Not my favorite, but.. "The Squire of Gothos" is not my favorite, but this episode is actually explained in the Next Generation episode of "Encounter at Farpoint". Rent the episode, Q has a conversation with Picard when they 1st met. Fascinating. Trelayne believe it or not, is a member of the Q continuum. Isn't that a scream!! Apparently, Trelayne was an early attempt of the Q continuum. The Next Generation explains a couple of episodes from the 60's series, and Deep Space 9 dedicates an episode from "The Trouble with Tribbles". The facts about the Klingons from the old series has an explanation as well. There is also a link between Guinan, Q and The Borg from the novel Vendetta. There are a few theories and links between the Borg and Q in both TV series.
