(DW: The Sontaran Strategem - although the events of 9/11 have yet to be specifically referenced on screen, Donna Noble references "Gitmo" a.k.a. the US military base at Guantanimo Bay, which became known as the main holding facility for "enemy combatants" following the attacks; the reference to "Homeworld Security" is a direct reference to the term "Homeland Security" coined in the days following 9/11. TW: Fragments also makes veiled references to the post-9/11 security climate.)
