Star Trek: 10 Things You Didn't Know About Lt. Barclay

10. He Has Something In Common With Seven of Nine

Reg Barclay suffered from a few physical and mental ailments in his time on the Enterprise. One of these was an addiction to the holodeck, dubbed "Holo-addiction" or "holodiction". Given the opportunities presented by Star Trek's holographic technology, it's surprising that this wasn't a more common affliction in the 24th century.

Struggling to form connections with other members of the crew, Barclay retreated into a fantasy world where he could be the charming, romantic hero he wanted to be. Barclay is helped with his addiction by Geordi LaForge and Deanna Troi, who help him form real-life connections with his crewmates. His obsession with finding the missing USS Voyager leads to a relapse in the season 6 episode Pathfinder, when his obsession leads him to create a fully functional replica of the ship and its crew.

In Voyager season 7, holodiction grips Seven of Nine, when she too becomes obsessed with a holographic representation of Voyager and its crew. In Human Error, Seven attempts to improve her social skills, but becomes increasingly overwhelmed by the emotions these new connections stir up. Seven's obsession alerts the attention of Janeway, who chastises her for spending too much time on the holodeck instead of fulfilling her duties.
