The closing ice rink sequence is a strong echo of the scene in Buffy where Angel takes Buffy skating and is seen by Bianca Lawson's character Kendra.
In the sequence with Luc Robitaille, Booth (David Boreanaz) wears a Philadelphia Flyers shirt. The name and number on the shirt refer to Bobby Clarke, a famous Flyers centre and manager.
When Booth is examining the list of team members on his computer, the final name on the list is Noah Harley, one of the show's writers.
When Special Agent Payton Perotta says "I favor backseats myself," it is a reference to a scene Marisa Coughlan had as Ursula in Super Troopers (2001) .
