An admiral of Starfleet Security who comes aboard the Enterprise-D to observe Norah Satie's inquiry and silently ends it by walking out during her outburst against Picard.
Admiral Thomas Henry is a senior officer of Starfleet Security who appears in the fourth-season episode The Drumhead, set in 2367. He is played by Earl Billings.
Retired Admiral Norah Satie's investigation aboard the Enterprise begins with a genuine Klingon spy and a suspected act of sabotage, and widens into a hunt for conspirators that settles on the young crewman Simon Tarses. When Picard objects, Satie summons him to testify and invites Henry to attend the hearing.
Picard quotes the words of Satie's revered father on the first link in the chain of tyranny. She loses her composure and denounces him in a furious tirade. Henry says nothing: he stands up and leaves the room, and the hearings are called off soon afterwards.
