Shortly after he enters, Erick Avari says, "...So, we moved the sarcophagus from the Egyptian room to the lecture hall." This is a reference to his role of Dr. Terrence Bey in The Mummy (1999).
This episode, like a few others, shows Nate reacting as his son flat lines. This is the only time however that Maggie is also shown.
When Doctor Lloyd (Erick Avari) is reading off the list of dead scholars associated with the sarcophagus' "curse", the second name is "Doctor Schliemann - London Museum - Dead" Heinrich Schliemann (1822-1890) was a German businessman obsessed with Homer who excavated a site in Turkey which, he claimed, was the Troy of the Iliad. Schliemann died of the complications from a chronic ear infection. Shliemann was not a doctor or professor; at the time of his activity, archaeology was not yet an organized discipline.
The painting prominently featured in the gallery is (presumably a reproduction of) Vermeer's "Girl with the pearl earring"
Erick Avari plays a museum employee who is tricked into believing that he is suffering from a mummy's curse. In the Castle (2009) episode Wrapped Up in Death (2010), he plays Rupert Bentley, the financier of the expedition that found the mummy at the center of investigation, which also involves a mummy's curse.
