Reply #4: Three good suggestions

[Orrex]

At one point Q is pouring his heart out to Picard, who flatly refuses to be Q's "father confessor." Q describes himself as "the king who would be man," and he also describes Data as his "professor of the humanties." Really sharp writing throughout. Was that Q Who? I don't want to lose my geek-cred by Googling, so a guess will have to do.

Best of Both Worlds I is excellent, and one of the all-time best cliffhangers IMO.

I think that the DS9 episode was Trials and Tribblations, or something similar. That was also a great one, very tightly written, and it obliquely set up the answer to the head-ridge question so elegantly answered years later by ST:ENT.
