[EX Q]: Passage: Free-agent goaltender Jeff Hackett was signed from the Boston Bruins to replace Roman Cechmanek and challenge backup Robert Esche for the number one spot in 2003–04, but Hackett was forced to retire in February due to vertigo. During the course of the season, serious injuries suffered by both Jeremy Roenick (broken jaw) and Keith Primeau (concussion) in February forced the Flyers to trade for the Chicago Blackhawks' Alexei Zhamnov, who filled in well and kept the Flyers afloat. Esche entrenched himself as starter and remained in that position even after the Flyers re-acquired Sean Burke from the Phoenix Coyotes, as the Flyers clinched the Atlantic Division title over the New Jersey Devils on the last day of the season.

[EX Q]: Passage: Although Scream of the Shalka continues the narrative of the original 1963–89 programme and the 1996 television film, the show's 2005 revival ignored its events. The series was scripted by veteran Doctor Who writer Paul Cornell, with Richard E. Grant providing the voice for the Ninth Doctor. This performance followed years of rumours that Grant would play the Doctor in a film or new series, and indeed he had appeared as the "Conceited Doctor" in the Comic Relief special Doctor Who and the Curse of Fatal Death in 1999. Grant subsequently went on to appear in the revived television series of Doctor Who as a guest villain in 2012's "The Snowmen" and 2013's "The Bells of Saint John" and "The Name of the Doctor". The Doctor's companion for this adventure, Alison Cheney, was voiced by Sophie Okonedo who a year later would be nominated for an Academy Award for her performance in Hotel Rwanda. She also appeared in the 2010 series of Doctor Who, as Liz 10, in the episodes "The Beast Below" and "The Pandorica Opens". Derek Jacobi reprised his role as the Master in 2007's "Utopia". David Tennant appeared in a cameo role as the Caretaker, later being cast as the Tenth Doctor in 2005.
