr. Van Eeghen, the inventor of the LADR machine, is named after series editor Henk Van Eeghen.

Dr. Eden speaks in Dutch when not conversing in English, whereas Dr. Bekker speaks in Russian (presumably they understand each other, but are more comfortable speaking in their respective native tongues).

Nora references Jesus Christ Superstar, Andrew Lloyd Webber and Tim Rice's 1970 stage musical based on the life of Christ.

Nora says she has Global Entry, a US Customs and Border Patrol service that allows pre-approved travelers to receive expedited clearance upon arrival in the US, as well as access to expedited screening via TSA PreCheck when leaving the country for certain international destinations.

When Kevin saw Evie on the Hotel's TV, she was holding a flyer that reads the phrase "Surah 81". This is a reference to the 81st chapter of the Quran, the Muslims holy book. This chapter is named "Al takwir" ("The Conglomeration"). It tells about signs of the coming of the day of judgement. Some of these signs include the following: (a) When the sun is shrouded in darkness (turns into a sphere) (b) When the stars lose their light (c) When the mountains are made to vanish (d) When the seas boil over (e) when the she camel about to give birth is left untended. It also prominently features the live burial of a baby girl which might refer to the topic on the minds of both Kevin, who remembers tossing little Patti Levin down a well in his afterlife experience, and Nora, who bitterly resents her choice to give away adopted daughter Lily.

Kevin having trouble turning the hotel room TV off, and him thinking Evie is communicating with him through the TV, calls back to Kevin Sr.'s appearances in "International Assassin." Likewise, Kevin Sr. saying at the end of the episode that he saw Kevin Jr. on TV is an inversion of "International Assassin."

The man at the bus stop suggests that the mother could run off, leaving Nora with the baby. In "International Assassin," Patti claims this happened to her on the campaign trail in Iowa.

It is ironic that Kevin and Nora's final argument is in part about having a baby. The first thing Nora ever said to Kevin in "B.J. and the A.C." was, "What's up with the baby?" when Kevin was carrying the Jesus baby doll.

Kevin requesting a book with the rather alarming (when coupled with his erratic behavior) title Assassins is an obvious callback to his chosen profession in "International Assassin," an experience which seems to be particularly on his mind throughout this episode.

Nora gets asked the same question the man who self-immolated in "Crazy Whitefella Thinking" was asked. Interestingly, Nora and the man give opposite answers, yet both are rejected. Damon Lindelof has suggested that the scientists are not looking for a specific verbal answer, but rather are measuring attachment: "Both of them gave answers that suggested to the questioners that they were still attached."

Rather oddly, fire trucks materialize behind Pam in the presumably stock G'Day Melbourne backdrop (they can be seen when she asks Georgie the pancake chef if he is ready, and they are not present in the earlier identical shot). In addition to foreshadowing the ending of the episode, it is possible that the fire trucks are not actually there and are an early hint of Kevin's deteriorating mental state (calling back to the firemen responding to the hotel in "International Assassin").

The beeping fire alarm, evacuation, and responding firefighters at the hotel call back to "International Assassin."

Daniah (at Laurie's instruction) says, "There is no family," a G.R. tenet previously stated by Patti in "B.J. and the A.C." and by Tom in "I Live Here Now."

The more potentially interesting/strange signs on display in the background of the pancake cook-off include: "Is the grass greener on the other side?"; "Save me" with a drawing of a whale; "Free hugs"; "Kiss me Bruca" (presumably referring to G'Day Melbourne co-host Bruce Quartermain); "Give us the truth" (with a number 7); a sign depicting the "all-seeing-eye" pyramid (a symbol often associated with Freemasonry and various conspiracy theories) beaming people up into space, with captions that appear to read "We are not alone" and "They were taken"; and a simple sheet of paper with "Always on me" handwritten on it. A woman Kevin shoves past wears a T-shirt with several handwritten slogans on it, including: what appears to be the word "Lckin," "U Melbourne," "Dog Beer Ute Misses," "A bad day huntin' beats a good day workin'," and "Bucks & Boars" (the latter is the mascot for the University of Melbourne).

The closing song was A-ha's "Take On Me," which was also heard in a couple of different versions throughout the episode. The award-winning "Take on Me" video is about a man and a woman who find each other even though they're confined to alternate universes.
