ST:TNG:42 - "Q Who?" (Stardate: 42761.3) - this is the 16th episode to air in the second season of The Next Generation and a pivotal episode at that. Q makes a comeback (for the first time in the second season) to take the Enterprise 7000 light years from home to get them to encounter a new enemy that was only hinted at in "The Neutral Zone" - the BORG. With this episode, The Next Generation begins to come out of the shadow of its mighty predecessor, The Original Series, because the Borg will soon become as memorable as the Klingons and Romulans. We also find out more about Guinan (played by Whoopi Goldberg) and her past - and her past includes Q meeting her 2 centuries ago! This is definitely a welcome episode that makes The Next Generation truly unique.
Oh, and lookout for a nervous ensign spilling hot chocolate onto Picard!
