Spoilers for "Star Trek: Starfleet Academy" episode 4, "Vox in Excelso," to follow. "Star Trek: Starfleet Academy" is utterly unafraid to embrace being a school show. Now, its fourth episode, "Vox in Excelso," has shifted its attention to something even more exciting: a debate team, coached by the Doctor (Robert Picardo). Trekkies might recognize those words, because they were actually written for an episode of "Star Trek: The Next Generation" — specifically, "The Drumhead," written by Jeri Taylor. Criminal investigator Admiral Norah Satie (Jean Simmons), the daughter of the late Judge Satie, is sent to the Enterprise to investigate, but she gradually starts abusing her power, looking for evidence of a larger conspiracy that doesn't exist.
