An excerpt:
It’s interesting, I haven’t seen anybody mention “All Good Things…,” The Next Generation‘s final episode, on any of the lists of TNG episodes to watch before starting Picard. (I may have just missed it.) Yet “Maps and Legends” makes two overt references to “AGT.”
The first comes when Picard talks to Dr. Benayoun, his former medical officer on the U.S.S. Stargazer (Picard’s first command). Picard wants to be medically certified to travel through space again, but Benayoun says there’s one catch: damage to his parietal lobe that is very likely to develop into one of several nasty brain-injury syndromes. Picard mentions that “a long time ago” he was warned of this possibility, and that’s a direct reference to “AGT,” where we saw a possible future in which Picard is retired from Starfleet, living on the family vineyard, and has Irumodic Syndrome (which is, basically, Space Alzheimer’s). It’s good to see this is being remembered, and also lends a sense of urgency to Picard’s actions, as he doesn’t know when his brain is going to start to betray him.
Indeed, it may have already. While he’s joking, Benayoun does mention irrational anger during live interviews as a symptom of this condition. It also casts a doubt on everything he’s doing, truthfully.
