Lt. Barclay programmed the Enterprise holodeck to create a version of Counselor Troi, which was shall we say, heavenly. The Greek idealized counselor wouldn't only preach to anyone ill advised to listen to preachy sermons on being one with your emotions, but would carry on romantically with Master Barclay of the holodeck.
Barclay, played by Dwight Schultz, would have to finally admit the extent of his holodeck addiction. In coming clean, he would gain more strength and control of his real life, by setting aside his fantasy life of playing in his holographic dream world. While it lasted though, for Barclay anyway, it was one hell of a good time.
