What was originally slated to run in December has been bumped to 2013 - the final two episodes of the Showcase show "Haven" will air in January instead.
An article on cinemablend.com cited last Friday's shooting in Newtown, Connecticut for the delay - Syfy’s "Haven" was apparently scheduled to revolve around violence in a school, so the episodes were slightly delayed. "Due to the timing of last Friday’s episode, which would have aired the same day news of the Connecticut shooting broke, the network postponed the episode, cancelling last week’s airing out of respect for the victims, their families, and those who were keeping vigils or watching the news. At the time, the network had to balance potentially irritating fans and sensibly responding to the tragedy, and Syfy made a tough call."
According to a press release for the Canadian network Showcase, that carries the show, episodes 312 “Reunion” and 313 “Thanks for the Memories” have been removed from the December schedule. A repeat airing of the Season 2 Christmas episode “Silent Night” will now air on Friday, December 21 at 9 pm ET/6pm PT instead of at 11pm as previously scheduled. Episode 312 “Reunion” and the Season 3 finale, “Thanks for the Memories” will air back-to-back on Friday, January 18 beginning at 8pm.
