The blood Delphine (Evelyne Brochu) draws from Cosima (Tatiana Maslany) is in a yellow top vacutainer tube. Yellow tops contain the anticoagulant sodium polyanethol sulfonate (SPS). SPS is primarily used on blood drawn for microbiological culturing but is also acceptable for DNA and RNA studies.
Matt Frewer (Dr Leekie) and Julian Richings (Ben) played two of the 4 Horsemen of the Apocalypse (Pestilence and Death) in Supernatural (2005).
Even though episode 1.10 (Endless Forms Most Beautiful (2013)) was set in December 2012, Aynsley's grave lists her year of death as 2014.
