I don't know. I think 'Q-Less' a good TNG episode that's going through the motions of being a DS9 episode. It's about that romantic triangle between Q, Vash and Picard without the third end, with both Q and Vash looking forward to their next encounter with the flagship captain. O'Brien sits around expoisiting TNG plots, but forgets to mention 'Encounter at Farpoint', which seems to be the loose inspiration for the crisis plot and Q's relationship to it. Q gets to deride the DS9 crew with his usual wisecracks, tartly observing that O'Brien was 'one of the little people' on TNG, but most memorably this:
Q: You hit me. Picard would not have hit me!
Sisko: I'm not Picard.
Q: Indeed not. You're much more easier to provoke. How fortunate for me.
Which is also kind of why the relationship really didn't work. Q couldn't get the 'witty repartee' he sought for in Sisko, just a knockdown punch.
I'll say this, though. I wish he'd come back after Worf came onboard. 'Growl for me Microbrain, show me you still care!'
On the other episodes: 'Captive Pursuit' is great as ever, 'Babel' was okay, actually, better than I remembered it. 'Dax' is an interesting episode that plays around with the idea of Trill symbiosis but doesn't come to a concrete answer, using a last-minute relevation to solve its plot machinations instead. No real clunkers so far.
