Season 4's "The End in the Beginning" differs from other Bones episodes because it's almost entirely a dream sequence. In the previous episode, FBI agent Seeley Booth had been diagnosed with a brain tumor. The operation to remove it is a success, but he has an adverse reaction to the anaesthetic and is put in a coma. What we see in the season 4 finale is Booth's coma dream, inspired by the novel Bones is writing at his bedside.
We get to see every cast member flex their acting muscles by playing their characters within Booth's dreamscape. Rather than working for the FBI, Dream-Booth and Dream-Bones are married nightclub owners. Angela is their hat check girl, Hodgins is a regular customer (and crime novelist), and even Zack reappears as Brennan's assistant.
The episode is full of Easter Eggs. Sweets plays a bartender who also plays keyboards in a band called Gormogon. "The name of the band is Gormogon," he says. "Some people think that I'm Gormogon, but I'm not," referencing a season 3 fan theory that Sweets was the serial killer. The band is played by John Francis Daley's real life band, Dayplayer. The episode features yet another rock and roll cameo by Mötley Crüe. The Crüe joins ZZ Top's Billy Gibbons and Cyndi Lauper as rockers in the Bones-iverse.
What sets the season 4 finale apart, though — besides all the dream stuff — is its sweetness. Years before Booth and Bones actually hook up, it gives viewers a peek into their future married life. Had the show not been picked up for eight more seasons, it would have been a fitting series finale.
