"He's alive & killing it."
Dexter: Resurrection - Easter Eggs & Hidden Details
Easter Eggs
Hallucinatory return of Brian Moser, the Ice Truck Killer.
In the finale, Dexter hallucinates his adoptive brother Brian Moser (played by Christian Camargo) for the first time since the original series. Brian taunts Dexter about his attempts to be normal, representing the purest, most unapologetic version of Dexter's murderous instincts. This cameo serves as a deep cut for longtime fans and a symbolic representation of Dexter's internal struggle between his 'code' and his pure 'passenger'.
Detective Wallace's theme song is "Stayin' Alive" by the Bee Gees.
In the finale, Detective Claudette Wallace has a scene featuring her theme song. This is a fun, character-building detail that adds a layer of personality and swagger to the NYPD detective investigating the case, giving a cinematic flourish to her moment of triumph as she uncovers the identity of the New York Ripper.
