Twenty-three-year-old Lindsay Kantha Souvannarath of Geneva, Ill., and 21-year-old Randall Steven Shepherd of Halifax are each charged with conspiracy to commit murder, conspiracy to commit arson, illegal possession of dangerous weapons and making a threat through social media.
The inquiry convened for two days earlier this month.
There is a publication ban that prohibits reporting what is heard in Halifax provincial court.
The Crown alleges the two accused, along with a 19-year-old man found dead in his Halifax home, had planned to attack the Halifax Shopping Centre on Valentine's Day.
None of the allegations have been proven in court.
