I think, if your friend is going to get the TNG bug, it will get them regardless of which episode it is. "The Royale" is a good early episode, a classic sci-fi type, kind of Bradbury esque I believe. It's not quite on my A list but should have done the trick.
You could try 2 or 3 episodes if you know what type of sci fi your friend prefers - time travel, space battles/borg, Q, Family episodes, Weird shit happening in space episodes (tend to be my favorites - Phantasms
