The anthrax is delivered and released in a very similar manner, in this episode, to an episode of Michael Weatherly's earlier series "NCIS:" "SWAK (2005)," in which his character was dosed.
This episode starts with a video of Michael Weatherly advising audiences that the episode was filmed months earlier and a work of fiction unrelated to the at-the-time ongoing SARS-CoV-2 (COVID-19) crisis.
