First Contact: ‘The Nth Degree’ Season 4 Episode 19

Remember Barclay? He was more entertaining than most of the series regulars so when you come up with a good story,  you might as well give it to him. While out repairing the Argus Array, Reg gets knocked out by a weird space ray from a probe but quickly recovers. He’s not the same after, displaying intelligence, insight and confidence. But as his intelligence increases as does his insubordination. Eventually he hooks himself up to the computer via the holodeck and becomes the computer. His goal is to transport the ship across the galaxy, but what awaits the Enterprise when it arrives? Why, it’s a big floaty head.
