Character Revelations

  • Questions about Gillies being alive or dead are answered and resolved, finally.
  • For the first time, Murdoch takes a page from Brackenreid's handbook of interrogation.
  • Crabtree is called "...that cheerful Chipmunk you worked with..."
  • When James Gillies' jumped off the bridge (ep.709) he smashed his face on one rock and crushed his spine on another, driving bone shards into his vertebral nerves keeping him in agonizing pain.
  • Julia's phonograph (repaired by William last Christmas) is back in the City Morgue.


Historical References

  • Reginald Aubrey Fessenden (1866 - 1932) was a Canadian inventor who performed pioneering experiments in radio, including the use of continuous waves and the early—and possibly the first—radio transmissions of voice and music.
  • Rubber bullets(used today in riot control) are part of a long line of development of non-lethal cartridges that dates back to the use of short sections of broom handle fired at rioters in 1880s.
  • Hanging was the only method of execution used in Canada and was in use as possible punishment for all murders until 1961, when murders were reclassified into capital and non-capital offences. The death penalty was restricted to apply only for certain offenses in the National Defence Act in 1976 and was completely abolished in 1998. The last hangings in Canada took place on 11 December 1962.
  • After the Ball is a popular song written in 1891 by Charles K. Harris. The song is a classic waltz in 3/4 time.
